X.Borg

Pick him when the lane has to stand still

X.Borg is best when the fight has to happen in one place. Slow front-to-back comps, melee bruisers who must walk through the wave, and tank junglers who contest Turtle from inside the pit all give him the kind of battlefield he wants. If the enemy has to keep stepping into Fire Missiles just to play the game, X.Borg is already doing his job before the kill even happens.

He is much worse as a blind first-phase EXP pick than people pretend. The hero stops feeling oppressive the moment the enemy lane can break armor fast and re-engage while you are armorless. Esmeralda is still a clean answer because Firaga Armor is exactly the kind of shield she wants to steal. Chou and Gloo are also bad signs because they either force you out of your spacing or punish the moment your first bar disappears. Recent player consensus points the same way on mobile burst lanes: Benedetta, Paquito, Yu Zhong, Dyrroth, and similar EXP picks become difficult because they do not stay inside your burn long enough for the trade to tilt back your way.

Pick X.Borg when your team already has real lockdown from roam or mid and needs a durable damage source to own the river mouth around objectives. Avoid him when your draft needs the EXP lane to start every fight by itself, or when the enemy has already shown two heroes who can strip armor on first contact. If you cannot answer the question "who is forced to stand in my fire?" then X.Borg is the wrong lock.

X.Borg is a temperature check, not a diver

The mistake most players make on X.Borg is treating him like a fighter-assassin with an explosive ultimate. He is not. He is a temperature check.

Everything in the kit points to the same loop. Fire Missiles is there to keep people inside a bad trade until their heat reaches the cap. Firaga Armor exists so you can stay in that trade longer than another EXP laner should be allowed to. Fire Stake is the leash that drags supplies back to you, clips anyone trying to sidestep the burn, and turns chip damage into another full armor cycle. Last Insanity is not the reason the hero works. It is the cash-out after the lane or fight has already been bent in your favor.

That is why X.Borg feels oppressive into players who only know how to take direct trades. He does not need to hard commit to win lane. He needs one long angle, one supply pickup, and one moment where the opponent realizes too late that leaving costs more HP than staying. If you play him like a hero who must instantly reach the backline, you spend the whole match entering armorless and dying for it.

Laning: the first 5 minutes

1. Start Fire Missiles and take the outer edge of the wave. Do not stand in front of the minions and burn the whole lane on autopilot. Hold a diagonal angle so your flame clips both the melee minions and the enemy EXP laner. The goal is not to shove mindlessly. The goal is to make every last-hit attempt come with heat attached.
2. Use Fire Stake after supplies exist, not before. Raw S2 fishing is how X.Borg players lose control of lane. Wait until the opponent has already been tagged enough to drop supplies, then pull the lane back into your space. Now the same button pokes the enemy, refills armor, and threatens another sweep if they try to punish.
3. Save Flicker for the armorless window. If you burn Flicker while Firaga Armor is still intact, you waste the hero's built-in bailout and give up your only real escape after the armor pops. Let the passive roll create the first bit of distance, then Flicker only if the enemy still has enough follow-up to kill the real body.

Your early lane plan changes with matchup quality. Into slow bruisers, keep the wave near river and keep heating them on repeat until they cannot contest the crab or first rotation. Into burst lanes that can crack armor quickly, freeze closer to your side and farm for the first item component instead of trying to prove a point. X.Borg does not need first blood to win the lane. He needs the lane to still be playable when Turtle spawns.

The two-item window you are farming toward

The cleanest X.Borg spike is War Axe plus Brute Force Breastplate, usually around the 8 to 11 minute window in a stable EXP game. Before that timing, he is annoying. After that timing, he starts deciding where people are allowed to stand.

The reason is mechanical, not cosmetic. War Axe gives him HP, cooldown reduction, spell vamp, and a passive he stacks unusually fast because Fire Missiles and Last Insanity keep dealing repeated damage. Once fully stacked, War Axe adds extra true damage on top of the normal trade pattern. Brute Force Breastplate stacks alongside it, feeding movement speed and adaptive attack every second after you deal damage. X.Borg is one of the cleanest users of both items because his whole job is to stay active in the fight instead of bursting once and backing off.

What changes when both items are done is simple: the space around you becomes expensive. You are faster at holding range, better at dragging a bad trade past the first exchange, and harder to pin down before your second bar matters. This is the first moment in the game where you should stop thinking "can I poke them out?" and start thinking "can they even walk into this objective if I arrive first?"

If the game is ugly and you are behind, there is a practical fallback. War Axe plus Immortality is worse for lane pressure, but it keeps your first objective fight alive long enough to matter. Do not confuse that fallback with the real spike. The real spike is War Axe plus Brute Force, because that is the version of X.Borg that turns chip into map control.

Teamfights are won before Last Insanity

The common wrong reflex is to see a grouped enemy team and ult straight through the middle. That looks dramatic and loses games. X.Borg wins most fights by cooking the frontline first, forcing cooldowns and movement, then cashing out with Last Insanity when the escape paths are already ugly.

1. Stand at the hinge of the fight, not on the backline path. Your best tile is the space enemy bruisers and tanks must cross to reach your carry. If you take that ground early, the enemy has to choose between eating fire or giving up the engage angle.
2. Use Fire Stake as a leash, not a prayer. Pull supplies through the fight, punish anyone trying to sidestep out of the burn cone, and keep your own armor cycle alive. S2 is strongest when it extends pressure you already own, not when it starts pressure from nothing.
3. Ult after the exit closes. Last Insanity is at its best when the target has already spent a dash, run into a wall, or stepped too deep into a choke. If you cast it as first contact, the enemy just disengages, breaks your armor early, and leaves you standing armorless in the middle of five people.

There is one important support-dependent exception. If your roam is Atlas, Tigreal, or another hard commit engager, you can press ultimate as immediate follow-up because someone else already spent the first CC and closed the door for you. If your team is playing Estes, Angela, or another sustain setup, stay front-to-back and save Last Insanity for the second wave of the fight. That version of X.Borg is harder to punish and far more consistent in solo queue.

Itemization is four locked ideas and a few real conversations

Start with the idea, not the fixed screenshot. X.Borg wants one movement choice, one core stacking item, one extended-fight amplifier, and then flex slots that answer the lobby in front of him.

Boots are matchup boots, not autopilot boots. Tough Boots is the better default into magic poke, chain CC, and drafts where getting slowed once means eating the whole collapse. Warrior Boots is better into physical EXP lanes that hit you repeatedly in small trades. If you are jungling, the Retribution upgrade changes the slot, but the same question stays the same: do you need resistance to magic and control, or repeated physical chip?

War Axe is the non-negotiable first real item. It gives HP, cooldown reduction, spell vamp, and a passive X.Borg stacks faster than most fighters. This is the item that makes every later choice make sense.

Brute Force Breastplate is the clean default second item. The HP, cooldown reduction, extra movement speed, adaptive attack, and full-stack control-duration reduction all fit exactly what his fights look like: long, sticky, and repetitive.

After that, the build becomes a conversation:

• Immortality if you need to be first body at Turtle, Lord, or a tower dive. X.Borg already forces enemies to spend time on two health states. A revive stretches that tax again and often buys the seconds your team needs to finish the objective.
• Oracle when the enemy is chipping you instead of bursting you. Bless boosts received shield and HP regen by 30%, which makes every supply pickup and every reset cycle more valuable.
• Dominance Ice when the enemy lineup is built on sustain or attack-speed carries. Lifebane cuts the attacker's shield and HP regen to 50% for a short window, and Arctic Cold punishes people who try to stat-check you with repeated hits.
• Hunter Strike when you are ahead and need chase speed more than raw durability. Reaching five consecutive hits is easy on X.Borg, so the movement burst comes online reliably in the kind of skirmish he already wants.
• Ice Queen Wand when your team lacks stickiness. Its slow turns every successful flame tag into a longer zoning window and is especially annoying against short-range carries who rely on walking out of your cone.
• Queen's Wings when the enemy plan is to crack armor, dive the body, and finish you through the reset. The low-HP damage reduction and cooldown refund are much better here than a greedier damage slot.

The bad habit is building as if every game is won the same way. X.Borg is not a six-item template hero. He is a "what makes this next fight impossible for them?" hero.

The mistakes that actually lose X.Borg games

Blind-picking him into shield drain or fast armor break. X.Borg looks safe because he has two life bars. That safety disappears against heroes whose lane pattern is built around deleting the first one on command. Esmeralda, Chou, Gloo, and the current crop of mobile burst EXP lanes all force the same bad state: armor gone, real body exposed, no clean way to hold range.

Throwing Fire Stake before the lane has supplies to steal. Early S2 misses are not just wasted poke. They remove your best way to refill armor on the next trade and signal to the opponent that they have a window to walk up. Wait until the trade is already dirty, then use S2 to make it dirtier.

Using Last Insanity as the first button in every teamfight. The spell is strongest as a punish or follow-up. When you press it too early, the enemy gets the easiest possible answer: break the armor before the detonation matters and collapse on the armorless body. X.Borg does not need his ultimate to start winning the fight. He needs it to end the argument.

Chasing the marksman through open space. You are not Hayabusa. If the enemy backline has already left your flame and is running toward clear terrain, the correct play is often to turn back, hold the choke, and keep their frontline miserable. A lot of X.Borg deaths come from confusing zoning value with kill value.

Rotating off lane without wave control. EXP X.Borg wants the first real item timing on time. If you leave lane on a bad wave, lose the next two minion crashes, and arrive late to the objective anyway, you have traded your strongest early advantage for nothing. Push first, then move. If you cannot do both, keep the lane.

Small edges that make the hero feel unfair
