These first four options are just informative, but feel free to vote for them anyway if you think one part of her skillset is particularly relevant. Eldritch Lore: As a high ranking priestess of the Healing Church, Imposter Iosefka has been trained in the use of special tools that allow her to summon giant tentacles from her hand or fire a barrage of glowing motes of exploding energy.
Threaded Cane Combat: The threaded cane is an objectively stupid weapon, so one can only imagine how much strength and agility someone needs to be able to effectively use a stick that transforms into a bladed whip effectively against beings 5x your size. Obviously, this comes with a free threaded cane.
Blood Ministration: Her body has been enhanced with a transfusion of blood found in a fucking abandoned ruin somewhere. This enhanced her physical capabilities, senses, and ability to recover from injury. She can also heal by consuming the blood of those tainted by Eldritch beings, or Eldritch beings themselves. (Injections work even better, though, and don’t worry about blood types) Note: the biggest issues with ministration will not manifest. If you know you know.
“Medical” Knowledge: Fun fact! Imposter Iosefka doesn’t have the Healer or even the Doctor tag. The medical field exists for research, nothing more. If she gets raw materials she can do some fucked up shit and might even be able to do some remotely ethical things too!
Full swap with Gil. Extreme superhuman agility and a few magical abilities is a great core skillset.
Blood Ministration for Gil: superior healing + massively boosted reflexes and agility is good all on its own
Full Swap with Keilnei: She will lose the blessing of the naaru, but otherwise she will become drastically faster, stronger, and more deadly in close quarters.
Eldritch Lore for Keilnei: gives her a few more mid to long range options, separate from her gun. Also MIGHT let her establish a stronger connection to the Naaru using the same techniques, turning her into a much stronger field medic who doesn’t need overt ambient magic.
Threaded Cane for Keilnei: She’s already perfectly adequate at mid to long range and slightly superhuman. This will bring her up to an elite level in close quarters instead of merely “a combat veteran”
Full swap with Charlotte. Superhuman abilities granted by a connection to a powerful eldritch entity, acquired after a traumatic event? That’s just a trigger event with a 3 day delay. Also… she might find herself getting ideas if she ever sees Powers in a Can.
Full Swap with Mei. Almost certainly enough to let Mei sub in for Noa. Useful if we want passive income while kidnapping Noa for ourselves. Also gives her a knowledge base needed to study and experiment with mist/seru if she can be persuaded to try it.
Full Swap with Magwin, the female night elf working with Ireena. She’s already just shy of equal to Keilnei in a straight fight, but she could be much stronger
Full Swap with Cowlin, the male night elf working with Ireena. Can’t be having mostly noncombatant dudes in our retinue.
Full swap with Boulder. Imposter Iosefka isn’t quite as attractive as Berelaine, but is a much better individual to always have “on tap”
Blood ministration for Blackpaw: His entire plan is ATACK. Giving him boosted strength and speed and the ability to heal by drinking magic infused blood just makes him better at it.
Full Swap for Nessa: Don’t change her look, naturally. This is a moderate reduction in overall power, since Nessa will stop being a part time Kaiju, but it will make her much easier to use in Brockton or enclosed spaces, she will keep her Symbiote, and Gil will be able to get 10 credits, Martial Talent, and Body Tune up out of the deal. Body Tune up might also fix Flashbang.
Full Swap for Terra: 5 credits, an Angel character card isn’t as big a payout with Nessa, but it does mean Terra will be able to walk her own ass around without a bearer.
Full Swap with whatever nerd or nerds Gil decides to keep. The kind of media literate nerd Gil is looking for is someone from the mid 2010s who knows about classic D&D, has read Worm, and played obscure cult Classic PS1 RPGs. For someone that nerdy, knowing about Snow White and Warcraft are freebies, but being physically fit, socially apt, or useful in any other way is not.
Swap one of the T2 Shinra soldiers with the full intention of selling them off to get the sale price of a T4 mad scientist
Swap one of the T2 Shinra soldiers from Vanessa, assuming any of them don’t suck.
Swap a T1, any T1, and trade them for 10 credits to the Ziggurat. Gil comes out 9 credits ahead and some random other person can have a gender confused mad scientist super soldier. At least she’s pretty.
