Name: Sara, the Scarlet Maiden
Faction/Purity: 1 Sleepers of Avarrach, 1 Exiles
Type: Unique Character - Demon, Undead
Infect, Consume 5
Each time a Character is killed, Sara gains a stack of Bloodrage which grants her additional abilities for reaching certain stacks. Sara can only access these abilities while deployed.
[Up to 3 stacks: Once per turn, you can pay 1 resource to move a Character your opponent controls to the Assault or Defense Zone of your own choosing.
Up to 5 stacks: Sara permanently gains Unstoppable and heals herself to full health at the end of each turn.
Up to 10 stacks: Once per turn, you can pay 4 resources to grant Sara invulnerability to all other card effects until the end of the turn.]
"Fleeing to the Wastes after Veroria's destruction, Sara found herself at the mercy of a stray Avarrach virus infection and the torturous game of hide-and-seek the demons played with her. As the last of her humanity was overtaken by the virus and the demonic corruption, she turned into a monster who only hungered for the taste of blood and the thrill of the hunt."
Clarification with her additional abilities:
They are cumulative and show up like Agent Zomborg's although she needs to be in play such as the Command or somehow stuck in deploy to have it work.
She will still be affected by card effects that occur at the end of the turn such as Tome of the Dead, Track (and Hunt which occurs at the end of a different turn entirely), poison/immolation effects, Descent into Madness's removal, Demonic Corruption's stat adjustments, etc.
EDIT: Increased stats. I forgot she wasn't in Verore so no surprise Word of Command unless in a rainbow deck.
EDIT2: Reworked to be less dependent on abilities (Chaos in the Ranks, Vigil, Word of Command, Unstoppable, Hehkeem, Fight!, Second Wind, etc etc.) and more self-sufficient. Increased cost, increased stats, increased morale. Stylized to be more like a vampire slowly succumbing to a blood frenzy. Considered card's concept to allow for a beatstick in dual purity deck as opposed to rainbow purity decks. (Sleepers have relatively little to no high-powered cards barring Zomborg who takes time.)
