Topic is simple, after completing diaries in OSRS you can obtain 1 free death revive at zulrah, where when you die your character instantly comes back to life.
I know this was suggested for HCIM but instead of just giving it to HCIM I think a better idea would be to either lock it behind a certain donor rank or even add another money sink into the game. Add a NPC that would offer the ability to save you from Zulrah for a certain amount of ingame currency. I personally enjoy the 2nd option since it can be another money sink into the game and it wouldn't lock the option from HCIM who simply can't afford the donor rank, instead they can grind ingame for the gold needed until they do something where they can risk their HCIM status.
