Priority: Top Tier (for high-cost card builds)

Cooldown is one of the most impactful upgrades for builds that rely on 3–5 mana finisher cards like Hellfire, Phieraggi, or Vandalier. More max mana means the combo staircase can reach higher-cost cards every turn.

Recommended Builds

High-cost finisher builds:

Phieraggi (4 mana), Vandalier (5 mana) — max mana is essential for consistent access
Extends how far the combo staircase can go per turn

Mana generation builds:

Pair with Sharp Mind arcana — the carry-over cap increases in effective value
Tome cards (Empty Tome through Ancient Tome) produce more mana per turn when you have higher max mana to spend

Synergies

Arca Crawler: +3 Mana ability — Cooldown lets you use that mana more aggressively
Christine Crawler: Mana cost -1 on hand cards — combo with Cooldown for cheaper high-cost cards
Sharp Mind arcana: carry up to 5 mana between turns — max mana increase amplifies carry-over value
Mana Syphon arcana: permanent mana gains stack with Cooldown for compounding mana growth
Mana Rebate gem: mana returning to 0 gives double mana — higher max mana makes this proc more impactful

Notes

At 3,500 coins, this is a mid-to-late game purchase
Buy high-cost cards before this upgrade — the upgrade only pays off if you have cards that need the extra mana
Pairs well with Mana Rebate gem
