Mustard Jellies, Magma Mephits, and You

Endarire

Greetings, all!

I'm using Sword Coast Stratagems 28. I was in Chateau Irenicus, facing the Mephit Room. I used Polymorph Self to become a Mustard Jelly. I assumed I'd be fully magic immune, but the magma balls from the Magma Mephits still damaged me.

Considering that in BG1, spell resistance negated energy damage (like from Arrows of Flame), why did I get hurt?

Uninstall SCS and try again. If the same thing happens, ask your question again in General Discussion (Spoiler Warning!). If removing SCS causes the magma balls to be resisted, ask your question again in Sword Coast Stratagems is now available for BG:EE and BGII:EE.

I think this is correct behaviour. The magma balls should be breath weapon so no MR applies. At least in PnP...
