[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

[Dragonstrike]

I personally think the reasoning for it stopping to work after the pokemon leaves the field is because the user isn't there to maintain the power. Wrap, Bind, Clamp etc. and Mean Look/Block work like that for obvious reasons, so it's not too far fetched to say the same happens for the ranged semi-trapping moves.
