Item ability stack + Increase level

[Nudl9]

I tried to add item bonus +1 agi with triggers but it didnt work, and i wanna know how to make it stack.
I also tried to make the spell have 30 levels and then increase it/set lvl + 1 too, but that didnt work either. It was always on level 1.

Now i need to way to add agility to this unit...

All you have to do is this:

• Add Agility
  • Events
    • "Your Events"
  • Conditions
    • "Your Conditions"
  • Actions
    • Hero - Modify Agility of "Your_Unit": Add 10

Just change the ones with "" around them to whatever you need.
