So first things first... The tool tip on Health Transfusion says it will do damage to my pet for 10% of its maximum health and heal Plaguebringer for 300% of the damage dealt. So for my tank that should be 1293 damage and 5172 healing for PB. Only it didn't work like that... My tank was damaged for 1293 but PB got healed for 6465 which is 400%... So either the tool tip or the move should be fixed?

Another weird thing... PB killed my tank - and then she brought herself back to life with siphon? I'm not complaining by any means, I think that's awesome, but is it supposed to work like that?

It's actually 500%. I'll adjust the tooltip.

1293 * 5 = 6465, so the mechanic is working correctly. The tooltip is just wrong. Most likely, as I was creating the battle and tweaking numbers, I adjusted the value and forgot to adjust the tooltip.

As for siphon, yes, that's mostly intended. While it wasn't originally planned, when we discovered it we decided to leave it in game as a shout out to the "purple club" from Everquest. If you never played Everquest, basically, you could go a little bit into negative health and were considered unconscious and your health bar turned purple. Until you reached -100 health, you could be revived from health regen or heals.

Oooh yeah 500%, 400% increase... Thanks!

And that is really fantastic news... My tank should have been dark from the beginning!!
