Multiplayer Feature System Mechanic Player Impact & Benefit
Party Size Limit Strict 2-Player Maximum Balanced specifically for tight Souls-like combat encounters.

Hosting a Session

1. Church War Table Portal

1. Approach the Church War Table and press the Expedition Party prompt.
2. Select "Host Private Room".
3. You will receive a 6-digit Sanctum Code (e.g., CM-4892) or you can directly invite a friend through the Steam Overlay (Shift + Tab).

Joining a Partner

2. Joining via Code

1. From the Main Menu or Church hub, select "Join Sanctum".

Downed State, Revive Costs & Bleedout Rules

Understanding how the revival system works is the key to preventing full party wipes during multi-phase Dead Gods encounters:

Multiplayer State Duration / Condition Cost to Revive Recommended Action
Downed (Crawling) 15-Second Bleedout Timer Free movement while crawling Crawl behind cover or away from active boss AOE zones immediately.
Standard Revive 3.5-Second Channel Interaction 1 Alchemist Flask Charge Restores teammate with 50% Max HP and 2 seconds of invulnerability.
Emergency Blood Revive If out of Flask charges 30% of Reviver's Current HP High-risk clutch play; only attempt if boss aggro is clear.
Party Wipe Both players downed simultaneously Run failure; lose all unbanked Souls Stagger your defensive cooldowns so both players never commit together.
Pro-Tip: Sunder Transformation as a Revive Shield

Channeling a revive leaves you vulnerable to enemy attacks. However, activating Sunder Form grants full poise hyper-armor. Pop Sunder right before reviving to power through boss sweeps without being interrupted!
