Yup it's less annoying than the dam haste Arkam >_>
Tho i think it does have the advantage of knocking down... which slime can do a fine job.
I think the only reason to do that gacha dungeon is for the freaking haxxxxxxx set bonus...
"◦Wearing the full Dusk Wing armor set bestows a special effect on the wearer that increases HP regeneration rate (PvP only), reduces MP lost by counterattack, and increases defense by 10%"
And by "Reduces MP lost by counterattack" i bet it's the same as castlelord set aka 0 MP >_>
