Ability upgrade

[DexterFstone]

Hi
I have 2 ability (ability1, ability1 upgrade)
and one ability for change ability1 to ability1 upgrade (passive ability), now my question is how to change ability1 to ability1 upgrade with my passive ability? (I'm using attribute bonus for change ability1 to ability1 upgrade)

I use Unit - Add Ability but it does not work

Check out Tinker's Engineering Upgrade ability, it should do what you need. I think it's bugged in Reforged though, so keep that in mind if it doesn't work.

Use native functions( BlzSetAbilityIntegerField, BlzSetabililityRealField,BlzSetAbilityBooleanField,....) to upgrade/downgrade whatever ability you want
