[3.5] Boosting SR For Monsters

[Thurbane]

So, I was looking for some easy(ish) methods to boost the SR on a creature.

As the DM, I can always just hand wave an increase, but I prefer to follow RAW methods where I can.

I've done some searching, but the methods I've found are less than ideal (Boosting Spell Resistance for instance).

If it helps, the creature in question is a Ghirrash (outsider, 7 HD, SR 14).

• Awaken Spell Resistance feat won't work because it's not a dragon (unless I slap the half-dragon template on it?)
• Boost Spell Resistance feat gives +2 (if the creature is evil). One of the better options, but I'm hoping to poush higher than +2.
• Exalted Spell Resistance feat gives +4 SR, but only against evil spells and such; also not applicable for a villain.
• Daazzix's Vest (item) increases innate SR by +5, but a 25,000gp item would be utter overkill for this encounter

...is there any templates that would help? Preferably without driving CR up through the roof.

Cheers - T

You could have the Ghirrash take Shape Soulmeld: Spellward Shirt and Bonus Essentia. Then, if it invests both points of essentia in the Shirt, it has SR 18. It's less a boost and more of a replacement, but the end result is that the Ghirrash has higher SR.

Spellwarped Creature from MMIII would give a better spell resistance of 18, and would also provide some benefits when a spell fails to penetrate. CR increase is only 1 for the Ghirrash, and you could then throw on the methods you mentioned if you want a higher one.

Voidmind Creature gets SR 10+HD for +1 CR

Doesn't most SR follow a simple 10 or 11 plus Hit Die model? Couldn't you just advance the critter via HD to up it?

Thanks for the heads up. I don't generally use MoI in my games, but I'll look into it.

Unfortunately Spellwarped can't be applied to Outsiders.

That looks like a solid option for CR +1. Thank you.

While many (most?) creatures do follow this formula, it is not universal.

Also, SR doesn't increase by HD unless specifically stated to do so. I could DM hand-wave it, but I'd rather not.
