(CB and dungeons) mid game 2 key brutal, still without a decent poisoner (pulled kael very late so used 2 sacred monks)

option 1: kael who is only 1 book away from decreasing the cool down on A3 easiest, a little boring but soon outclassed by a fully booked frozen banshee

option 2: frozen banshee-arguably new best poisoner but she's very weak without a3 booked, won't lay the poisons. and may also require a debuff extender which i lack out of rare books, so as a cheap to play, will take me a month or two to get them.

option 3: corpse collector-seems overlooked, but fully booked has 100% chance to place 3x5% poisons every 4 turns, which competes with kael and gives a bit of affinity diversity.  also better HP and defense than kael.  i have the books to fully book her, but might be a waste of epic books (i was hoping to use them on sepulcher sentinel to bring an extra attack down to by tanky defense clan boss team)

thanks for looking
