EATER_TOMB and ENTOMB are redundant achievements

[John Snail]

The addition of 2 achievements for entering Brightsheol (one for specifically completing the Tomb of the Eaters quest) is strange, considering there are already 2 achievements for doing this; you can’t avoid them.
Unlike the other main quest achievements, these just feel like padding and are surprisingly uninspired for Qud achievements. Most players will not complete Tomb of the Eaters outside of the quest, and the completion dates of the other main quest achievements are good enough context.

One could instead be something like "Entomb yourself without the Mark of Death." This one's an interesting challenge since you have to deal with the hordes of conservators and cherubim. (Relevant: #10250)
Another could become a speedrun achievement, like "Entomb yourself in 20000 turns or less." The exact number of turns would be tuned throughout the rest of the beta, but this seems fairly reasonable with sources of quick level-ups like the Banana Grove and Rainbow Wood (could be an organic way of teaching players how to level up this way too!).

"Entomb yourself without the Mark of Death."

you need the mark to enter the sarcophagus, even if you kill herododicus to pop the seal

I’m aware, that suggestion is assuming the restriction would be lifted.
