The best starting deck for Ashes of Morgravia is the Bloodsworn Onslaught, a Crimson Covenant build that leverages self-damage for overwhelming offensive power. It's simple to pilot, remarkably resilient, and specifically designed to conquer the game's first two major bosses right out of the Weeping Catacombs. Forget the slow, meticulous setups of the Grave-Whisperers or Argent Order; this deck wins by turning your own lifeblood into a weapon, establishing a tempo that early-game enemies simply cannot handle.
This guide breaks down the entire strategy, from the core cards and upgrade paths to the specific tactics required to dismantle the Carrion Knight and the Matron of Webs. With this build, you'll stop struggling and start dominating your runs.
Why the Bloodsworn Onslaught Dominates the Early Game
Most new players in Ashes of Morgravia fall into the same trap: they play too defensively. They try to build a perfect wall of Block against every incoming attack, only to be worn down by curses, multi-hit attacks, or overwhelming numbers. The Bloodsworn Onslaught flips the script. Its core philosophy is that your Health is just another resource to be spent aggressively.
This build excels for three key reasons:
- Unmatched Speed: By using cards like Blood Tithe to trade health for card draw, you cycle through your deck faster than any other starting archetype. You find your key damage cards more consistently, ending fights before enemy mechanics spiral out of control.
- Explosive Scaling: The deck's power isn't linear. Cards like Sanguine Strike double in effectiveness when your health is low, while skills like Vessel of Agony turn the damage you take into a permanent Strength buff for the combat. Enemies are forced into a no-win scenario: either they don't attack you and let you set up, or they attack you and make you stronger.
- Simplicity of Execution: The core loop is straightforward: take damage, draw cards, gain resources, and unleash a devastating attack. There are no complex, multi-turn combos to memorize. This makes it perfect for learning the game's fundamental mechanics while still feeling incredibly powerful.
The Core Card Package
This build revolves around a tight-knit group of ten cards from the Crimson Covenant faction, available right from the start with the hero Lyra, the Bloodsworn. Your goal during the first act is to remove weaker starting cards (like basic Strikes and Defends) and secure copies of these key pieces. The synergy between Blood Tithe and Sanguine Strike is the engine that drives your victory.
Here is the essential list of cards you need to assemble:
| Card Name | Type | Cost | Effect | Role in Deck |
|---|---|---|---|---|
| Sanguine Strike | Attack | 1 | Deal 6 damage. If your HP is below 50%, deal 12 instead. | Your primary single-target finisher. |
| Blood Tithe | Skill | 0 | Take 2 damage. Draw 2 cards. | The core engine. Turns health into card advantage. |
| Crimson Pact | Power | 1 | At the start of your turn, take 1 damage and gain 1 Mana. | Solves energy problems and enables bigger turns. |
| Grave-Iron Blade | Attack | 1 | Deal 7 damage. Gain Soul-Shards equal to unblocked damage. | Your main generator for the Soul-Shard meter. |
| Exsanguinate | Skill | 2 | Spend all Soul-Shards. Deal 3 damage to ALL enemies per Shard. | The ultimate board clear for multi-enemy fights. |
| Vessel of Agony | Skill | 2 | Gain 10 Block. If you took unblocked attack damage this turn, gain 2 Strength. | Defensive tool that scales your future offense. |
| Reckless Lunge | Attack | 0 | Deal 4 damage. Take 1 damage. | A free attack that enables self-damage synergies. |
| Hemomancer's Gift | Skill | 1 | Heal 5 HP. If you have taken damage this turn, draw 1 card. | Your only source of sustain and a potential card draw. |

How to Pilot the Deck: A Strategic Breakdown
Mastering the Bloodsworn Onslaught is about managing your health as a resource, not as a score. You want to hover between 40-60% HP for most of a fight, where cards like Sanguine Strike are active but you aren't in immediate danger of being defeated.
Your Ideal Opening Hand
In your opening hand, you are desperately looking for one card: Crimson Pact. Getting this Power into play on turn one is the single most important move you can make. It provides an extra point of Mana every turn for the rest of the fight, allowing you to play more cards and establish control. If you don't have it, look for Blood Tithe to dig for it. An ideal opener is Crimson Pact, Blood Tithe, and a solid attack or block card.
Building Your Engine
Your mid-fight goal is to establish a rhythm of controlled self-damage. Use Lyra's innate ability (Pay 2 Health: Gain 1 Soul-Shard) and cards like Blood Tithe and Reckless Lunge on your own terms. This thins your deck, loads your hand with options, and fuels your Soul-Shard meter for a massive Exsanguinate. Don't be afraid to take a calculated hit from an enemy if it means you can play Vessel of Agony to gain Strength. Remember, damage taken on your terms is often a net positive.
The Finishing Blow
The deck has two primary win conditions. Against single, high-health targets like elites or bosses, you'll whittle them down with Grave-Iron Blade and other attacks. Once your own health dips below 50%, an upgraded Sanguine Strike+ becomes a low-cost nuke that can end the fight. Against groups of enemies, the strategy shifts. Spend the early turns using your abilities and attacks to build up at least 5-6 Soul-Shards. Then, unleash Exsanguinate to wipe the board, leaving any tougher enemies exposed for a follow-up attack.
Navigating the First Two Acts
The Bloodsworn Onslaught isn't just powerful in a vacuum; it's practically tailor-made to counter the first two major hurdles of a run.
Defeating the Carrion Knight
The boss of the Weeping Catacombs, the Carrion Knight, is a roadblock for many new players. His high armor and ability to summon two Decrepit Ghouls can overwhelm slower decks. Our strategy bypasses this entirely.
- Ignore the Ghouls (at first): Do not waste your single-target attacks on the summoned ghouls. Focus all initial damage on the Carrion Knight himself. Use this time to play Crimson Pact and draw cards.
- Build Soul-Shards: Use Lyra's ability and any Grave-Iron Blade hits on the Knight to accumulate Soul-Shards. Let the ghouls hit you if you have a Vessel of Agony in hand to gain Strength.
- Wipe the Board: Once you have 5+ Soul-Shards, play Exsanguinate. This will instantly kill both ghouls and deal significant damage to the now-exposed Carrion Knight.
- Execute: With the ghouls gone, the fight is a simple damage race. Use your empowered Sanguine Strikes to finish him off. The Knight has no way to deal with this sudden burst of area-of-effect damage.

Overcoming the Matron of Webs
Deep in the Silk-Veiled Grotto, the Matron of Webs presents a different challenge: she applies stacks of crippling Poison and Web debuffs, which reduce your damage and prevent you from playing more than two cards per turn. The Bloodsworn Onslaught's sheer speed is the perfect counter. The goal is to defeat her before the debuffs can stack to critical levels. The constant card draw from Blood Tithe helps you find your key damage cards quickly, while the front-loaded power of a low-health Sanguine Strike can often end the fight in 3-4 turns, long before the Poison becomes lethal.
Upgrade and Card Choice Priorities
Your choices at campfires and after combat are critical. A focused upgrade path will elevate this deck from strong to unstoppable in the early game.
Your top priority at any Forge is to upgrade Sanguine Strike. The upgraded version, Sanguine Strike+, deals 8 base damage and a massive 16 when you're below 50% health. This is a huge power spike. Your second upgrade should be Vessel of Agony+, which increases the Block to 14 and the Strength gain to 3, making it one of the most efficient defensive cards in the game.
When adding cards to your deck, be disciplined. You're looking for more copies of your core cards, especially Blood Tithe. Beyond that, look for premium Crimson Covenant cards that fit the theme. Taste of Blood (1-cost Attack, Deal 5 damage, Heal for damage dealt if the enemy dies) is an excellent addition for sustain. Avoid diluting your deck with cards from other factions or low-impact generic cards. The goal is consistency.

Frequently Asked Questions
Is this deck still good in the late game?
Yes, but it requires adaptation. The core engine of self-damage and card draw remains powerful, but you'll need to add some late-game scaling cards. Look for Blood Boil, a Power card that doubles the damage you deal for one turn, or Final Sanction, a high-cost attack that deals more damage the lower your health is. These additions allow the deck to handle the massive health pools of Act 3 and 4 bosses.
What if I don't get offered Crimson Pact early on?
If Crimson Pact eludes you, the deck is still viable, but you'll need to manage your Mana more carefully. Prioritize removing high-cost cards and look for relics that provide energy, like the Cursed Monocle or the Ever-Beating Heart. You will play more defensively until your deck is thin enough to cycle back to your key attacks consistently.
Can I run this build with other heroes?
While Lyra is optimal due to her Soul-Shard generation, the core card package works well with Marek the Scourged. His starting ability, "Once per combat, pay 5 HP to apply 2 Vulnerable to an enemy," provides a different kind of offensive burst. It makes your key attacks hit even harder, offering a more aggressive, all-in variant of the strategy.
Your First Victory Awaits
The Bloodsworn Onslaught is more than just a collection of strong cards; it's a lesson in one of Ashes of Morgravia's most important concepts: calculated risk. By embracing the Crimson Covenant's dangerous philosophy, you gain access to a level of power and speed that makes the early game trivial. It provides a clear path to your first victory and teaches you the aggressive mindset needed to conquer the game's darkest depths. Build this deck, trust the strategy, and watch the horrors of Morgravia crumble before you.
