It's this character, but IDK where you'd find her other than maybe looking back on the alien ship? Cant be fucked to scour all that.
Also, to cheese the game, you get the phantom as you progress in the story (I don't even think you have to go back and get anything like the other bonus spells), it's gamebreaking for the challenge rooms, just fill the main player with that spell (there's a ring that boosts its attack as well) and give the NPC twin a grenade launcher to use as tanky enemy bait, and you can get all the purple guns you want for the castle section (castle section's sprawl makes the phantoms a kinda bad choice tho). You could beat it on hard with the phantoms for most of the game.
