From what I see, enemies can have quite high intelligence later on. If they were able to control you, no matter how much you invest in BB or WP, there would be a problem.
True.
I'm also glad they don't have the same number of skills and the same intelligence as main caracters . The game would not be playable at all ^^
Now I know that I guess I'll increase WP and BB... well... it might be to late at level 19 but I've made it this far.
I assume Witchcraft is by far the best magic in the game with the "Drain Willpower" ability.
I, honestly, would not have made it this far if I couldn't Drain WP + Blitzbolt + Petrifying touch to keep an enemy disabled for 3 turns... since even basic enemies can melt down any of my Lone Wolves with only one full turn.
Anyway thanks for the replies, it seems I need to stick to Loremaster 5 to know who or what I can CC.
