By "Trait attacks" I refer to ones like, Magic Doll - Grappler, Folrart Elite Dual-Wielder, Bog Wyvern type attacks. Where the attack action is replaced with something different.
Me and Snik did some testing and found a pretty big inconsistency. We were testing both whether Beast King / Rivera SS boosted these kinds of attacks, and if they can hit units such as Feline Kin Fighter, that can't be hit with an Attack option.
What we found was that Magic Doll Grappler can hit Feline Kin (ranked up of course) and does not get a boost from Rivera. In other words, it was not treated as an attack. On the other hand, Dual Wield and Bog Wyvern can not hit Feline Kin and do in fact get the boost. So, those one are treated as attacks.
Now, compare the wording of Grappler and Dual Wield's traits:
Grappler: "When this unit executes an Attack action, subtract AT directly from the HP of one random enemy unit within range."
Dual Wield: "When this unit executes an Attack action, do [damage: AT] to two random enemy units in range. Remains after Revive."
So, i'm just wondering whether or not this is an error, and if so which one is right... or if there is something distinctly different between the two. My only thought is that grappler is a subtract effect while dual wield is still a "damage" effect. Could that be the difference?
