Co-op Guide — 4-Player Team Strategies & Coordination

Co-op in Sephiria

Sephiria supports 1-4 player online co-op. In co-op, enemy health and damage scale with player count — and so do rewards. Coordination separates a successful team from a wipe.

How Co-op Scaling Works

• Enemy health and damage scale with player count — a 4-player lobby faces a significantly tougher tower than solo
• Solo is fully balanced and viable — co-op is an option, not a requirement
• Rewards scale with the party, so there's no penalty for playing together

Optimal Team Composition

A well-balanced 4-player team covers all situations. The roles below are the community-consistent setup:

Recommended 4-Player Setup

Role	Weapon	Responsibility
---	---	---
Frontline	Sword & Shield (or Greatsword)	Hold the line, block attacks aimed at the team, revive safely
Ranged DPS	Crossbow	Sustained single-target damage, pick off elites from range
AoE / Control	Staff	Room clear, element coverage, layered damage
Flex / Support	Any — matches team needs	Add control, utility artifacts, revive guard

2-Player Recommended Pairs

Pair	Synergy
---	---
Sword & Shield + Staff	Frontline holds aggro while the Staff AoEs freely
Crossbow + Sword & Shield	Safe ranged damage plus a wall that never dies

3-Player Note

A frontline + ranged DPS + AoE composition covers every boss encounter — the three core roles are more important than having all four filled.

The Revive System

When a teammate's HP hits zero, they enter a downed state:

• A revive prompt appears above their body
• Reviving is a short interaction — you must hold it uninterrupted
• Enemies can hit you during revive — the team must clear space
• If fully killed (HP depletes during the downed state), they are eliminated for the current room

Revive Priority

1. Frontline revives DPS — the tank has the HP to absorb hits during the revive window
2. Support covers the reviver — keep the area clear while the revive happens
3. Assign a revive guard in boss fights — one player's job is covering the downed teammate

Communication is Key

Pre-Run Planning

Before entering the tower, decide:

1. Who covers which role — frontline, ranged DPS, AoE, revive guard
2. Boss fight roles — who holds the boss, who clears adds, who guards revives
3. Loot distribution — who gets priority on which artifacts

In-Run Callouts

Essential callouts in co-op:

• "Down!" — You're downed, need a revive
• "Secret room!" — Hidden room found
• "Elite!" — Strong enemy spotted
• "Shop!" — Vendor found, check gold
• "Boss room!" — Final room, prepare

Co-op Boss Strategies

The four co-op boss roles that apply to every fight:

Role	Job
------	-----
Frontline	Tank the boss's melee patterns — Greatsword stagger chains
Ranged DPS	Crossbow/Staff — keep damage up through barrages
Revive guard	One player covers the revive window when a teammate goes down
Add control	Clear summoned minions (Pillar Summoner fights) so the boss stays focusable

The classic bossing pair: Greatsword + Sword & Shield. One player staggers the boss, the other eats its counterattacks.

Co-op Tips That Actually Matter

• Stick together. Splitting up makes packs much harder to deal with — the scaling doesn't care about your positioning.
• The host's game state determines shop inventory — coordinate purchases so the host doesn't buy out the best items before teammates can see them.
• Potions are per-player — you can't trade them, but you can ping their locations.
• Healing effects that cover the area help everyone — position near your lowest-HP teammate.
• If you're having connection issues, see the Multiplayer Connection Fix Guide.
