SPOILER. abrahamwl_protected_by_tso_1

[Sandman25]

I met a daeva in an isolated Depths 3 vault and I cowardly retreated being a Mu of Chei without wand of teleportation.

After the game I found it was "abrahamwl_protected_by_tso_1" but I am not an expert in reading des files.
What's in the vault?

[chequers]

A (TSO-friendly?) item as if from a scroll of acquirement.

[gammafunk]

That's not right. It generates two high quality items, and these are not as if from acquirement (which would mean based on the player), just high quality. It's guarded by two monsters, each of which have equal chance to be a daeva or an angel, and each with a 10/11 chance that it will be generated awake. There's also a TSO thematic message that gets printed at one point when you walk in the vault, but it has no other effect.
