Yes, unless u are killing the enemy, its meant to use when thye have 0 armor to inflict bleeding, poison coating doesnt lightly hit. I do 2.2k physical + 2.4k magical damage on mortal blow, cuz of runes+coated+poison, and sawtooth gets all that damage, sums, and deal all as piercing.
Also, destroying magic armor lets you sleep ppl, and allies can do stuff too.
Bout adrenaline, i think its good, but not that much... Its good for combos and to burst ppl, but i hate having -2 ap next turn.
Wind up toy is meant for summoners only like almost all summons..
