Managed to do the Shard of Fear part solo.
Feign Death and Divine Aura will get you the first 4 no prob. For the 5th one, I did the two ring events solo. I have mostly legendary and a few fabled items. Harm touch/Divine Aura and my unglued alchemist necklace helped out a bunch
After you get the 2 hearts to get into the ring of fire area, just run up to the top pyramid and grab the last chest, use feign death and/or divine aura to nab it easily.
