Harvest Jack

Last Updated: April 6, 2026

Harvest Jack Overview

Harvest Jack’s buff greatly improved his reliability as a control specialist, combining full buff removal, Block Buffs, and Decrease ATK with strong crowd control through True Fear, Turn Meter reduction, and passive buff suppression, making him far more effective against buff heavy enemies in both PvE and PvP.

The Lord of Terror returns with a buff that turns his enemies’ nightmares into reality, bringing a more reliable skill set than before. Harvest Jack joined the Undead Hordes as part of the Halloween 2019 Fusion event, released alongside champions such as Brakus, Madame Serris, and Miscreated Monster.

Harvest Jack’s most impactful change comes with his A2. The skill now removes all buffs from enemies, places both Decrease ATK and Block Buffs, and then grants him an Extra Turn to follow up with another ability. This is a significant upgrade from the previous conditional buff swap, giving a far more reliable way to counter buff heavy encounters. It greatly improves his effectiveness against bosses like Hydra and Amius, while also helping him shut down dangerous waves that rely on stacking buffs.

The A3 has also been updated, most notably increasing the duration of True Fear to 2 turns, while adjusting the Turn Meter reduction to 30%. This further strengthens Harvest Jack’s ability to control enemies, as targets who receive True Fear will also be placed under Decrease Speed, while those who resist the debuff will instead recieve an irresistible Sleep.

The theme of buff manipulation continues through his passive. Whenever an ally is attacked, there is now a 50% chance to decrease the duration of buffs on the attacker, increasing to 100% if Harvest Jack himself is hit. This can create a constant cycle of wearing down buff heavy targets, especially when combined with his A1 and A3, which provide additional buff removal and stealing.
