for two per turn? Arc Blade is pretty bad, but that's a bit of a jump.
One damage per turn is interesting, but I like it a lot better when it's going to the dome every time. Using this as an awkward Drop of Honey effect seems out of flavor for the water torture idea and makes it, as asi correctly points out, a bit too similar to Honden of Infinite Rage. If you dropped the cost a bit and changed it to hit players only, I'd be happy with it.
