Stats on Gamma's battle protocol: Shiva, as briefly seen here: https://www.deviantart.com/crydius/art/Gamma-s-magic-page-5-739016769
Same thing as I did for Eldritch's Mark of Nurgle, over here: https://www.deviantart.com/crydius/art/Eldritch-Mark-of-Nurgle-761257318
As you've probably noticed by now, Eldritch's batlle forms, or "Marks", are based on Chaos Gods from the Warhammer series, while Gamma's battle protocols are based on Summons from the Final Fantasy series. (Hence the one winged angel thing she's got going on.)
