Specifically, this test server update introduces the new Sorcery and Summoning skills, which lets players craft a character that can use summoned Wisps to summon even bigger temporary critters like chasers and constructs, or even use those wisps to create magical armor or consume an orb to provide increased regeneration for a short time. Would-be Sorcerers will need to bear in mind, however, that wielding a Sorcery weapon restricts them from receiving healing from outside sources.
