Dungeon Fighter (Second Edition): Betty Loudscream Promo Hero

A Kickstarter-exclusive Hero. This "vampire metal queen" has a chilling self-healing skill: her "Blood Donation" ability allows her to "kindly ask" one of her teammates to "willingly donate" some of their life energy to her. Card text: before a fight, Betty can force one of the other party members to lose 1 HP; if she does, she will gain 2 HP in return.
