Crafting

Deterministic craft reference: pick a base and an item level to see exactly which prefix and suffix tiers can roll. Straight from the game's mod data.

The game data does not carry modifier weights, so this page does not print chances. It lists what can roll and from which item level, with tiers counted the game's way: T1 is the best.

Desecration

Desecrated modifiers, grouped by the Abyssal lich whose mark they carry. Abyssal bones offer picks from these pools.

Which of these can actually appear depends on the base's defence types.
