He's got the highest fill rate buff in the game, status clearing, kinda-nuke SBB, Fire Barrier, and ATK>DEF conversion. I'd say that's pretty strong already.

Tilith might have massive support, but her BB cost is way higher than other units, and her SBB cost is ridiculous. That doesn't even mention the fact that she won't be contributing to damage.

Tilith's UBB might have a ridiculous multiplier, 2 turn damage reduction, revive, and massive hit count, but Kryuk has a 3 turn damage reduction, a relatively high UBB multiplier, and the highest group HP boost (Korzan's self HP buff doesn't count). The status on his UBB can come in handy too.

The main thing about Kryuk for me is his LS, which makes your units practically invincible at half health or below, especially if you have ignore DEF ignore ESs or Darvanshel friend/lead.
