im probably wrong BUT. +10 Quad drainliar mace dmg = 57 x .8 = 102.6 dmg [thats with the +10 bonus on lvl 1]
and a +8 wind Fist dmg = 117? x 1.75 = 321.75 dmg [not sure on dmg of fists and its upgrade bonus. so its a bit off.]
the .8 on the mace is the drainliar cards cause they stack and you dont get the elemental advantage from using a fist. because its still a neutral weapon. As for the Wind fist u get the 1.75 from the elemental advantage from using a wind property over water. please correct if im wrong. ^o^. just tryin' to help
edit - i also did not add any other bonuses like megs or the str stat point. just a basis i guess.
