Hmm, but it does have the odd bit about fire and electricity spells.
Here's a question: do most object-affecting spells allow SR?
My two bits...
Despite the original writeup, the "greater" version has alot of HD, and is clearly healed by fire, so I'm content to just give 'em the standard immunity to magic with healed by fire. We can work some sort of electricity response in as well (maybe negates DR like many golems vulnerabilities?).
I'd be fine just leaving it off for the "lesser" version, and maybe retain a "healed by fire" and/or "weakened/repelled by electricity" SQ.
I still prefer to leave in Immunity to Magic. I don't see anything in the construct type that says it would not be affected by spells that affect living targets, just spells that are mind-affecting or allow a Fort save (not affecting objects). There are spells that affect living targets but don't allow Fort saves, surely. Word of Chaos, for example, affects living creatures but also must affect inevitables.
Negating DR for electricity damage would work for me well enough. Or slowing. Either is better than the vague backing away of the original monster.
I strongly dislike SR for 'em. I'll let you two debate the merits of other approaches.![]()
For the 'Repulsed by Electricity' SQ, how about if they're hit for electrical damage their "circuits go haywire" and they must succeed at a Fort save or be forced to move (costing a normal move action) in a random direction that turn?
That does sound fun...
