Just wear occy and tals belt and have positive resists...I was level 73 and did well against meph and pindle....Block helps but it isnt really needed. Also wear perfect maras. My friends sorc is just like your except he uses occy and perfect maras. Or why not just wear tals set. except the mask and orb.
EDIT: Titus hook me up with a lil sumtin sumtin s(._.V hehe
