i have tested mine, he is not fully maxed yet so a little bit of attack is missing
summary he hits very hard, i am happy with him.
is he the hardest hitting fast hero in the game at the moment?
Elkanen with 1160 defense
Bonecrusher lvl 82 full with lvl 17lvl mana troop attack
No buffs or debuffs
34def debuff
finley 56% def debuff
48% attack from boldtusk
with 48% attack buff, 20% attack passive, %15 attack on weaker element buff and finley 56% def debuff
fully maxed higher troop more than 2k damage seem feasible.
