Covenant ranks 1–10 and how to beat Covenant 10

Covenant 10 is the top difficulty. Every rank keeps the rules of the ranks below it, and you unlock the next rank by beating Seraph Aeternus at the current one. Runs that win at Covenant 10 usually build one unit or one floor that scales every battle until it can kill Seraph by itself, keep the deck small, and take boss artifacts that feed that plan.

What each rank adds

Rank	Rule added	What to do about it
1	Enemies are stronger; your starting deck gets extra random cards: a pair of commons from each clan and an uncommon banner unit	The only rank with a benefit. Learn new clans here.
2	Battles have extra enemies	Area damage and Sweep units gain value.
3	Merchant rerolls cost 50% more and purge costs rise 50% faster	Purge early, before the price climbs; reroll less.
4	Bosses gain Attack and Health; non-flying bosses gain an extra mechanic	Check each boss’s Covenant 4 ability on its boss page.
5	Two Vengeful Shard Blights in the starting deck	Unpurgeable; each deals 1 to your Pyre if left in hand (Reserve) or costs 1 Ember to play away.
6	One card per draft also adds a Calcified Ember	One offered card in each draft carries it; taking that card adds the Blight. It costs 3 Ember to play and then Purges itself.
7	No empty wave before bosses	Your units fight the boss straight after the last wave; set up healing and buffs a turn earlier.
8	Enemies are stronger	The second stat jump; boss stats rise again at Covenant 8.
9	Your Pyre starts the run with 30% damage	High-Health Pyre Hearts and Holystone heals matter more.
10	Elite Chosen enemies appear in flying-boss battles	Chosen units replace some ordinary enemies in those waves, Seraph’s fight included.

Covenant 1–9 and Covenant 10 keep separate win streaks. Beating the Titans on Covenant 10 rolls the credits.

The plan that wins

The winning runs described in Steam guides and threads share three habits:

1. One scaling threat. A unit that gains Attack permanently every turn or every kill (Harvest, Rally, Punish, Revenge, Slay effects) and gets Multistrike from a Frenzystone. From Covenant 2, Ring 8 waves hold five or six enemies, so a +5-per-death unit grows fast.
2. Space for it. Heaven’s Light adds 2 Capacity to every floor; a Smidgestone sets one unit’s Capacity to 1. Either lets you stack three or four copies of the threat on one floor.
3. A thin deck. Purge starter cards you no longer play so the engine pieces come up every turn. Covenant 5 and 6 add Blights you cannot remove, which makes every purge more valuable.

Example: Wickless Barons (any clan with Melting Remnant)

Joey Ortiz cleared Covenant 10 with every clan using this plan:

• Wickless Baron (1 Ember, 5/15): Harvest +5 Attack and +5 Health, triggered by any unit dying on its floor, yours or the enemy’s.
• Put three or four Barons on one floor with Heaven’s Light or Smidgestone, and give each a Frenzystone.
• Feed the floor with deaths: Remnant Host (0/1, summons 2 Draff when it dies), Votivary (1/1, Endless, draws 2 next turn when it dies), Dreg (0 Ember) and Entombed Explosive (65 damage to the front enemy on death).
• With Underlegion as the ally, Eager Conscript and Cluster Colonel spawn Funguy whose deaths also feed the Barons.

He reports Barons at 400–600 Attack by the final boss. The guide predates later patches; the card text above is checked against the 10 November 2026 patch.

Example: Banished at Covenant 10

Replies in the Steam thread on Banished at Covenant 10 name Fel on the Unchained path (permanent Valor on every Shift) with Punk Shredder for Trample and Imprisoned Zephyr plus Windblade to trigger Shift every turn. Shield of Wyngh (Revenge damage equal to the unit’s Health) and Avenger were named as the two Banished cards most worth taking.

More plans for every clan, including the Punished, are on clan combos that win.

Boss artifact choice

After each flying boss you pick one of three artifacts:

Artifact	Effect	When it fits
Hell’s Flame	+1 Ember per turn and +1 Deployment Ember	Expensive cards, or when you need more units placed before the fight.
Limbo’s Solace	+1 card drawn per turn	Decks that need specific pieces each turn.
Heaven’s Light	+2 Capacity on each floor	Stacking copies of one threat on one floor.

Each also raises your Pyre’s Attack and Health by an amount that depends on the Pyre Heart. PesNRen’s guide reports taking Heaven’s Light or Hell’s Flame first in almost every run.
