"Can't Touch This"

I was wondering if anyone had checked out the limits of this skill and places where it does and does not work.

For instance, hopping vampires and unstable ooze explosions?

I know it can stop Twisting Jaws from dinosaurs.

The touchers in duncan and selves dungeons. Incubus that use shock as well, I think.

Doesn't work on Dhuum for whatever reason.

It works against Moss Scarabs in the Maguuma, and I find it extremely helpful when doing The Wilds mission in HM, since the early areas are just swarming with those things. Likewise it's handy against Jade Scarabs in the Crystal Desert.

unstable ooze explosions?

It should work on this.

I'm just wondering since there's actually quite a few places where touch skills result in deaths and wipes.

Ooze Pit in HM with 7H can be tough, and Urgoz is never an easy affair.
