Panacea Quest

div potion to get to the ticket for this item, go to the lower part of greed's gallows, and wander around to roughly the middle of the south side of it, until you find a door to the south

I don't think it has a key, but pass door will let you through. The room is no-quit, so you can't be greedy.

pick up the white journal off the floor, and teleport to zikthro and give him the ticket now you have a div potion

From portal point Pod Of Manatees:

• Go to the lower part of greed's gallows, and wander around south until you find a door without a key. Use Pass Door to go one south.

• Get the White Hardback Journal form the ground.

• This is a cursed, no-quit room. You must portal out to Zikthro.

• Give the journal Zikthro and receive panacea.
