Pro Tips for Coop Success
Coordinate Turn Order
Plan your turn sequence. Tanks go first to establish defense, supports second for buffs, damage dealers last to finish enemies.
Communicate Constantly
Use voice chat or quick messages. Call out when you're taking damage, when you need healing, or when you're setting up a big combo.
Share Resources
Some relics and cards benefit the whole team. Prioritize picking up party-wide buffs and distribute potions strategically.
Focus Fire
Concentrate damage on one enemy at a time. Reducing enemy action economy is crucial in harder content.
Balance Offense & Defense
Don't all go full damage. At least one player should focus on block generation to prevent team wipes.
Adapt to Relics
Let your relic drops guide your strategy. If you find party-wide buffs, lean into that synergy.
