Reborn Fusion is a Miner's Haven tier introduced in The Ultimate Update. The tier is designed for items that are a mix between two reborn items influencing the item's design and effects. These items would be favored over the two reborn items it's made up off as they usually have better effects than the two reborn items by themselves. However, the reborn items that were included in the fusion are not compatible with it.
In the MHCI Submission Vault, when asked if there will be any more fusions, berezaa responded saying he does not wish to add any more. You need at least 1 Sacrifice to have the power to be able to unlock Reborn Fusions.
