Does the skill have a skill set in the AiCalculationSkillOverride column? Ai doesn't know what to do with summoning skills unless you set a skill in this column. It's unclear to the Ai what kind of effect the skill has, and the skill override is used to simulate the effect of the summon. This skill override has to be of the Target type. A skill that's often used for the override in other summoning skills is Target_DummyTargetSkill. This one does physical damage in a radius to simulate a summon that does physical damage. Other, already existing, skills you could use are:
- Target_DummyTargetSkill_Fire (fire damage)
- Target_DummyTargetSkill_Water (water damage)
- Target_DummyTargetSkill_Air (air damage)
- Target_DummyTargetSkill_Earth (earth damage)
You can of course make your own skill as well. Some more information can be found right here:https://docs.larian.game/Combat_AI#Skill_overrides
I hope this will help you!
