Raging echoes hat (t3)

High alchemy turns Raging echoes hat (t3) into 60,000 gp. Buying one at 2,218,747 gp (its guide price, as it has not traded today) and casting with a nature rune at 138 gp costs 2,218,885 gp. That is a loss of 2,158,885 gp per cast at its guide price, so it is not worth alching for profit right now.
