The Tavern

?Teleport makes Monastery of Wucad Mu trivial. You enter, you are on the clock against summoned monsters so you pop 1 or 2 ?tele scrolls. You don't even have to fight the statue unless you want the Wucad Mu staff - ?acq, !Xp, spellcasting manual are worth it to just ignore the statue.

Maybe we can forbid teleport like in Gauntlet?

I don't think it matters. You can generally just walk away from the spawned monsters if you're not a naga or barachi, and they'll time out. Statue is same as things like moon troll or even hell lords...if you don't want what they're holding you can jack the loot and leave.
