Blood Channels are blocks that act similarly to a fluid and can function as a replacement for noisy, lag-inducing flowing water in many constructions. They are very similar to Slime Channels in their function as blocks, but they cannot be made into a Bounce Pad .
Blood Channels will flow away from you when placed. If you hold shift while placing the Blood Channel, it will instead flow towards you. Blood Channels are not solid blocks; they act like a fluid in that they will allow you to sink through them and swim up through them. They always have a direction of flow, and will push mobs and items through them as any flowing liquid does. It is possible, if somewhat difficult, to drown in a Blood Channel block. Unlike a liquid, Blood Channels have a selection box and allow other blocks to be placed against them, rather than being replaced by any placed block. They do not spread outwards, like a normal liquid (such as water or lava).
Blood Channels can only be made using 1 Redstone and 4 Coagulated Blood. This is a shapeless recipe.
