Ran back the tests to be sure.

Tried to proc Guard Dog against Godray Undertow, Chariot Star, Light On High, and Rising Dawn ~30 times each with a level 60 Kerberos install, but only Rising Dawn triggered Guard Dog. It was done it a corner to prevent movement just in case, but 0 procs happened.

I'm at a bit of a loss, but unless I'm getting cosmically unlucky, something isn't right.

Additional tests (10 attempts):

Raijinken: 0/10 procs
Wazabane: 4/10 procs
Cyclone Spear: 0/10 procs
Lance de Lion: 0/10 procs
Eclaire Lacroix: 0/10 procs

Looks more like it isn't working on non-basic attack skills at all.
