A sadistic doctor working for Hyde Reaper. Hidden behind his innocent smile is a cruel soul. He dreamed of becoming a doctor because of his ability to identify the structure and weakness of anything at a glance, but he was denied a medical license because he was a demon. While practicing medicine without a license, he developed a malevolent nature and began conducting ruthless human experiments on unidentified criminals he kidnapped. He was imprisoned underground by Princess Rin but was later freed by Raise, who persuaded him to join Hyde Reaper.
Jack Guide
Best farmer + Silence AOE + Immortal
Useless in PvE combat + Situational PvP
Jack during farming session in adventure.
Jack is a specialized hero primarily used for farming efficiency. His passive aura provides a permanent movement speed boost, making him indispensable for quickly clearing farming-focused content. Outside of this, his utility in combat is limited, and he should not be relied upon as a primary damage dealer or support in serious competitive modes.
Strengths
Weaknesses
Recommended Synergies
Best Game Modes
- Farming teams — Nightmare Shard farming, resource chest farming. Primary and best use case by far.
- PvP (Arena) — highly situational — occasionally Immortal buff buys time to land Silence. Do not rely on this.
Build & Optimization
Recommended stats: Critical Hit Rate. Jack relies on crits to apply Silence on his active skill.
Investment Advice
FAQ
Is Jack worth pulling?
Yes — best farming hero in game. Essential for Nightmare Shard and resource farming efficiency.Why is Jack considered the absolute best farming hero in the game?
Jack is an essential quality-of-life unit due to his permanent passive aura, which grants a massive +50% Movement Speed to the entire team. This drastically cuts down clear times when farming campaign maps, Nightmare mode, and farming Chest stages.Do you need to invest massive resources into Jack to make him playable?
No, Jack is extremely budget-friendly. Leveling him up between levels 80 and 100 is more than enough for stage farming, even at 0 stars—just ensure that the stage monsters aren't strong enough to accidentally trigger his passive immortality. If you do want to run him in PvP, your main focus should be gearing him with Accuracy to help him land his AOE Silence.This site is a fan project and is not affiliated with, sponsored by, or endorsed by Netmarble.
