Searing spell 3.5 sandatorm

[CMagnum]

My player has searing spell meta magic from sandstorm. It deals normal damage vs creatures with fire resistance, and half damage vs creatures with fire immunity. How would it effect the unique properties of a an iron golem?

Calculate full fire damage as if the save (if any) was failed, cut the damage into thirds, apply one third as healing to the iron golem.

Searing Spell does nothing to avoid or negate Magic Immunity, therefore to the iron golem the spell is just another source of magical fire damage, which feels great.

Thanks, that was my original ruling.
The iron golem had been hit also with an electricity attack, so I ruled it was also no longer slowed as well
