Blood Moon

The Blood Moon is an event that occurs in Zeth'Gol in Tanaan Jungle, the purpose of it to empower using a massive amount of blood magic.

It cannot be attacked by normal means, so in order to defeat the Blood Moon you will need to gather the Drained Blood Crystals that are scattered around Zeth'Gol. Upon being fully drained, the Blood Moon will spawn Remnant of the Blood Moon.
