Harvest Jack is a Legendary Spirit HP champion who joined the Undead Hordes as part of the Halloween 2019 Fusion event, built around buff removal and layered enemy control.
Core Strengths & Abilities
Buff Denial & Follow-Up: His A2, Dreams to Ash, is an AoE attack that strips buffs from enemies under Fear, converts their Increase ATK into Decrease DEF and Continuous Heal into Poison, then grants him an Extra Turn — letting him chain into another ability immediately, which is especially strong against buff-heavy bosses like Hydra and Amius.
Layered Crowd Control: His A3, Lord of Terror, is an AoE attack with a 100% booked chance of placing True Fear for 1 turn, which also applies a 30% Decrease SPD debuff and cuts 15% Turn Meter; targets that resist True Fear instead receive a guaranteed Sleep, ensuring some form of control lands regardless.
Passive Attrition: His passive, Leering Grin, decreases the duration of all buffs on any attacker by 1 turn whenever an ally is hit, wearing down buff uptime over the course of a fight.
Key Weaknesses
Single-Target Buff Steal: His A1, Harvest of Fear, only steals buffs and applies Fear on a single target, so his buff-stripping is mostly delivered through his AoE A2 rather than consistently across all enemies.
Harvest Jack's combination of guaranteed control and reliable buff removal makes him a strong pick for Arena, Hydra, and other buff-reliant boss fights.
