Energy Vulnerabilty Spell vs. Immunity

[Drowbane]

Energy Vulnerability + Immunity = 0.

However, aren't there a couple feats (metamagic) that allow you to damage creatures normally immune to that type of damage? One for both cold and fire... IIRC.

So...

Energy Vulnerability + Metamagic feat Fire (assuming I'm not dreaming here ) vs Immunity = 75% fire damage vs a creature that is immune?

Not too bad... if you couldn't just blast around it with another energy all together.

I believe the name of the metamagic feat is Searing Spell. Your calculations are indeed correct.
