Deal with the Devil悪魔の契約
Sacrifices X% of HP for +2 to ATK (on straight+, +2 to ATK for party)自分のHPを犠牲にして、攻撃力を上昇させる(ストレート以上の時、味方の攻撃力も上昇させる)
When main card is A, boosts main card's damage by 35% and increases damage received at all times by 15%親分がAのとき、与ダメージを35%UPするが被ダメージが常に15%UP
|バフォメット, Basilisk, ヘルハウンド|
With the highly aggressive nature of the game (bosses can frequently be killed in one turn with the right set up of cards, especially at lower difficulties), sacrificing a decreasingly small amount of HP (the amount required decreases with skill level) looks like a better and better proposition in exchange for broad offensive power. This is especially true as it's quite possible to play Baphomet early, heal off the damage, and enjoy the party-wide power increase.
Buffing cards can often be hard to place, and while Baphomet may struggle to place as easily as Eru, his ability is also more reliable as it reaches 2 naturally unlike Eru- this makes a bigger difference than it might seem as getting skill enhancement for buffing cards is extremely difficult. For a player whose interest is primarily in offensive burn-down rushes, the increased attack power will likely be well worth the small HP loss. Not a card for everyone, though.
While not quite at a +3 naturally, any 15% or better boost will push Baphomet over into +3 territory at SL7 which is absolutely fantastic. The main deal here is that at SL6-7, you absolutely have to make a concession with your team by guarantee-ing him into a straight+ hand, which doesn't always happen (and if you end up pairing off, you're still eating the HP cost for a boost on yourself only). Baphomet is also one of the various cards that can activate the likes of Xebec and Cronos (At SL6-7), so there's definitely some value to be had in that as well.
At first, this demon's deal might seem like an attractive subskill, but you'll often find yourself in this game enough damage to put you a sliver's away from death in PVE. When looking at this subskill, consider every time you've encountered those moments, and remember that if you had Baphomet equipped then, you would have died instead. If you could reliably play your ace all the time, this might be different, but especially as aces often fit poorly into hands (as they can only be the end of a straight, not the middle) you'll end up taking a lot of damage for never playing a single ace.
