What would the benefit of being Thri Keen be if he can't even wear most items?
They make great clerics or druids thanks to high WIS. They have 4 unarmed attacks, which would be awesome if they didn't become useless a third of the way in. And he can only carry two weapons anyway, so meh. The extra acid attack is unaffected by carrying weapons and is quite nice, but not nice enough to compensate for shitty AC. And if you want high WIS, halfling's is even higher.
Seems like Half Giant would be the best Gladiator or Fighter ever.
Yes. Huge strength and huge amount of hit points and are not be sneezed at high a warrior class.
Should I even bother multiclassing him with Cleric etc?
No. Clerics suck anyway in Dark Sun, as they have no access to the Cosmos sphere beyond 3rd level spells (so no Neutralize Poison, or Cure Serious/Critical, etc). Druids do, and they're a much better choice as a divine spellcaster.
Hell no. Psionicists are possibly the most powerful class in the game. The kinetic stuff is a bit shit, metabolics have some useful powers, telepathics are horribly overpowered. Synaptic Static will prevent EVERYONE from casting psionics and is a great help in Dagolar's lair and the final battle, then there's all the domination powers (Mass Domination can turn a tough battle into a cakewalk with one click). And finally you sometimes get to solve some quests/obstacles differently by getting to use a psionic power during dialog.
Too many to list. Your party sucks ass. However the game's easy enough, and as long as you have that Preserver you'll be fine. Backstabbing works similarly to the Gold Box games and is insanely powerful at high level, so keep that in mind.
Also, is there any THAC0 penalty for dual wielding? I can't seem to find the info anywhere.
Not as far as I know, or ever found out.
Have fun. Do let us know how it turns out, though I don't think you'll have much trouble (or any kind of trouble until the final fight, really, and this party might be just the thing for the final fight)
