The arcane spa is a block that will pump any liquid within onto the block that it is facing, either on itself or adjacent. To stop it pumping, you can apply a redstone signal. The gui allows you to choose whether to just pump the liquid put into it immediately or mix it first. The only mixing combination available so far is bath salts and water. This produces Purifying Liquid, which protects a character from Warp effects. To fill the Spa, right click on it with a water bucket in hand.
Arcane Crafting Table:
Place a warded jar in the middle of the grid. Place quartz blocks in the top two corners. Place iron bars above the jar and a piston below. Place arcane stone to the sides of the jar and piston.
