Today I'm going to have to go with the witches cauldron from Witchery, a mod that (unfortunately) didn't make the jump. With the witches cauldron you can make custom potions, wit many different effects
Good choice!Today's block is Leaf-eating Generator from ActuallyAdditions:
It generates power by destroying leaves, thus is useful in combination with tree farms. Also helps to get rid of big trees remains.
It keeps its energy when broken, so I use it as a backup portable battery for the energy systems, especially when Refined Storage network runs out of power.
