Some masive + to AR. After going through Act5 on NM i picked up a rare repeating crossbow. Ok at the time i was lvl 58 and this bow had 2 mods based on level. The frist one was +AR based on level, at 58 it gave me +924 to AR. the next was to max damage, and i was getting +28. It also had @99% damage to demons and +253AR to demons.
