Some changes i have for ur guide..
i think for ur items, u dont need to get mara in mf run, jus get max mf magic ammy, also wear ali ba ba (get many dex sc).
Also, for ur stats thingy, i jus noticed, u dont ned to put any for dex, all sorc has to do is tele/river meph to avoid attacks. besides, u'll need act 2 freezing merc (very good tanker) for pindle, other wise you'll jus die off quickly. Also, you dont need inferno, its only fire dmg per second, with resistance that meph has, it will reduce the burning dmg huge! Learn static/frozen orb.
Otherwise, the guide is perfect
