I'm not sure if this is the correct place for it however, the Flame Skull NPC in Wave Echo Cave in roll20 is a 5th level spellcaster, however, in the paper version he is a modified 5th level spellcaster, with one less spell slot of each level. So instead of 2 3rd level spell slots, he is meant to only have 1 and the same applies for 2nd and 1st level spell slots.
