The Displacement Rune increases the flow rate of Life Essence into and out of the altar when pumping to and from an external Tank multiplicatively by +20%
With some Netherite Scrap and some Intricate Hellforged Parts looted from the Demon Realm, you can double the power of your Displacement Rune, increasing the flow rate by a multiplicative +40% per rune.
If you change your mind, you can undo the recipe in the ARC.
