Contaminated Soul Crook

We've been hearing Poluto's howls again. Why didn't I think that there would be more than one Poluto? It may be too late for me, but at least I can help save some of the other people trapped down here.

You fought Poluto once, so it wouldn't be difficult to fight it again, would it? Please get rid of the new Poluto.

This one is likely to be wary of anyone entering its lair after what happened to its predecessor. I'll give you some bait you can use to lure it out into the open.
