Why Won't You Die? is an achievement that requires the player to kill five rock crabs on the shore near Rellekka or on Waterbirth Island.
- This achievement used to be a task prior to the release of the Achievements System on 18 April 2017.
- The name of this achievement may be a reference to The Elder Scrolls IV: Oblivion. The line is commonly heard during combat in the game, as well as discussions on mudcrabs, which bear a resemblance to rock crabs.
- Alternatively, this may be a reference to the final fight scene from the movie V for Vendetta. This is asked of V by Mr. Creedy, as V has incredible stamina after taking dozens of gunshot wounds.
- This may allude to the relatively high life points rock crabs possess.
