Well the first time it died, it died by a random undead I mind controlled with the undead sumtin sumtin spell. The crystal undead killed it and it never dropped the pendant. I tried ever since that time to kill it, restarting the game and console, resting at the bonfire and even used the ring that made u get more items but nothing happened.
My character is at the final stage before killing that king guy, the last time i played it, and completed literally everything there is in the game, and i even saved that oolicile girl at the lake with the Hydra.
Do i need to play a whole new character for it to work or something? It sucks if that's the case Can anyone help ploxxxxx
