Mobile Legends X.Borg guide: Best build, skills, emblem and combos

X.Borg is one of the most aggressive and durable fighters in Mobile Legends, perfect for players who like to dive in, cause chaos, and walk out alive. Thanks to his Firaga Armor, he’s incredibly hard to kill early on, shrugging off poke damage while burning down enemies with his true damage. His skill set is built for sustained fights — he zones enemies with fire, controls objectives with ease, and can reset his armor to stay in the fight longer than most heroes.

What truly makes X.Borg terrifying is his ultimate, Last Insanity. Not only does it deal massive damage in a wide area, but the lower your enemies’ HP, the deadlier it becomes — making him a huge threat in late-game teamfights. In this guide, we’ll cover X.Borg’s strongest build, best emblems, skill progression, and powerful combos to help you dominate every phase of the game and become an unstoppable force on the battlefield.

X.Borg Skills Overview in Mobile Legends

Passive – Firaga Armor

X.Borg’s passive makes him one of the tankiest laners in the game. His Firaga Armor gives him an extra layer of HP based on a percentage of his max health, absorbing all damage until it’s destroyed. When the armor breaks, he automatically rolls in the joystick’s direction, giving him a built-in escape. He’s immune during this animation, and turret aggro instantly resets — meaning tower dives in the early game are often in his favor. As he deals fire-based damage, enemies heat up gradually. Once they reach the max temperature, they start taking true damage and drop Firaga Supplies. These supplies help restore X.Borg’s armor when he’s armored, or replenish energy when he’s in his Armorless State.

Skill 1 – Fire Missiles

This is X.Borg’s primary damage skill. He blasts fire in a cone, dealing continuous physical damage. If enemies are fully heated, the skill converts into true damage, melting even tanks. When he’s in Armorless State, Fire Missiles becomes a narrower but longer flame stream, though it does deal slightly less damage. One bonus tip: Fire Missiles won’t be visible if cast from inside a bush, so sneak up during the laning phase for surprise poke. Keep in mind that airborne, frozen, or other forms of hard crowd control can interrupt it.

Skill 2 – Fire Stake

Fire Stake sends out burning stakes in a wide fan-shaped area that pull enemies back toward X.Borg after a short delay. The stakes also retrieve any Firaga Supplies they pass through. When X.Borg is armorless, this skill has a longer range and tighter pull, which makes it perfect for collecting dropped supplies in one go and instantly recovering his armor. You can activate Fire Stake while using other abilities, including Fire Missiles and his ultimate, making it super flexible in team fights.

Ultimate – Last Insanity

This is X.Borg’s signature finishing move. He dashes forward while spinning and breathing fire, damaging and slowing enemies along the way. If he runs into a target, they take even more slow. After a few seconds, his armor explodes for massive true damage based on the enemy’s missing HP — ideal for clutch kills or wiping low-health enemies in team fights. After the explosion, X.Borg rolls in your joystick’s direction and becomes armorless, but cleanses all debuffs. Keep in mind that if the armor gets destroyed before it explodes, it only deals half damage. This move is high-risk, high-reward — use it smartly and make sure you’re not diving alone unless you’re sure of the kill.

How To Play X.Borg In Mobile Legends

Best Battle Spell for X.Borg

Flicker is easily the top choice for X.Borg, and for good reason. It adds a much-needed layer of mobility to his kit, helping him either dive in for a perfect Last Insanity or escape sticky situations when his armor breaks. Since X.Borg doesn’t have a built-in dash (outside of his passive roll), Flicker gives you the freedom to reposition during fights, chase down low-health enemies, or make bold plays under turret and get out safely. It’s especially useful for landing your ultimate on multiple targets by closing the distance instantly. Whether you’re looking to finish kills or survive aggressive trades, Flicker fits perfectly into X.Borg’s playstyle.

Best Emblem Setup for X.Borg

The Fighter Emblem is the go-to pick for X.Borg, giving him the perfect balance of damage and sustain. It enhances his durability in team fights and boosts his ability to stay in the lane without constantly needing to recall. The spell vamp from this tree works incredibly well with X.Borg’s skill-based damage, letting him recover a good chunk of HP during trades or team fights. Adding hybrid defense further strengthens his resistance against both physical and magic attacks, which is especially useful during the early game when he’s more vulnerable without his full armor and items.

For talents, start with Thrill to increase your adaptive attack and ramp up early damage. Go for Festival of Blood in the second tier — it’s a game-changer if you can start collecting stacks quickly, giving you massive lifesteal the deeper the game goes. Finish with Brave Smite as your core talent. This lets X.Borg restore HP every time he hits with a skill — and with Fire Missiles having such a short cooldown, you’ll constantly be healing in the middle of fights. This emblem setup makes him tough to take down and a real threat in extended skirmishes.

Best Build for X.Borg in Mobile Legends

X.Borg excels in drawn-out fights where he can maximize his damage over time and healing potential, so his ideal build focuses on sustain, durability, and a bit of offensive punch. For early aggression, start with War Axe — it boosts your damage as the fight goes on and helps stack your passive quicker. Pair it with Bloodlust Axe to give X.Borg reliable spell vamp, keeping his HP up during continuous skill spam, especially in the early and mid-game.

If you’re up against counter picks like Gloo or Paquito who can shut down X.Borg’s mobility or sustain, consider picking up Immortality early. The resurrection effect often makes the difference between a clutch survival and a wasted ultimate.

From there, your build should adapt to the enemy lineup. Dominance Ice is a strong choice against healing-heavy comps, applying anti-heal and reducing attack speed. Hunter’s Strike is another great situational item, giving X.Borg extra physical penetration and a movement speed bonus to help him stick to targets. Finally, round things off with Oracle, which enhances all forms of healing and shield effects — perfect for boosting X.Borg’s survivability in long team fights.

Recommended X.Borg Build:
• Warrior Boots
• War Axe
• Bloodlust Axe
• Immortality
• Dominance Ice
• Oracle

This setup makes X.Borg a frontline monster — hard to kill, constantly healing, and dishing out damage nonstop. Want help with situational item swaps or matchups next?

Best X.Borg Combos to Master

X.Borg’s strength lies in his ability to wear enemies down with constant pressure and finish them off when they’re most vulnerable. In the laning phase, your goal should be to spam Fire Missiles as often as possible to build up heat on your opponent. Once their temperature maxes out, you’ll start dealing true damage — making it harder for them to trade back and often forcing them to recall early. Keep applying this pressure to dominate your lane and build an early lead.

When the enemy’s HP is low and their temperature is full, that’s your window to finish them off. Activate Last Insanity to dive in and secure the kill. If they try to escape with Flicker or a dash, don’t hesitate to use your own Flicker to chase and detonate right on top of them for maximum damage.

In team fights, you can also flip the script and start with your ultimate — especially when paired with a tank or initiator who can group enemies for you. Dive in with Last Insanity, deal as much AoE damage as possible, and if the enemy survives, use the joystick roll after detonation to reposition. If you’re in danger, instantly Flicker out to avoid getting picked off in your Armorless State.

The key to mastering X.Borg is all about managing enemy heat levels, timing your ultimate, and knowing when to back off. Learn to flow between pressure, burst, and disengage, and you’ll turn every fight into a calculated win. Want a visual combo breakdown or advanced matchup tips next?
