Part lava

Part lava is a level 2 custom brew effect component from Witchery. The Part lava effect can be obtained by putting a Cobblestone block in the brew before bottling.

An instant splash potion with the Part lava effect will cause all of the lava blocks (flowing and still) within the brew's range to vanish for the amount of time defined by the brew's duration component. The blocks that were lava blocks will appear much darker.
