General Boss Strategy

Every boss in One More Delve has unique attack patterns, but they share a common tactical framework. This guide covers the universal principles that apply to all boss fights, regardless of which dungeon level you are tackling.

The Universal Boss Loop

Boss encounters follow a predictable structure:

Phase 1: Opening Burst (0–20% health)

The boss starts with a brief intro animation. Use this window for maximum damage:

• Cast your full mana pool immediately.
• Do not hold back — the mana is useless if you die.
• Melee players should close distance and start swinging.

Phase 2: Sustained Combat (20–80% health)

The main body of the fight. The boss cycles through attack patterns with windows of vulnerability between combos.

Key tactics:

• Count the boss’s attack combo. Most bosses have a 3–5 attack combo.
• After the final attack, the boss is vulnerable for 2–3 seconds.
• Do not overcommit. If you are mid-swing when the boss starts attacking again, you cannot block.
• Keep your shield up during the boss’s active attack phase.

Phase 3: Final Push (80–100% health)

Many bosses spawn additional enemies at low health. Do not ignore these adds:

• In solo: prioritize adds that are closest to you. Let the boss tank itself.
• In co-op: one player handles adds while the other continues boss damage.

Positioning

Never stand still during a boss fight. The most common death cause is being cornered against a wall. Keep the boss between you and the room’s center. Maintain enough space to sidestep every attack.

Co-op Specific Notes

In three-player groups:

• Tank holds front and baits the boss’s attacks.
• DPS stays behind the boss for backstab bonuses where applicable.
• Mage handles adds and provides burst during tank’s cooldown windows.
