One question here. the shaa sword on an act 3 merc reduces the physical resistance of mobs around by 20%. Is this also with 1/5 penatly and only uses -4% on physical immune mobs? Would be useless too then... If not, try this sword
Also one more question @Game :
Ravens are considered pets, so they dont benefit from characters -x% enemy physical resist, or? They are not affected by auras (like fanacitism), or am i wrong?
