ToME: the Tales of Maj'Eyal

So recently I was playing ToME with the Yeek Archmage Let's Play and had a problem with the Tunneler getting stuck at the very end of the first instance of the Alternate Sandworm Tunnels.

ToME - Yeek Archmage Ep 9 - Alternate Sandworm Tunnel

Just after 28 Minutes in the video you'll see him just sitting there next to the level change with an enemy on top of the exit blocking him from entering the square.

Had I been playing any other type of character I may not have bothered to try to clear the Sandworm instance.

Exact same thing just happened to me.

This character had the Tooth of the Mouth, so he could juuuuuust barely tunnel through the sand fast enough to not die (though he DID die when I accidentally cancelled digging early once... he didn't get credit for his previous efforts, and he was unable to dig while suffocating, so he lost one life to that.

Finally dug his way to the exit, and there's the big worm, waiting politely for the little enemy worm to get off the pot.
