Need tips to find ultra Pride

[MrLeitexxx]

This is one of the last achievements I need and am having trouble finding ultra Pride, any tips to easily find him in wrath of the lamb?

There is no tips to finding him. Clear every floor, that's it.

Just happened to see him for the first time yesterday.

AFAIK he's just a "rare spawn" in a sin room. If there's any particular way to cause him to spawn, I don't know about it. Best I can offer is check out every sin room that you can, but I'm assuming you've already been doing that...

Compass/The World/The Sun/Liberty Cap (sometimes) will show you if there's a sin on the floor. Other than that it's just luck.

remember, sins usually appear in dead ends

Play the Doctor's Revenge challenge and bomb yourself through the rooms until you find him.
