I'm curious if there is a ruling on this topic. Specifically the debate was over whether a Loxodon Way of the Shadow Monk could benefit from the massive stealth advantages and ninja-teleportation. This would apply equally I presume for Centaurs and other larger (but still medium) playable races.
Speaking of "flavor" it seems a Loxodon/Centaur ninja would be highly ineffective. A 7ft tall 400lb elephant probably wouldn't make a great ninja, right? It makes sense from a world concept level.
But is there actually anything in the rules that would give these large (but still Medium-sized) creatures disadvantage on Stealth checks?
