Prof. Toast's Arcane Orb

Prof. Toast's Arcane Orb is a hastily made mystic orb given to Astrid in The Vault of the Sages in Silverymoon by Prof. Toast.

"It occurs to you that someone working for this library probably shouldn't know blood magic so well."

This Arcane Orb has been configured Prof. Toast to have three charges that can be activated to minimise the effects of a failed curse save.
