ToME: the Tales of Maj'Eyal

Playing as an alchemist, when I try to refit my golem to equip him with a new weapon/armor, and I press control to compare the new weapon/armor with his current one, I instead get a comparison with my OWN weapon/armor...

You can drop the weapon, switch control to your golem (right-click it, or left-click its portrait in your allies section), pick it up, and compare from the golem's inventory. You can also do this to equip your golem with a shield and one-hander.

Oh, cool - I just figured the golem was unable to equip one-handed weapons! Maybe the refit command should be dropped, since it's relatively useless at this point...

Refit still has to be used to put gems on your golem, and you can also use it for the rename function. It also heals the golem for a fair amount, and is your only way to resurrect it until you get Supercharge Golem.

"Put gems on your golem"? Hmm, I never saw any such option...

The option opens up once you've invested points into gem golem, the second tier advanced golemancy talent.
