That multi-charm trick was fixed in the patch, but my shield is 4 slots, my armor is 5, my gloves are 5, my belt 2, my boots 3, my amulet 3 and my helmet 5.
I buy every silver charm I can get, and I got some cool gold charm drops in the orc camp. Plus most of my gear is from the dragon set, so I have a base 10 - 15 resistance on them. Plus I have level 4 magic barrier thingy :P that puts me at 20 resist without equip.
Let's say all my equip was clean, that's 27 slots for 4 elements, at 40 resist for a gold charm, that makes 240 resist per element + 20 base + about 30 from native equipment bonuses. So if I could remove my current charms and get the gold charms I wanted, I could maybe reach 300 resist all! <img src="/ubbthreads/images/graemlins/badsmile2.gif" alt="" />
