[Haunted Evil Pajamas]

Boxer's passive Fighting Pace recovers FP when you end your turn with at least 3 momentum

Dullahan Soul Generator recovers FP equal to your remaining momentum*2 when you end your turn.

Both work by themselves, but when you equip Soul Generator while being a Boxer with Fighting Pace, it does not stack, only Soul generator takes effect.
