How do I do it so that when a hero meets a certain condition (i.e. kills a boss) one of their abilities gets slightly better like in DotA's Aghanim's Sceptre. I've tried this but it doesn't remove the first skill.
Trigger:
- Actions
- Set Temp_Integer = (Level of First_Skill for Hero)
- Unit - Remove First_Skill from Hero
- Unit - Add New_Skill to Hero
- Unit - Set level of New_Skill for Hero to Temp_Integer
- Set Temp_Integer = 0
