[Cerek the Barbaric]

After charging after these things and battling them with melee' weapons (and suffering the effects of the noxious Cloud for my efforts), I found an exceptionally easy way to kill them.

Just purchase the Reflection Shield from Diedra in the Adventurer's Mart (bonus merchant CD or download).

I was fighting the first Adamantium Golem in the Planar Sphere and getting beaten up badly because I didn't have many weapons that would even hit it. Then I remembered this shield I had purchased and given to Jaheira.

So I did a quick re-load and sent Jaheira ahead of the party to face the golem by herself. As soon as it saw her, it started throwing boulders (since it was too big to fit through the doorway to advance any closer). Jaheira didn't have to do a thing but stand there as the boulders were Reflected by the Shield back at the golem (doing anywhere from 2-4 hit points per hit). Naturally, it took quite a while to kill the golem this way, but Jaheira was far enough away to avoid it's Cloud attack and the rest of the party just sat back and watched as the golem slowly - but surely - killed itself.

I used this same strategy on the lower level of the Sphere. Jaheira killed every golem down there singlehandedly. Her Gauntlets of Ogre Power, Sling +2, and Bullets +2 made very short work of the Stone Golems (avg 14-15 hp per hit). Meanwhile, the Adamantium Golems took care of themselves once again.
