How to Beat the Dungeon 1 Boss
Defeat your first One More Delve boss with this step-by-step guide.
The Dungeon 1 boss is your first major challenge in One More Delve. Unlike regular enemies that go down in a few swings, the boss requires a structured approach. This guide covers everything you need to defeat it.
Boss Overview
The Dungeon 1 boss has the following characteristics:
- High health pool relative to regular enemies
- Attack pattern cycles (3-5 attack combo followed by vulnerability window)
- Spawns adds (regular enemies) at approximately 50% health
- Rewards a boss chest with guaranteed blueprint drop upon defeat
Loadout Recommendation
For your first boss fight:
- Sword and shield (melee build)
- One fire or lightning spell on your right hand
- 3 health potions minimum
If you have crafted any weapon upgrades, equip them before entering.
The Fight — Phase by Phase
Opening Burst
Walk through the boss room entrance. The boss has a brief intro animation before becoming active. Use this window:
- Cast your full mana pool immediately.
- Your spells will deal approximately 30-40% of the boss’s health in this opening burst.
- Switch to your melee weapon as soon as mana is depleted.
Sustained Combat Phase
The boss cycles through attack patterns. Each combo:
- Watch the boss wind up.
- Raise your shield.
- Block the combo.
- When the combo ends, you have a 2-3 second window to attack.
- Repeat.
Critical: Do not overcommit. If you are mid-swing when the boss starts a new combo, you cannot block.
Add Phase (50% Health)
At approximately 50% health, the boss spawns 2-4 regular enemies. Priority:
Solo: Deal with the adds first if they are close to you. Use your spell for quick burst if you have mana remaining. Let the boss tank itself.
Co-op: Assign one player to handle adds while the others continue boss damage.
Final Push (20% Health)
The last 20% of the boss health is the most dangerous. The boss becomes more aggressive. Maintain shield discipline — do not get greedy for extra swings.
If You Die
You return to the hub with your banked loot intact. Your carried loot is lost. Craft better gear and try again. Each attempt teaches you more about the boss’s attack timing.

Frequently Asked Questions
Quick answers to the most common questions about One More Delve.
Can I use magic exclusively for the boss?
Yes, but your mana pool is not large enough to kill the boss with magic alone. You will need to switch to melee once mana is depleted. Magic is for burst, melee is for sustained damage.
What happens if I accidentally hit an add while fighting the boss?
Your weapon can hit adds during the boss fight. This is fine — eliminating adds reduces your risk of being surrounded. Focus fire on whichever target is closest.
Should I save a health potion for the add phase?
Save at least one potion for emergencies. The add phase is when most deaths occur because players get surrounded while focused on the boss.
