Spell resist rate and how to lower it?

[rixardion]

I'm a lvl 30 ench.
I've noticed resists seem to be much more frequent than when I played before.
Dark blue mobs still resist me after tash up to 3 times in a row in some cases.
I remember resisting being almost non-existent after tash for a dark blue mob with few exceptions.

My question is how can I change this? Is there a stat I need to focus on? Does charisma dictate resist rate of all spells or just charms? I'm having a hard time believing there is nothing I can do to decrease resist rates.
