The fight with pirates Options

[Aro]

Hi all.

I want some help with these guys in the tavern at the Docks. They are very tough. My party is:

Vagrant PC with proficiency in clubs and uses the +3 acid one from Trademeet
Valygar
Anomen
Jan Jansen
Edwin

Jan and Edwin can cast only 5 lvl spells and less.

That mage casts Remove Magic and emotion and abi-dalzim, and my characters die very quickly. The captain I cannot kill, he's scary. Help! My fighters deal very small damage to him.

I want another party member, but all NPCs are so weak. Any recommendation?

And where to find a permanency scroll or manual of elaboration or scroll of memory? I want a scroll for the club +4. It costs 50 000, is it worth it?

What weapons to buy?

I don't know about another warrior in this party. Other characters will level up slower. And those pure classes do not have stoneskin and mirror image. Maybe the cleric-illusionist will help with thac0? I was thinking about chant and bless spells in minor sequencer. And my party leader has two strength increase special abilities.

Will Champion Strength be of any use? It gives very good bonus to thac0.

Will I need hardiness for these characters? I decided to go with spells for protection. And the greater whirlwind looks nice, but how about just improved haste?

I want to have Laloch minor drain, Skull trap, spirit armor, vampiric touch, hand of undoing and abi-dalzim in sorcerer spell picks. I read that anti golem spells are very good and decided to take the hand right away when my sorcerer can cast 7 lvl spells. Should I wait and pick another one?
