Boss order and gear checks

Bosses in the order their level implies, each with the gear the game has actually made available by that point. It is built for one question: are we under-geared, or are we fighting it wrong?

How to use this honestly

Item level is a real number in the game files, and so is each boss's level. Comparing them tells you whether the game expects you to have better gear than you are carrying. It does not tell you the fight's mechanics — the files contain stats, not tactics, and we are not going to invent a strategy guide and dress it up as data.

So: gear far below the boss's level is a gearing problem you can fix from the tables below. Gear at or above it means the answer is mechanical, and no wiki number will save you.
