You were doing well up to Palkeera.

Tsutsaroth - Elder Demons

Alyaroth - Greater and Black demons

Byzroth - Lesser demons

Kal'Gerion - Infernals(This only includes the generals, all other demons following Kal'Ger are Avernics)

Mahjarrat don't regurgitate it because it makes them sick. Why would you keep something inside yourself that serves no purpose?
