Okay I'll ditch the Chausable, and I guess move some skill points into concentration as well. Wasn't too worried about it because in a few levels I'll have an invisbility spell to use
Hiya, I've been RPGing for years & have found the Warlock to be a lot of fun & helpful in most situations.
Specifically for you to think about...
Why ditch the Chasuble? I didn't see a reason given - maybe for an
amulet of Natural Armour...?...or perhaps drop your leather armour
instead, & get yourself some magical elvin chain - because it's made
from mithral, it counts as light armour - so you can wear it...
As for Invisibility...dude - don't count on it protecting you too much...
At higher levels, many monsters can see invisibility...it's screwed our
mage on more than one occasion - as that's his favourite trick... ; )
So - back to the above paragraph - invest in some good magical armour
& a ring of protection. (At Lvl 12, you should have WAY more magical
stuff than you have listed...
Hope this helps.
