魔力歌謠

Song of Mana is a 4-mana Mana card that deals 21 damage to all enemies, with damage scaling based on how much mana you hold at the moment of play. It uniquely generates mana while also dealing scaled AoE damage, making it both a mana-engine card and a board-clearing finisher. In Arca's mana-focused builds, it is considered one of the three essential "trinity" cards.

• Effect: 21 damage to all enemies (mana-scaled) + mana generation
• Mana Cost: 4
• Color: Purple (Mana)

Combine Song of Mana with Skull O'Maniac to evolve it into Mannajja. The evolved form dramatically amplifies the mana-scaling multiplier, producing far higher damage from the same mana pool. Skull O'Maniac also raises Luck as a standalone passive, providing independent value.

• Arca's passive: Arca naturally generates +3 bonus mana, directly boosting Song of Mana's scaling baseline well above what other Crawlers achieve.
• Sharp Mind arcana: Carry up to 5 mana between turns. Banking mana on setup turns and spending it all on a Song of Mana turn is the core payoff loop for this build.
• Mana Syphon: Permanent mana ceiling increases raise Song of Mana's scaling cap continuously throughout the run — damage grows without bound in long games.
• Chain Link: Keeps combos alive across turns. Pairing this with a mana-banking strategy ensures Song of Mana fires at maximum scaling at the end of every major combo turn.

Arca is the definitive Song of Mana pilot. The "Arca Trinity" build — Arca, Song of Mana, and two complementary mana arcana — is widely considered one of the strongest archetypes in the game. Other Crawlers can use it in deep mana-engine builds.

Cost-4 mana-scaling AoE finisher. Sits at the end of the mana staircase and converts banked mana into massive board damage.

Rare pre-evolution finisher with top-tier power. The backbone of Arca builds and one of the most community-endorsed cards in Vampire Crawlers.
