Any chance someone would be willing to help me farm White Character Tendency? (PS5)

I've been trying to earn the Ally's Ring and am starting to learn that doing so in NG+2 was a bad idea. I wasted the black phantom in World 3 by using poison (apparently, it doesn't count towards character tendency if they die via poison) and the World 4 phantom is kicking my teeth in.

Any chance someone would be willing to invade me a few times? I'll help in turn if I can.
