It dont work... i used to use an alternative way ok lets start first u make all char that can give reflect dmg buff then u must buy a pet (like buffalo etc...) u make alla the reflect buffs and all buffs that make it lose p.def like berserker take the buffers with u and some rez go on rb and buff it with all buffs that gives patk (like might,g might not forget to do berserker) then attack the rb with the pet..when the pet dies rez it and rebuff and so on.... i used to kill 1 rb in 20 mins in c3,c4 i dont know if it still works.... if anybody try it just let me know
