Apologies if this question has already been asked. If so, just point me at the thread and I'll go on my way.
I know how to increase the max hero level beyond 10 in a custom map. Once I've done that- let's say to level 20, as an example- if I want the max ability levels for all existing hero abilities to remain as their default values (3 for the first three, 1 for the ultimate) and I simply want to add a ten level "Learn Attribute Bonus" Ability for all heroes that mirrors Rexxar's ability in the Founding of Durotar, how would I go about doing that?
