Colossal Blood Chest
Blood Chests are great, throw in your damaged stuff, and they come out repaired. One downside of using that machine is the occasional bad effect your items can get, and it can be quite annoying to continuously clear that effect with your Purifier.
Actually, the disadvantes don't stop there. The Blood Chests has a very small inventory to put your items in, it is slow, has a small tank size and is really slow. Worst of all, my Promises can't even be used to boost the machine!
That is why I created the Colossal Blood Chest! It solves all of the problems I have mentioned As a logical consequence, this machine is quite a bit bigger than its regular variant. Because of this massive size, I had to make use the strange powers of Undead Planks to be able to hold the structure together.
This Colossal Blood Chest should only be used if you have a lot of items you need to repair at once. The reason for this is that its base Blood usage is higher than the usage of the Blood Chests, but the more items that are being repaired simultaneously, the more efficient this Blood usage becomes.
To build this, make a hollow 3x3x3 structure of Reinforced Undead Planks. For the structure to form, your need exactly one Colossal Blood Chest block somewhere in the structure wall, make sure not to place it in the middle of the structure, as it must remain hollow.
