Summoning lesser demons in Stormbringer is what my Brit friends might call a 'sticky wicket.' There are basically three things to consider:
1) The charming but incomplete early rules (1-3E)
2) The detailed but bloated point buy of later rules (4E)
4) The original fiction
Each of these has their peculiarities. I want to keep the 1E demon types (Warrior, Guardian, Transport, Knowledge, Passion), as these have a certain charm and could be inferred based on the demons Moorcock describes. As for the 4E demon point-buy system, although I appreciate the legwork done by the designers, I find it a clunky consumer catalogue that slows down the game. Moreover, I dislike the 4E assertion that the summoner has complete control over the entity summoned, especially this farcical fast food analogy from the designer:
Imagine this as if you were going out to eat at a restaurant. If you pull up to the Drive-Thru window at a fast food joint your food will only take minutes to arrive, but it is cooked the same as everyone else’s, you can never be sure you got what you ordered until you look into the bag, and once you have checked your order you are 15 miles away, and it is too late to complain. However if you go to a fancy gourmet restaurant, you can have your meal cooked as you like it, waiters are constantly pestering you to make sure the food is alright, and if something is wrong with the meal you can have it fixed as you go. [5.3.1.1]
This is pretty crude reasoning, first and foremost because it conflicts with Moorcock's fiction, where mortals beg for arcane help, but have no say in its shape or form. Elric doesn't 'order' an Arioch set with a side of Beast Lord to go, he cries out in need and takes what he can get. In Corum's world, the Nadragh sorcerer Ertil also has to beg to be heard, and the demon Yrkoon is irritated at being summoned so often by him:
Yrkoon: "You summoned me again, Ertil."
Ertil: "Yrkonn, we need more help from your master, Mabelrode."
Yrkoon: "More help? More?"
Ertil: "We work for him! Without us, you would have no means of reaching this realm at all."
Second, point-buy detracts from good roleplaying, because it is open to abusive power gaming. In fact, giving players complete control over demons seems to contradict the designer's own advice:
The point of designing the demon is not always to design the most powerful demon possible by bending the rules. [5.6.1]
To defuse this situation and return to emulating Moorcock's writing, I suggest that for lesser demons the GM should either 1) have a concept in mind and build it from the options below and his own imagination or 2) roll randomly and adjust as needed.
4b) Type 2 Demons - Lesser Demons
Lesser demons are the demons proper of Stormbringer summoning. The majority of lesser demons are completely alien in origin, although some rare instances of humans raised to the position by a Chaos Lord can be found (see Yrkoon from the Corum Chronicles). Arioch did promise to make Elric a god at one point, so I assume that this principle also works for the Young Kingdoms. Lesser demons can also be avatars of Chaos Lords, as when a puppet form of Arioch devoured the guards in Cymoril's chambers to let Elric escape at the start of The Dreaming City.
1) How to Summon - These are summoned as per the rules using the Sorcery Skill above, plus the Sacrifice, Binding, and Object rules given below.
1.1 Grimoires
Although in Moorcock's Elric books he often mentions Elric or Yrkoon's grimoires, these are largely overlooked in the RPG. The only mention of a grimoire in the rules is [5.3.2], where studying one for 40-INT months (why?) and making a POW x 3% roll (why not INT?) gives an increase to the sorcerer's rank.
Ho hum.
First of all, Elric summons elementals without need of a tome. I'd like to keep non-demonic magic simple in this way.
Here is my simple mechanic to emulate the importance of grimoires.
1) Sorcerers need a grimoire for every demon type they want to summon. When the sorcerer is created, if he or she is Second rank or above, he starts with a grimoire for the first type of demon (Warrior, Protection, Knowledge, Travel, or Desire) he summons. To summon any other type, the sorcerer needs to procure a grimoire by adventuring.
2) Sorcerers need a grimoire for each Lord of Chaos, Beast Lord, or Elemental Ruler they want to summon.
3) Sorcerers need a grimoire to increase their rank if their attributes allow it, as per the original rules. However, switch the POW x 3% roll to a Sorcery skill roll.
1.2 Sacrifices When Summoning Demons
For non-noble sorcerers, summoning a demon requires the summoner to sacrifice another being, or a more personal sacrifice. This is seen more in the Corum books than in Elric:
Glandyth-A-Krae: "I want power, demon! Power to destroy Corum and Law's rule on this plane, demon! Give me that power, demon!"
Yrkoon: "I cannot give you power, I can only tell you how to get it. If you like more of Chaos' gifts, you will assume the attributes of all those who accept such gifts. Are you prepared to become what you loathe?"
Glandyth-A-Krae: "What is that?"
Yrkoon: "A shefanhow! A demon. I was human once."
Glandyth-A-Krae: "I'll make any bargain to have my revenge on Corum and his kind!"
1.3 Types of Sacrifices for Summoning & Binding Objects
Non-Noble sorcerers must make the following sacrifices when summoning lesser demons:
Warrior - The life of a warrior, be it friend or foe. The demon's physical attributes (STR, CON, and DEX) are also limited to no more than those of the sacrifice, so the healthier the sacrifice the better. For binding, a weapon or armor of at least 1000 SS value is also required.
Protection - The life of a faithful pet they have raised. Most common are dogs, cats, or crocodiles. The demon's physical attributes (STR, CON, and DEX) are limited to those of the sacrifice, so the healthier the sacrifice the better. For binding, a statue of the sacrifice of at least 1000 SS value is also required.
Knowledge - A trained intelligent animal or slave. The demon's mental attributes (INT and CHA) are limited to those of the sacrifice, so the healthier the sacrifice the better. For binding, a reflective object (mirror, orb, crystal, etc) of at least 1000 SS value is also required.
Travel - A coin of great value, such as a Melnibonean wheel or high karat stone, which is consumed in the summoning. Should require great travails or quests to obtain. For binding, a vehicle of at least 1000 SS value is also required.
Passion - A charismatic person. The demon's relevant physical attributes (CON and CHA) and gender are limited to those of the victim sacrificed, so the kidnapping of beautiful youths for summoning succubi or incubi has become a scourge of chaotic nations. For binding, a piece of jewellery (ring, necklace, torc, bracelet, etc) of at least 1000 SS value is also required.
(Note: Binding object prices are in Small Silver (SS) and not Large Bronze (LB) because Merchants are the lowest class capable of becoming sorcerers. Since in a previous post I linked social class to wealth, the merchant coinage of SS seems reasonable for pricing weapons or armor strong enough to hold demons).
1.4 Sacrifice & Social Class
As mentioned above, if the sorcerer is of imperial or royal blood from a Chaotic nation, they are exempt from making a sacrifice. Elric often merely offers as many souls as they can take to demons, and neither sacrifices others or himself for his summonings of Arioch. I find this principle of noble exception in keeping with the source material, and gives a good reason why Mabden sorcerers like Thelab Karna envy Melniboneans.
In keeping with this, Noble sorcerers from Chaotic lands do not need to make any overt sacrifice, but will be played by Chaos in return for any aid they receive. Unlike Glandyth and his Nadragh sorcerer, Elric didn't make any immediate sacrifices to obtain demonic aid, but ended up paying in other ways.
2) Demon Attributes & Skills
The more powerful the sorcerer, the more powerful demon he or she can summon. Therefore, I am linking demon attributes to the sorcerer's POW to reduce calculations or dice rolling.
2.1 All demons have three types of attributes
1) POW, which is 3D8 unless an increase to POW is randomly rolled.
2) Major attributes, determined by their demon type below, which are equal to the sorcerer's POW.
3) Minor attributes, determined by their demon type below, are equal to half the sorcerer's POW.
2.1.1 Major and Minor Attributes
Warrior - Major are STR, CON, SIZ, and DEX, all else Minor.
Guardian - Major are STR, CON, DEX and INT, all else Minor.
Knowledge - Major are INT and CHA, all else Minor.
Transport - Major are STR, SIZ, and CON, all else Minor.
Passion - Major are CHA, INT, and DEX, all else Minor.
(Reminder: If the summoner is not a Chaotic noble, demons he or she summons will have attributes restricted to the values of their sacrifices as outlined above.)
All other attributes are equal to how much POW the summoner spends on the summoning, with a maximum limited by the attribute of the sacrifice given as outlined above.
Example
If a Sorcerer of POW 18 summons a Warrior Demon, the POW is determined by rolling 3D8. The demon has STR, CON, DEX, and SIZ of 18, but INT and CHA of 9. Its POW must be rolled on 3D8. If the sorcerer is not a noble, these attributes are also limited by the sacrifice as outlined above.
2.2 Demon Skills
If you don't want to spend time calculating skill percentages, all demon skills should be at 60% unless you need them to be higher or lower. Otherwise, calculate as below:
Warrior - Attack and Dodge at DEX x 3%, Parry at STR x 3%
Guardian - Attack and Dodge at DEX x 3%, Parry at STR x 3%. All Perception skills at INT x 3%.
Knowledge - All Knowledge skills at INT x 3%, all Persuasion skills at CHA x 3%
Transport - Navigate and Make Map at INT x 3%, Dodge at DEX x 3%, any other appropriate movement based skills at relevant attribute x 3%.
Passion - All Communication skills (Persuade, Credit, Orate, Sing) at CHA x 3%,
3) Demon Abilities
I have taken the liberty (and it has used up my days of liberty) to re-organize and clean up the list of Demonic Powers [5.7.1] from Stormbringer 4E into ten categories: Defense, Melee Offence, Missile Offence, Area Offence, Random, Land Transport, Air Transport, Sea Transport, Psionics, and Sense. Each Lesser Demon has 4 powers, chosen or rolled from the categories below.
Warrior - One Melee Offense, one Missile Offense, one Defence, and one Random power.
Guardian - One Melee Offense, one Area Offense, one Defence, and one Random.
Knowledge - One Psionics, one Defence, one Senses, and one Random.
Transport - One Travel (appropriate to environment), one Defence, one Random, and one Senses.
Passion - Two Psionics, one Random, one Melee Offence.
Area effect attacks do not affect their compatriots.
NB: Ranged powers have an area equal to demon POW, basically affecting anyone engaging in melee.
DEFENCE
1 Acid Blood - Acid sprays if wounded, attackers in melee must make a POW x 3% save or take 1/2 demon POW (round up) max die damage (ie 20 POW is 1D10).

4) Other Notes
Demon Power Level
Demons generated in this way can be considered to be over-powered in modern gaming parlance. Good. This is exactly how they are in Moorcock's fiction. Elric only survives lesser demons because he has a greater demon, Stormbringer, by his side. Player characters should be willing to turn tail when facing a demon.
Turning Against the Summoner
Lesser Demons can’t use their abilities against the summoner unless the negotiation fails, they are let out of the octagon without an agreement, or they are ordered to do so by a Chaos Lord. Remember, use the Demon Reaction table from the previous post on summoning to determine how cooperative the demon summoned is.
Perils of Using Demons
If a sorcerer uses demons, he faces several perils. First, the demon may be unhappy, and want to take vengeance at some point. Second, the aims of Chaos are inscrutable, and a sorcerer going against them will face consequences (NB: Greater Demons are autonomous and largely do as they want). Finally, anyone using demons will come under the scrutiny of Priests or even Agents of Law, and thus should expect periodic attacks from them.
Designed vs Random Demons
On the one hand, if possible GMs should design demons from the above lists to fit the adventure and locale. Creating a giant bat-thing guardian with Bat Wings, Sonar, and a Plague Attack would fit well with a cave adventure. However, this means GMs will have to be creative and do lots of legwork. On the other hand, random demons force both the players to be creative to find a way to overcome them. Since this challenge is an essential part of Moorcockean roleplaying, I suggest going this route.
Example Demons
1) Created Demon
Let's make the Bat-Thing Guardian from the example touched on above. It needs 4 demon abilities, so I choose Mouth, Plague Attack, Sonar, and Bat Wings. Since guardians are supposed to have one Melee Offense, one Area Offense, one Defence, and one Random, this bends the rules a bit, switching Defence and Random abilities for Flying Transport and Senses. This is no problem since it fits the concept.
As for attributes, they will be as follows:
STR, CON, DEX and INT are equal to the sorcerer's POW, all other attributes are at 1/2 POW. If the demon's summoner is unknown, sorcerer POW should be considered a minimum of 18, or higher if a summoner of greater power.
With regards to skills, they are as follows:
Attack and Dodge at DEX x 3%, Parry at STR x 3%. All Perception skills at INT x 3%.
The Bat-Thing Guardian will thus have Bite and Dodge of 54%, with the former doing 1D10 damage. It will also have 18 HP, but no armor. It may seem weak, but the Plague Attack and deafness from Sonar, as well as its ability to fly out of reach, should make it a worthy challenge.
2) Random Demon
OK, let's roll the bones and see what we get. Once again, let's make a Guardian to see how it compares to the created demon above.
As for the demons attributes, they will be as follows:
POW I roll as 19, so pretty tough for an average sorcerer to bind, and will do decent damage with POW based damage attacks. STR 18, CON 18, DEX 18 and INT 18 (equal to the sorcerer's POW), all other attributes are at 1/2 POW (ie SIZ 9, CHA 9).
As above, skills are as follows:
Attack and Dodge at DEX x 3%, Parry at STR x 3%, or 54%. All Perception skills at INT x 3%, so 54%. Not bad, it has a fighting chance.
Now for its powers. Guardians are supposed to have:
One Melee Offense - I roll 9, so just Claws doing 1D6
One Area Offense - I roll 5, so Sleep Attack. Very good for a guardian.
One Defence - I roll 3, so a Dust Cloud. I can see a sort of dreaming, sandman guardian here.
One Random - I roll 11, so it shoots Webbing. Better and better!
So, I see a tough but small guardian demon that can put Pcs to sleep, blind them with dust clouds, or bind them with webbing. Good stuff! Now I only need to decide what it looks like - a thin, whitish dream god with black hair and eyes, or a masked figure in suit and hat, or a spider.
Optional Table - Demon Appearance
If you have trouble coming up with the lesser demon appearance based on what you've rolled, you can always roll on this table for inspiration and tweak the results.
1 Human - Like us, but... different. A mockery of man.
2 Undead - Walking corpse, redolent of rot and decay.
3 Worm - Writhing and white, instantly revulsive.
4 Devil - Horned and barb-tailed, with neon red or blue skin.
5 Angelic - Beautiful and innocent looking, but with evil eyes.
6 Non-euclidean - Shape seems to change constantly, best not looked at directly.
7 Slime - Translucent and quivering, makes your primal brain cringe.
8 Flesh - Muscle, bone, and blood on display, unnerving.
9 Scaled horror - Some antediluvian thing crawled from the muck of ancient swamps.
10 Alien - Life not as we know it, btu evolved on some far planet under different stars.
4c) Greater Demons
Greater Demons, such as Stormbringer, can only be obtained by questing and are only obtainable if a Chaos Lord allows it. They ALWAYS have an ulterior motive, and so should only be offered in time of desperate need to force the players to choose.
1) How to Summon - These can only be summoned or bound by The Lords of Chaos, who may lend them to adventurers for their own purposes.
2) Attributes & Skills - As the GM deems fit.
3) Abilities - As the GM deems fit. Examples include draining 1D100 POW on a hit, Wardpact against certain weapons, etcetera.
4) Other Notes - A GM must never forget that such a demon, especially when converted, can only be beaten by great roleplaying.
