Demon summoning program

you are able to build a Gauntlet called a COMP that has the power to summon creatures from a Plane called the expanse with a Program called the Demon Summoning Program
Using this they can store and summon demons that they’ve acquired through negotiation or fusion. In negotiation the Demon Buster can try to convince a Demon to join their party. This is done by making a successful Persuasion, or Intimidate check (the one used is up to the GM). The DC of this check is 10+1-5 (the 1-5 is determined by the GM based on circumstances such as whether or not the Demon Summoner has been actively aggressive prior to the negotiation. Once the negotiation has started successfully, the GM may choose whether the Demon has additional criteria that needs to be met. This could include things like a second negotiation roll with a higher DC, a role-playing scenario, or the Demon may ask for an item before it joins the party. If a demon asks for money or an item After a demon is recruited it will join your party (if there is an opening) or join your stock. Once a demon is added to your party or stock it is immediately uploaded into your compendium. A demon stored in the compendium can be summoned again in a process that takes one minute and costs 5gp per challenge rating, you can have up to 4 demons in a party .

Demon whisper

At 5th, A Demon Buster is able to replicate the abilities and spells used by Demons. However, this requires a demon to willingly teach the skill to it’s Summoner. Anytime that a Demon in the Busters’ party or stock would form a bond with the Summoner, the Demon can choose to impart any of it’s skills onto the Demon Buster. The Demon Buster may now add that skill to their list of skills they can perform. The Skill Starts off at Rank 1 and anything that would result in gaining this skill an additional time will increase this skill’s rank by 1 (up to a maximum of 5). A Demon Buster may only have up to four skills at one time before they need to replace a skill in order to learn a new one , you have to use Mp (magic Points) to use skills that the demons teach and at you have base mp that increase as you get more Demon Buster features and get gain it all back at a long rest and half at a short rest.

Elemental favoritism

At 9th level , choose one Demon Skill type (Physical, Fire, Ice, Electric, Force, Light, Dark, Support, Healing, or Almighty) all Demon Skills of this type start off one rank higher than normal for the Demon Buster. When you get this ability you can choose a Demon Skill type that you have already increased, or select a new type. Also you now summon demons of a CR equal to half your Bonded level, rounded down, ignoring the Max CR column of the demon contact table.

Fusion

At 15th level ,It is now possible to fuse multiple demons together with the fusion Program in order to create completely new demons. however most demons are fused by determining the CR of both demons and then determining what challenge rating encounter that would be. This becomes the highest Cr demon that can be fused using those materials. A Demon Buster is unable to fuse a demon that has more Cr or levels than the Demon Buster.. When a demon is fused, the Demon Buster can choose which Demon Skills it is created with by selecting those Demon Skills from a pool comprised of the Demon Skills that demon has naturally, as well as the Demon Skills possessed by the two (or more in some circumstances) demons that went into fusing that Demon. A demon cannot have more than four Demon Skills (excluding extra Demon
Skills slots from Apps) and any multiple instances of the same Demon Skill will increase the rank of that Demon Skill by 1 for each instance of this happening.
