As far as I know you can only polymorph to stop burning,but you will continue to burn once you return to your original form. Although, polymorphing will give you precious time to find some healing.
Did you know that whips can be made out of quicksilver?.. I sure didn't.
EDIT: Turns out that it is not very practical because wielding it requires 184 strength.

I killed everyone in New Attnam, but I can't find the Left Nut. I used a lot of explosives, so can it be destroyed?
Or I should just wait until every corpse will rot and then use a scroll of detect material?
When you use the wand of resurrection on a dead fish it says "The dead fish comes back to life, but quickly suffocates again" even if it is placed on a water tile.
It would have been nice if after one placed a dead fish on water one could resurrect it.
I know that this is a VERY minor thing, but I just had a spontaneous urge to write this topic for some reason...
