I'll wait to see if there is any other possible ways.
I'm also considering the necromancer's spell and it would look like that it's taking damage more.
can't you just set berserk's "increased damage taken" to a negative number? (You have to allow it in your WE and then shift click to make it negative). Thsi also works with damage reduction to a negative value to set it to increase damage. Just an idea for you there![]()
Rune?
That would be too much for an auto-cast ability. Especially when it's a caster unit.
I mean would that affect the map since a lot of them will be running at the same time.
