Blighted overload (2)

High alchemy turns Blighted overload (2) into 30 gp. Buying one at 5,211 gp (its guide price, as it has not traded today) and casting with a nature rune at 138 gp costs 5,349 gp. That is a loss of 5,319 gp per cast at its guide price, so it is not worth alching for profit right now.
