Blood crucible info

Blood crucible + delirium:
You can gain delirium rewards from crucible monsters at a reduced rate (similar to other league mechanics such as breach)
You cannot gain item corruption from delirium monsters (Items in blood crucible only gains corruption from crucible monsters)

Corruption rate gain:
Crucible monsters must be above a certain level for your item to absorb any corruption. You can see this level when you hover over the item in the crucible: "Level ##+ corruption absorbed".
Amount of corruption an item absorbs only depends on the number of monsters killed (not monster level).

Multiple Crucible slots:
Every item in the crucible will get the same amount of corruption which is not decreased by having more items in the crucible.

Tiers:
To corrupt an item to tiers 1, 2, & 3 the item level needs to be at least 1, 45, & 68 respectively.

If there's any other mechanics you know about (Like corruption buff) please let me know, thanks.
