ToME: the Tales of Maj'Eyal

What if you were allowed to teleport to areas of a vault that you could see? It sucks being a temporal whatever and not being able to zip around all willy nilly. For now I just kite out as much stuff as possible, but on some vaults that's really un fun.

Not to mention trying to battle farportal guardian in the fortress (which is all no-teleport) and having no gap-closers when it bombards you with frost nukes. I don't know what I'd do there without Wanderer's Rest, as it was a bloated horror and had no real way to be kited.

I think it might make sense if you can teleport when in a vault - but only to other vault squares.
Of course, that might make vaults MUCH harder since you're no longer guaranteed being able to escape....

I had a High Peak vault glitch last playthrough and close a 'secret' door behind me.

I would've been very sadface if teleport didn't work. While that's a bug being worked around, vaults are often complicated areas that block digging, unlike normal spaces. Providing a 'get the heck out' is really nice to have.
