I believe you...
but feels inconsistent with the fact that it's a conjuration. I guess I was under the impression that conjurations stayed in a zone. Seems like it should have been a trap enchantment card.
curious to hear the reasoning about what the difference is.
I think it's consistent; walls, temples, tanglevine, etc, are all conjurations. I'm not sure what other category this would fit into. You're creating quicksand under a target. Seems like a conjuration to me.
I agree in theory... But walls, etc stay where they were conjured and don't disappear once "spent" (tangle vine being the other exception).
The way it's implemented feels more consistent with the hellfire trap or teleport trap behaves. (Single use on a single creature)
Anyway... I can get used to it. Just feels different than the other types of conjurations that stay in the zone.
