Chits are a family of in-game prizes first announced on October 24th, 2012 for an upcoming Halloween event. An August 13th, 2013 announcement introduced the copper chit, while the iron chit was announced on August 24th, 2013. The tin chit can be turned into any 103+ Immortal, while the rest require a 104 to activate. All chits barring the copper and iron chits have a set turn-in window, after which time they expire.
