I want to create a skill like Inner Fire capable of being auto-cast but modified, I want it to be a skill that instead of increasing damage and armor increases all the hero's attributes, level 1 increasing the attributes by 3, level 2 by 6 and level 3 increasing by 9, with a duration of 30 seconds and costing 50 mana, as far as I know without using triggers it is not possible to do.
