You don't have to get all offended and snippy.

I often come off as snippy when I'm trying to make a joke. I apologize. Good advice in general: assume I'm not at all offended unless it's exceptionally clear and the context says I should be lol

hmmm... news to me! So I imagine it also protects from Plunders, but how about Massacre and Raze?

Plunders yes, not massacre or raze. Raze ignores many(most?)damage limitation mods.
