it's not much of a challenge. u just need to avoid doing stupid things like attacking when ur enemy uses reflect/stun immune. just buy lotsa unique items (orange colour) and u shuld be fine.
this game actually requires skill. u have to keep one eye on all ur enemies skills and one eye on his cast bar and then use ur skills. lol. i find it easier at the start of the battle to pick out 1 or 2 skills that i definitely have to interrupt, then just focus and wait for the enemy to use it and then interrupt and make sure he uses up his interrupts b4 using any major skills of my own.
