After looking into it some more the "Doom" (Enrage) effect seems to be working properly.
e.g. Doom Club
Successful ATK #1, 11 DMG (10 Base, +1 Enrage)
Successful ATK #2, 12 DMG (10 Base, +1 Enrage, +1 Cumulated Enrage)
Successful ATK #3 13 DMG (10 Base, +1 Enrage, +2 Cumulated Enrage)
and so on.
Note that the bonus doesn't apply to Counterattacks.
it is not working in the second scenario of Fallen Enchantress (the one that plays like a normal map; the "second campaign")
I've tested it with two different types of doom maul - the one that came from research, and one i found randomly that does less damage.
not. working.
are you sure you didn't already modify the settings in yours?
