X.Borg MLBB Guide: Best Build, Emblem, Combos, and Counters

X.Borg is a Fighter who wins long fights by heating targets with Fire Missiles, recovering Firaga Armor through supplies, and detonating Last Insanity after enemies have already lost HP. Pick him into short-range front lines that must stay near a wave or objective. Avoid drafting him as the only reliable engage against mobile back lines that can break armor and keep distance from the real body.

Quick Answer: X.Borg's Winning Plan

Role, Specialty, and Level-One Stats

X.Borg is listed in-game as a Fighter with Regen/Burst. His true durability is split between Firaga Armor and the real body, so one HP value never tells the whole story. The base-stat panel shows no Mana resource, which makes Impure Rage restore HP instead of Mana when its current condition is met.

X.Borg Skills and Practical Use

Firaga Armor

Passive / Buff

Firaga Armor inherits 160% of X.Borg's Max HP and takes all incoming damage while active. Losing it triggers an invulnerable roll, then armor energy rebuilds until he can re-equip at 30% HP. Overheated enemies drop Firaga Supplies, and skills deal True Damage to them.

Use it well: Treat the armor bar as a second tempo meter. Collect supplies during safe burn cycles, and angle the armor-break roll toward cover or your team instead of deeper into the fight.

Avoid: Do not spend the real body as if the armor break guarantees safety. Hard control or burst waiting after the roll can still finish X.Borg before the suit returns.

Fire Missiles

Skill 1 / AOE

X.Borg sprays fire seven times over two seconds. The current panel starts at 25 base Physical Damage per hit, uses both Physical Attack and Magic Power scaling, and deals reduced damage to minions. Armorless range is longer and narrower, with damage reduced to 60%.

Use it well: Keep the cone tracking across the target until the heat meter completes. Walk sideways with melee fighters, using the moving cast to kite rather than standing still for a perfect line.

Avoid: Do not aim only at the target's current position. Lead the cone toward the escape route, and stop chasing when doing so would expose the unarmored body.

Fire Stake

Skill 2 / CC

X.Borg fires five stakes and recalls them after 1.7 seconds. Each stake deals Physical Damage and pulls enemies and Firaga Supplies back along its path. Armorless State gives the stakes more reach and a tighter spread.

Use it well: Cast while Fire Missiles or Last Insanity is already active. Pulling supplies into X.Borg during a burn often restores enough armor or energy to survive the next exchange.

Avoid: Do not treat the outward stakes as the whole skill. Place them so the return path crosses the target, a supply pile, or the route an enemy must use to disengage.

Last Insanity

Ultimate / Burst / Mobility

X.Borg charges while spinning and spraying fire, hitting repeatedly and slowing enemies. Contact with a hero adds a stronger slow. After three seconds the suit explodes for 300 plus 15% of the target's Max HP as True Damage; an early armor break halves that explosion. Recast detonates early.

Use it well: Start only with armor available and a clear exit after the blast. The best target is already heated, missing HP, and committed near teammates or terrain that limits escape.

Avoid: Do not open every fight with the ultimate. It deliberately destroys Firaga Armor, so a low-value detonation can leave X.Borg exposed while the real enemy damage is still ready.

Skill Upgrade Priority

Learn Fire Missiles at level 1 and prioritize it, with Fire Stake as the secondary upgrade. Level Last Insanity whenever available. This order matches both roles: Fire Missiles is the main clear, heat, and pressure tool, while Fire Stake makes that pressure reliable by pulling enemies or Firaga Supplies back through the active burn.

Best Emblem and Battle Spell

For the current jungle-oriented setup, use the Custom Fighter Emblem with Thrill, Seasoned Hunter, and Impure Rage. Thrill adds Adaptive Attack for early clear and skirmishes. Seasoned Hunter improves Lord and Turtle damage, which is valuable only for the team's actual Retribution user. Impure Rage adds periodic skill damage; because X.Borg has no Mana bar, its recovery returns HP instead.

Take Retribution in Jungle and match the boot blessing to the draft. Ice Retribution helps keep a target inside Fire Missiles, while another blessing can be considered when the team already has enough slows. For EXP Lane, use Fighter Emblem with Firmness, Festival of Blood, and Brave Smite when sustained front-line value matters most. Flicker extends ultimate angles and gives the armorless body an exit; Vengeance is stronger when the enemy must commit damage into you for several seconds.

Equipment Guide

Use the item notes below to decide what each slot contributes. The table describes each item independently of the numbered builds.

Item	What it adds	When to consider it
Tough Boots	Movement Speed and Magic Defense, plus shorter crowd-control and slow duration.	Default into reliable crowd control or magic pressure. Move to Rapid Boots only when access and rotation speed solve more problems than Magic Defense.
War Axe	Physical Attack, HP, cooldown reduction, and hybrid lifesteal; long fights build Fighting Spirit and reward repeated Fire Missiles hits.	Buy early when X.Borg can remain in contact long enough to stack it. Delay only for urgent anti-heal or a defense needed to survive the first objective fight.
Sky Piercer	Adaptive Attack and movement, with a low-HP execution effect that becomes more threatening after successful takedowns.	Use when the team needs X.Borg to convert low-HP targets after the burn and ultimate. Skip it when surviving the first enemy burst is the real win condition.
Immortality	HP and Physical Defense, plus a delayed resurrection and temporary shield on a long cooldown.	Move it earlier before decisive Turtle, Lord, or base fights. Replace it while the resurrection passive is unavailable if another defense answers the next engagement better.
Brute Force Breastplate	HP, Physical Defense, and stacking movement or defensive value while X.Borg keeps attacking and casting.	Buy against sustained physical pressure when Fire Missiles can keep stacks active. Choose a specialized magic defense item when spell burst is the main threat.
Ice Queen Wand	Magic Power, HP, spell vamp, and a skill-hit slow that helps Fire Missiles keep targets inside the cone.	Buy when the draft lacks slows and enemies keep stepping out of Fire Missiles. Skip it when teammates already provide enough control and X.Borg needs pure durability.
Rapid Boots	Higher rotation speed and strong slow resistance for reaching camps, lanes, and objectives sooner.	Choose for faster jungle routes and drafts built around slows. Replace them when chain control or magic burst can remove the real body after armor breaks.
Dominance Ice	Both defenses and nearby anti-sustain pressure, reducing enemy shields and HP recovery during close fights.	Choose against healing, shields, or fast Basic Attacks, especially when X.Borg can stay close enough to maintain its pressure.
Oracle	HP, both defenses, cooldown reduction, and stronger healing or shielding received during repeated armor cycles.	Choose when extra recovery and mixed defenses stretch Firaga Armor cycles. Prefer concentrated resistance if one enemy damage type is ending fights instantly.

X.Borg Combos

Teamfight burn and detonation

Fire Missiles → Last Insanity → Fire Stake. Start the heat and force enemies to choose a direction, then spin through the group once they cluster. Fire Stake can be cast during the ultimate, pulling enemies and nearby supplies back into the path. Detonate early only to secure a low target, dodge the wrong return angle, or avoid losing the armor before the larger explosion.

Laning pressure

Fire Missiles → Fire Stake. Walk with the cone rather than planting X.Borg in place. Place the stakes beyond the target or around dropped supplies so the return path crosses both. Against a dash hero, keep Fire Stake until after the first movement skill instead of throwing both abilities into empty space.

How to Play X.Borg by Game Phase

Five X.Borg Mistakes to Avoid

1. Using Last Insanity before targets are heated. The spin looks threatening, but a healthy mobile enemy can leave while X.Borg gives up his armor.
2. Ignoring Firaga Supplies. Fire Stake can retrieve supplies during another skill, often changing whether the next hit breaks armor or restores the suit.
3. Chasing in Armorless State. Longer Fire Missiles range is useful for spacing, not permission to follow a target through unseen enemies.
4. Buying every damage item from a winning build. Sky Piercer is valuable only when X.Borg can survive long enough to create low-HP targets; a timely defense may produce more damage over the full fight.
5. Taking Retribution outside the jungle plan. Seasoned Hunter and jungle boots are role-specific. EXP Lane usually needs Flicker or Vengeance to solve fight access or survival.

Counters and Team Synergy

Favorable matchups

Terizla and Aulus must spend time in close range. Kite their first commitment, keep Fire Missiles moving, and use Fire Stake to deny a clean disengage.

Hard matchups

Martis and Dyrroth can burst through armor and threaten the real body. Do not trade the suit merely to start a neutral fight; wait for their strongest commitment or bring defensive help.

Best partners

Karina and Martis can finish targets left low by repeated burns. X.Borg supplies area pressure while they convert the health advantage into kills.

Draft warning

Benedetta illustrates the problem with highly mobile compositions: she can leave the cone, avoid the pull line, and re-enter after X.Borg loses armor.

X.Borg Story

X.Borg confronts Dr. Rooney after burning down the scientist's laboratory, accusing him and Eruditio of lies that ruined lives in the name of progress. The monologue frames X.Borg as the Nightmare of Eruditio: a survivor who sees his mechanical body, the flames, and the destroyed lab as a rebirth rather than a loss. Dawn arrives over the ashes as he refuses Rooney's explanations and embraces revenge.

X.Borg FAQ

What is the best X.Borg build?

War Axe is the shared early core in the five current builds. A jungle damage path can add Sky Piercer, Ice Queen Wand, Brute Force Breastplate, and Immortality. Use Dominance Ice when enemy healing or shields decide fights, and Oracle when stronger recovery and mixed defense will extend armor cycles.

What is X.Borg's best emblem?

For Jungle, use Custom Fighter Emblem with Thrill, Seasoned Hunter, and Impure Rage. For EXP Lane, Firmness, Festival of Blood, and Brave Smite create a steadier sustain setup. Do not take Seasoned Hunter when another teammate is the actual Retribution user.

Should X.Borg use Retribution, Flicker, or Vengeance?

Retribution belongs to the jungle route. Flicker is the flexible EXP choice for ultimate angles and escape after armor breaks. Vengeance is the front-line alternative when the enemy must keep attacking X.Borg during the same extended exchange.

When should X.Borg detonate Last Insanity?

Detonate after targets are heated, missing HP, and committed near teammates or terrain. Recast early only when it secures the result or prevents a worse armor break; every explosion leaves X.Borg in Armorless State.

Who counters X.Borg?

Martis and Dyrroth threaten quick armor breaks and strong follow-up on the real body. Highly mobile heroes also make it hard to complete Fire Missiles heat. Preserve Fire Stake for their movement and avoid starting from open ground.

Final Verdict

Pick X.Borg when the enemy must fight in one place and your team benefits from a long, messy health advantage. The reliable version of the hero is patient: heat with Fire Missiles, collect supplies, pull with Fire Stake, and detonate only when the fight has already become difficult to escape. Build enough defense to finish the sequence, then use damage or slow items to convert that time into kills.
