Valiant custom monsters[edit]

When you created MAP32: Ghosts of the Old Kingdom (Valiant) you mentioned it "is the only level in Valiant where invisible revenants and arch-viles appear". But those are not described in the custom monsters list. Do you have more info on them? I'm trying to complete a mapping table in order to automatically generate correct Things tables for all Valiant levels. Given your familiarity with this megawad, your help with that would be welcome. --Xymph (talk) 02:57, 31 December 2016 (CST)
