Didn't think to check it. My greedy eyes locked on WHUPAZ.

edit: Ok found it again. @Darvin: That strategy doesn't work, in the mana burn phase every time you explore a new square you get mana burned again >.>
I touched the altar, said yes to some text and it gave me a potion which restores 10 health and 0 mana. I drank the potion and it cured my poison and mana burn but it didn't lift my weakining (5) and corrosion(8!). Doesn't really seem worth it, probably the best thing to do is beeline to the altar to get a mana burn/poison cure potion unless you have JJ to cure you.
Added the pics to the gallery, you can read the text yourself - https://imgur.com/a/1VV0A
