Create a room with an Aumtlich (or similar beam-emitting monster).

Give the player some sort of weak sword.

Have the player take on some enemy with a high amount of defense but that can't hurt the player (say, a Wubba).

Attacking this enemy turns off the Aumtlich beam for the turn. Attempting to initiate combat again keeps the beams off, until the player takes another turn where this sort of situation doesn't occur. This can be exploited. If the player steps in the beam and attacks the Wubba on exactly the same turn, the beam will get turned off before it harms the player, and the beam can be crossed if the player moves before the beams come on in the next turn.

I'll work on fixing this bug.

Fixed in rev 107 so that, on conclusion of combat (e.g., following multiple consecutive no-damage hits), room events like the aumtlich gaze always get processed.

Confirmed fixed for 1.2.3.116. I tested other aumtlich attacking you from behind, and an aumtlich that moves backwards and ends the fight after its attack, and the expected beam damage followed after the fight resolved.

An interesting observation: if you die fighting an aumtlich, his beam will hit you one final time for 1 damage while your death animation is playing. It is of no meaningful consequence, because you're dead, but it's a thing that happens.
