Support — Red Mage / White Mage
King of Hearts is a Cardian, one of the magical card-soldier automatons created by the Federation of Windurst. Cardians are animated playing cards brought to life through Windurstian magic, and they serve as soldiers and servants throughout the nation. King of Hearts appears during the Chains of Promathia storyline and is notable for being more self-aware than most Cardians.

King of Hearts is a tier-upgradeable trust. Upgrading turns him from a solid support into a top-tier Red Mage buffer with Refresh III and Temper.
| Tier | Unlocks |
|---|---|
| Base | Full RDM/WHM toolkit above, +20 Fast Cast. |
| Tier I | Refresh III spell added, +30 Fast Cast total. |
| Tier II | +40 Fast Cast total, +20 MND. |
| Tier III (MAX) | Temper spell added (party-wide Multi-Strikes buff), +50 Fast Cast total. |
These are the exact items and extra gates checked by the upgrade NPC. Trust currency is stored on your character, not in inventory.
| Tier | Currency | Trade Item | Extra Requirement |
|---|---|---|---|
| Tier I | 5 Trust Stones | 1x Duelist's Tights (RDM AF legs; item ID 15121) | None |
| Tier II | 10 Trust Gems | 1x Ayanmo Corazza (Ambuscade body; item ID 25762) | None |
| Tier III (MAX) | 5 Trust Jewels | 1x Morrigan's Cuffs (Salvage hands; item ID 14977) | None |
King of Hearts and Koru-Moru fill similar RDM-buffer roles with different specialisations — Koru-Moru brings Dispel/Slow/Distract, King of Hearts brings more cleanse (Erase + -na suite), native Phalanx, and at Tier III the rare party-wide Temper buff. Use either as your main support; both at once is overkill unless you're stripping multiple enemies.
