Activate Mana Deflector?!

Was in Par and decided to see what my r9 gold strike would do against the snow zombies. It pinged. They flashed blue. So the skill is actually considered a magic effect by the game, or is there another explanation?

That confirms it activating Mana Deflector, but there is a possibility it is effected by multiple passive defenses. Either way, that should be added to the page.

It doesn't necessarily mean its magical. For instance, Rock Throwing also pings blue but it contributes to Ranged Attack training.
