ToME: the Tales of Maj'Eyal

For some reasons my teleport runes always fail during the ambush, but other sources of teleport work. Is this intended?

It's the size of the map... Because its so small, a radius 30 TP will very likely fail, not to mention radius 60 or that much.

Perhaps teleports that can't find any places in the valid radius should try again with no minimum instead of giving up? This would make them work in the arena, too -- it's kind of a pity to have some abilities just become useless like that.

They do work in the corner, and is useful because the only place it will teleport you is the opposite corner. Not sure if all work, but the ones with lower minimums do.
