Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods [WIP] Boss Summons

So I have begun work on a mod where eventually bosses will drop a Skillbook that teaches a character how to Summon them for battle.

Right now I have just been focusing on getting a skill to summon Braccus Rex into the game. I have been able to add the skill by making a SkillData.txt for my mod and have it added to my character via SkillSet.txt at character creation. I can summon a Braccus Rex into battle.

There are several issues I could use some input on:
1. I'm not sure how to add a custom Skillbook (that teaches the skill) to an NPC's inventory. The plan is to eventually make Braccus Rex drop his own Skillbook, but for testing purposes I am wanting to add it to one of the Cyseal merchants.

2. The skill in the Skill bar has no text. There is no name, no description, no nothing. It's just a nameless spell that just says its Action Point cost and the cooldown. The descriptions in the SkillData.txt don't appear to have worked on their own; what other files do I need to modify for the skill text to show up?

3. The Braccus Rex I summon has no skills that he can use. As it is, he is just a really tanky juggernaut who can swing his axe. I'm wanting him to be able to use his Meteor Rain ability. Any thoughts on how I could add it to a custom summon?

Edit: Mod is well on its way to completion. I just need to make some tweaks to the values and skills of the associated summons. Check out the later posts in this thread for more information on them.
