Its a built in part of the class, and you think we should add a layer to for the sake of forcing someone to RP more if I am gathering it right?

Its one of the only things in the game that even when you do it 100% correctly you can still lose hundreds of hours of investment.

There are other classes that get a comparable power level with substantially less investment of time and effort and also without a risk of losing their character.

There is already a quest involved with becoming a mummy, gating a quest behind another quest is just unnecessary. Honestly, if we did anything to change the mummy quest then we would probably have to consider removing the failure chance from it.
