How to Beat Leshun the Entangled One

Leshun, the Entangled One, is one of the most misunderstood bosses in Grim Forest. On paper, his damage looks manageable, but his control mechanics quietly dismantle teams that aren’t prepared. Entangle shuts champions out of team support, Siphon slowly steals your stats, and his passives heavily reduce damage unless you meet very specific conditions.

The fight isn’t about raw power — it’s about understanding what can’t be cleansed, what must be removed immediately, and when to ignore mechanics entirely and just push damage. Once you know those rules, Leshun goes from frustrating to surprisingly straightforward.

This article assumes you have killed all four of the wandering bosses to remove them from the Leshun fight. If not, this fight becomes a lot more complicated. However, we will try to complete a guide in the next rotation to face all 5 bosses simultaneously.

Entangle is not a normal debuff

Entangle is the defining mechanic of the fight. A champion under Entangle cannot receive positive effects from allies, including buffs and healing, and their Turn Meter will not increase passively. The debuff cannot be cleansed, resisted, blocked, redirected, or have its duration modified in any way.

The only way to remove Entangle is by actively filling the champion’s Turn Meter to 100%. This is why Increase Turn Meter effects are so important here. If you don’t have a way to push Turn Meter, Entangle becomes permanent for that champion.

Because of this, it’s often correct to let one champion stay Entangled if they aren’t essential to your win condition.

Siphon is the real danger

Siphon is placed on the fastest champion and steadily steals stats, making Leshun stronger while weakening your team. Unlike Entangle, Siphon can and should be removed. Leaving it active for even a few turns dramatically increases the difficulty of the fight.

If there is one mechanic you should treat as an emergency, it’s Siphon. Cleanse it immediately and repeatedly.

HP Burn unlocks the fight

Leshun’s defensive passives drastically reduce the damage he takes and can even convert critical hits into weak hits. HP Burn disables these defences and makes him far more vulnerable.

With HP Burn active, your Turn Meter effects are more impactful, and your damage becomes consistent. Without it, the fight drags on and gives Entangle and Siphon more time to overwhelm you.

The most important decision happens before the fight even starts: who is your fastest champion?

Leshun targets speed, so if your fastest unit is your only cleanser or your primary support, they are very likely to be Entangled or Siphoned early. This can cripple your run before it begins.

Ideally, your fastest champion is either expendable or self-sufficient, or you have a second support who can function if the first one is shut down.

Once the fight starts, your priorities should be clear. Remove Siphon as soon as it appears. Get HP Burn onto Leshun as early as possible. If a key champion is Entangled, push their Turn Meter to free them — otherwise, it’s often fine to ignore the Entangle and continue playing around it.

Trying to cleanse Entangle or waiting for it to expire will never work. The fight becomes much easier once you stop fighting that mechanic directly.

Leshun is not a boss you brute force through his defensive state. The cleanest damage windows happen after HP Burn is active and Siphon has been removed. That’s when Decrease DEF, damage passives, and nukes start to matter.

If you push damage too early, you’ll waste turns and risk getting dragged into repeated Entangle and True Fear cycles. Slow the fight down, stabilise the mechanics, then end it decisively.

Instead of thinking in terms of specific champions, think in roles. You need a consistent HP Burn source, at least one cleanser to handle Siphon, and some way to increase Turn Meter to free Entangled allies when necessary. Damage comes last — once the mechanics are under control, most reasonable damage dealers can finish the job.

Block Debuffs, Decrease Speed, and Decrease Defence all help smooth the fight, but they’re secondary to handling Entangle and Siphon correctly.

Most failed runs come down to the same issues: ignoring Siphon for too long, bringing no Turn Meter boosts, relying on cleansing to deal with Entangle, or putting all essential utility on the fastest champion. Fixing any one of these usually makes an immediate difference.

If Leshun feels overwhelming, it’s usually a preparation issue rather than a damage problem. Once you accept that Entangle is something you work around rather than remove, and you treat Siphon and HP Burn as the real levers of the fight, Leshun becomes one of the more predictable bosses in Grim Forest.
