Dearest Monkalonk, I am thinking Iāma make a Monk for a 5e one-ish-shot, either Mark of Passage Human or Eladrin (for ājellyportationā). Does the Four Elements subclass count as having Spellcasting for the purposes of the extra Mark of Passage spells (and, if not, is there a Monk subclass that does have that)?
From context, I assume that mark of passage is a subrace or racial trait, and that it resembles a racial teleport power that double-elves have. It says under Four Elements monk that Casting Elemental Spells is spellcasting and you should look under the chapter on spellcasting, and all the abilities are things like hold person which is a spell, so, if I had to guess, Iād say it probably counts unless my understanding of whatever the hell jellyportation is is dead wrong.
My answer is āprobably but why are you asking me about 5e?ā
