RED micro-site now out!

Probably not. when Dark Knights fight mobs or bosses with cross over chains active, their hp generates right back to 100%

the same may apply for demon avenger, but once they hit 20 times you can see that it starts to decrease. That doesn't happen with Dark Knights, their hp is pretty much always at 100% when fighting.

I was actually more concerned about Phantom than DrK, but I suppose a lucky red card proc can mitigate the loss of HP.
