Already trying to figure it out by myself, here's what I've learn from tools Larian released:

1. decide where and how to summon something. defined by the skill's type,like summon(bone spider), target(bloat corpse) and projectile(the way Karen summon its minions).

2. what it will summons. Pick something or someone in Root Templates and create it in the scene and the position where you've already set.

3.decide its stats and set it as your "pet", which will make it benefit from your summoning ability.

And here's what I can't figure, why everything I summon is set to soul bond with me and a "follower", execpt those can't move at all, to always follow its master, and can't make a conversation with its master(or just one of my team member)?

I'm just trying to make a " Summon a merchant" mod, to sell trash and things I don't want on the journey to Divinity.Surely there's some way, I can feel it but just can't find it. :cry:

Any help or ideas are appreciated.
