Covenants are the difficulty dial
Covenant levels are how Monster Train measures a harder run. Each level layers on a new rule. Some remove a convenience. Some strengthen enemies. The stack grows as you climb.
The reward for climbing is the challenge itself and the mastery it proves. The cost is that every mistake is punished harder, so preparation matters more at each step.
What changes as you climb
Higher covenants tend to remove safety nets and add pressure. A level might limit your draft options or give enemies a head start. The exact list depends on the level, so we mark it instead of stating numbers we have not verified.
The point is steady: each step asks for a more complete deck. A deck that squeaked by at one level will fail at the next without real improvement.
Prepare before you step up
Before raising your covenant, make sure your current level feels routine. You should know which clans you draft, which relics you skip, and how you answer each boss type. Uncertainty at a low level becomes failure at a high one.
Build the habits first. Then the covenant climb is a test of habits you already have, not a gamble.
Play to your strengths
At higher covenants, generic decks fade. You need a plan that survives the extra pressure. Lean on the clan pairing you know best and the floor setups you trust.
The boss strategy page helps you answer the fights that covenants make stricter. Read it before you climb.
Climb on your terms
Do not raise the covenant because a number looks impressive. Raise it because the current run is comfortable and you want the next test. Comfort first, then challenge.
