Keep in mind: one of the points of golems is to be big. Making them smaller significantly gimps their usefulness.TheGogmagog said:So how much for a dimutive iron golem?
I've always wanted one to stand guard at night: damage reduction 10/adamantine, darkvision 60 ft., immunity to magic, and no need to sleep.
If you really wanted a diminutive iron golem, I'd say (off the top of my head) it would have about 5 hp; 9 Str and 13 Dex; DR 1/adamantine; a breath weapon that does no initial damage, 1 Con secondary damage, and covers a 5' square to a height of 1'; darkvision 30'; immune to magic (it is still a golem after all); and a CR that doesn't even rank. Four of them might be a CR 1. Oh, and it would cost about 25,000 gp.
Not remotely worth it. There are much better constructs of that size you can make for cheaper.
