What is Vow of Iron?

Vow of Iron is Deepwoken’s hard mode gamemode that challenges players to survive in a more punishing version of the world. Unlike the standard Pathfinder mode, Vow of Iron features:

• No health regeneration outside of limited Etris Flask uses
• Mementos instead of custom character builds
• Boss requirements at Power 5, 10, and 15 to progress
• Modified world with combined maps and new mechanics
• Auto-parry removal requiring manual timing for defense

This mode takes place 38 years before Pathfinder events, offering a unique perspective on Deepwoken’s lore while providing the ultimate challenge for veteran players seeking a true test of skill.

Getting Started: Character Creation

Choosing Your Memento

In Vow of Iron, you don’t create a custom build. Instead, you choose from available Mementos – the memories of fallen characters. Each Memento comes with:

• Pre-determined stat distribution
• Specific weapon/equipment restrictions
• Unique flaws and boons
• Set progression path

Pro Tip: Look for Mementos with early boss access like Simeon Horror or Trial memories. These allow faster progression through early game challenges.

Essential Starting Tasks

1. Check your memories and tasks immediately after creation
2. Sell memory shards early for quick notes to purchase talents
3. Prioritize movement talents like Rush Hour and Enhanced Flow
4. Unlock required boundaries before attempting boss fights

Early Progression: Power 1 to Power 5

Fast Leveling Strategies

The most efficient way to reach Power 5 is through Primadon farming, provided your Memento allows early access. Here’s why Primadon is ideal:

• Manageable at low power with proper dodge timing
• Generous note rewards for rapid progression
• Consistent loot that can be sold for additional notes

Combat Strategy: Focus on patience over aggression. Time your dodges carefully and wait for openings rather than attacking continuously.

Power 5 Milestone

At Power 5, you unlock:

• Main mantras and core combat options
• Essential talents for your build
• Access to first boss requirement (Shogun Captain)

Build Recommendation: Many Vow of Iron players prefer basic attack-focused playstyles over mantra-reliant builds, as resistances and clean execution prove more reliable for boss encounters.

Etris Flask Locations: Complete Guide

Etris Flasks are your only source of healing in Vow of Iron, making their collection absolutely essential. Here are all the locations:

1. Miners Landing Flask

Location: Near the carriage area

Strategy: Before leaving, activate the hidden boundary nearby – this saves across wipes and helps future runs significantly.

2. Songseeker Flask

Location: Right-side island near the church area

Warning: Avoid caves in this region as hostile creatures can easily end your run. Drop down carefully to grab the flask near Songseeker Church.

3. Frozen Valley Flask

Location: Near Frost-related equipment spawns

Danger Zone: This area is extremely dangerous due to Snow Knights and Deep Owl spawns. If enemies appear, logging out is safer than pushing forward.

4. Viridian Sanctuary Ruins Flask

Location: Final flask location in the ruins

Challenge: Expect heavy parkour and potentially broken jump pads. You may need to switch servers if jump pads are bugged. After reaching the ruins, grab the fifth flask and activate the Temple of Myrr boundary.

5. Additional Flask Purchase Locations

You can buy extra flasks for 250 notes each at:

• The Sable Estate
• The Red Lotus Keep
• The Viridian Sanctuary Ruins
• The Indigo Citadel

Pro Tip: Always activate boundaries near flask locations – they persist across wipes and dramatically reduce travel time on subsequent runs.

Critical Boundaries You Must Unlock

Boundaries are the most important progression tool in Vow of Iron. These permanent unlock points allow fast travel and save countless hours of dangerous traversal. Here are the essential boundaries:

Must-Have Boundaries

1. Primadon boundary – Before the fight (essential for early farming)
2. Miners Landing carriage boundary – Near first flask
3. Songseeker Church boundary – Critical for mid-game progression
4. Frozen Valley boundary – Near fourth flask, dangerous but necessary
5. Temple of Myrr boundary – Before Shogun fight, refills flasks

Boundary Strategy: Always prioritize unlocking boundaries over immediate progression. Missing these means repeating long, dangerous routes every wipe, which can cost hours of gameplay time.

Boss Fight Strategies

Shogun Captain (Power 5 Boss)

The Shogun fight is a major skill check that tests your patience and timing. Here’s the winning strategy:

Key Tactics:

• Patience over greed – Never get greedy with attacks
• Jump and parry – Focus on defensive maneuvers over offensive
• Delay cancels – Bait predictable moves by delaying your action cancels
• Half HP healing – When Shogun reaches 50% HP, create distance and heal
• Special attack baiting – Learn to recognize and bait his special attack

Critical Warning: The Shogun can use his special attack multiple times. Stay alert and repeat the bait-and-punish pattern until victory.

Power 10 and 15 Bosses

As you progress, you’ll face increasingly challenging bosses at Power 10 and 15. The general strategy remains consistent:

1. Learn attack patterns before committing to aggression
2. Use boundaries strategically for quick retries
3. Keep flasks full before attempting boss fights
4. Master manual parrying since auto-parry is disabled

Advanced Progression: Power 10 to Rat King

Power Management

After Power 5, note costs increase significantly, and meaningful upgrades don’t appear until Power 10. Focus on:

• Job completion for steady note income
• Boss farming for large note payouts
• Primadon runs if your Memento allows access
• Chest collection (carry to NPCs for opening)

Reaching the Rat King

Once you reach sufficient power, head to Songseeker Mines and follow this progression:

1. Activate the food closet boundary – Essential for quick access
2. Proceed deeper into the mines toward the Rat King arena
3. Prepare for the fight with full flasks and proper talents

Rat King Fight Strategy

Despite his intimidating appearance, the Rat King rewards disciplined play:

Winning Approach:

• Watch movements carefully – All attacks are telegraphed
• Clean dodges – Never overcommit to attacks
• Patience is key – Vow of Iron punishes greed more than anything
• Stay disciplined – The fight becomes manageable with calm execution

Pro Tips and Advanced Strategies

Movement Optimization

• Master glider usage – Unlimited glider uses in Vow of Iron
• Utilize ziplines – Heavily dotted around the map for quick traversal
• Boundary hopping – Plan routes around unlocked boundaries
• Server switching – Don’t hesitate to switch servers for bugged mechanics

Combat Mastery

• Manual parry practice – Since auto-parry is removed, timing is everything
• Stamina management – More critical than in Pathfinder mode
• Talent synergy – Build talents that complement your Memento’s strengths
• Environmental awareness – Use terrain to your advantage in fights

Resource Management

• Note prioritization – Buy flasks before talents when starting
• Chest logistics – Plan efficient routes to carry multiple chests
• Boundary investment – Always unlock boundaries before spending on cosmetics
• Flask conservation – Use only when necessary, know refill locations

Common Mistakes to Avoid

Beginner Errors

1. Skipping boundaries – The most costly mistake in Vow of Iron
2. Over-aggressive combat – Leads to unnecessary deaths
3. Ignoring flask locations – Limits healing capacity significantly
4. Poor Memento choice – Some Mementos make progression much harder

Advanced Pitfalls

1. Neglecting manual parry practice – Essential for late-game success
2. Inefficient chest running – Plan routes to maximize efficiency
3. Boss impatience – Most boss deaths come from greed, not difficulty
4. Poor boundary management – Not unlocking key progression points
