3 max dmg--> 38dmg finally (i tested it )
so 170 maxdmg would add finally 2153.3333 maxdmg
thats 1+k average dmg/hit !!!

zeal+fana+ed stuff makes for me more than 1k%ed =)
(dmg from sc's*12,66!!!!)

hm, and if there are some nice @'s on the charm, like +skills (kk than maxdmg would be the @)
or str!!!!!! than u even got more dmg, or life or whatever....

so i think it's worth.... ;but just my thought;
