Limit Break Dancing
Absolutely none. They are mechanically identical, just like several other weapons in the game (sickle and club, glaive and halberd, etc.)Okay, so what's the advantage of having a weaker trident? What does a trident do that a spear doesn't?
What I'm trying to say is, "not getting an advantage" isn't the same thing as "being penalized." A character isn't being punished by choosing a trident (or any other weapon) for thematic reasons.
