What exactly does eating a can of mushroom do? What are its guaranteed effects and what are its chance effects?
Also, if you pickaxe a giant mushroom corpse, does this create mushroom flesh with the same effect as a can? (Or does it have to be magic mushroom, or does neither work?)

Damn. I just used six wands of haste with 6 charges each (from mirroring) and still did not get permahaste

Not my most horrible for sure, but a recent bad one:

I attempted UT3 and retreated to UT2 after Genetrix nearly killed me. Then I spent a shitload of time polypiling and enchanting and hardening my gear, and finally returned to UT3. I had two chameleon whips, and so far neither one had polymorphed anything it hit. Back on UT3, I hit a kobold which promptly polymorphed into an iron golem. Pretty shitty, but also pretty easy to outrun, so I started retreating. Then suddenly a carnivorous plant popped out, blocking my way. The iron golem was still a few steps behind so I had time to kill the plant and continue on my way... or so I thought. The whips decided to activate again, and turned the plant into a phoenix feather golem. Stuck between two golems I decided to just drink my sulphuric acid rather than get beaten to a pulp

Slob, you mean Muffenz didn't leave you any teleport wands Just kidding Muffenz. I'm not sure if we had any in the first place. Anyways I thought you already beat Ivaner?

I don't think it does. It stays white, but it is permanent. At least in my experience with the blink dogs. I have to try out perma-haste & perma-invisibility though! Frees up another ring

Looking at your stats, seems ready to me.

No, it doesn't. They are awesome though. It's good that you're carrying a few, not just one. One of the worst things that can happen is for the mystic light frog to teleport your light source away.

INVISIBILITY
That's all you need to know
Ring would be best, or just continually zap yourself with wands. Cloak is not a good idea, since fire/elec resistance is more important.

Atomic you probably just accidentally killed one of them. I believe you have to kill Richel Decos, his guards, the shopkeeper, the banana grower encourager, and the tourists. Let the elder, sumo, priestess, slaves, palm girls, and ostriches live.

Cool,thanks chaos. I'll add that info to the wiki
