Billow — Warrior Guide
Billow is a melee warrior built for the slayer lane. He does not negotiate for space, he takes it. His kit is built around explosive burst windows, a short but punishing engage range, and cooldown-timed aggression rather than blind button-mashing. Every trade is a calculated escalation at close range, and when you read the situation correctly, you delete people who thought they were safe. He is a hit-and-dominate bruiser who wants every duel over in three seconds, not a sustained-fighter grinding away at someone's health bar.
This patch he sits at S tier, and the numbers back it up. A 26.7% pick rate and a 19.3% ban rate mean high-ranked lobbies both respect and fear him. He is not being ignored, he is being targeted in draft before anyone gets the chance to pilot him. His 50% win rate is the healthy floor of a high-pressure meta pick: he drops some games to hard counters, but wins decisively when he hits his power spikes without interference.
Diamond-and-above players should pick Billow up if they enjoy snowballing a lane lead into relentless mid-game pressure. He demands cooldown awareness and punishes anyone who disrespects those windows severely. Verify all ability numbers in-client, since exact values shift with each balance pass.
Strengths
- +Billow's burst window is one of the shortest time-to-kill sequences in the slayer lane, letting him win almost any 1v1 duel when his cooldowns are available.
- +His kit provides meaningful self-sufficiency in lane, he doesn't need a support to trade favorably, which lets your team's resources go elsewhere in draft.
- +At S tier with a 19.3% ban rate, Billow applies real draft pressure: even when banned he forces opponents to use a ban slot, effectively giving your team a pick advantage.
- +His ability to snowball a single early kill into sustained lane dominance means a good laning phase translates directly and efficiently into mid-game objective control.
Weaknesses
- −Billow is entirely cooldown-dependent, the moment his abilities are on cooldown, a patient opponent can trade back freely and win an extended fight.
- −He has limited tools for dealing with sustained poke or ranged harass in lane, meaning mage-type slayer matchups can make his early game genuinely miserable.
- −Without a meaningful lead by mid-game, Billow falls off against tankier late-game compositions that can simply outlast his burst window.
- −His engage range is short, making him susceptible to being kited by mobile carries in teamfights if the enemy draft has multiple dashes or displacement tools.
Abilities
PHunter
Billow’s passive allows him to identify vulnerable targets. When an enemy’s health is below 30%, they are considered “prey”. Billow’s basic attacks and abilities on “prey” deal 15% more true damage, giving him an advantage in teamfights and finishing off targets.
1Wavebreaker
Billow utilizes the power of the Sea Beast to increase his movement speed for 3 seconds. He then jumps out of the water and gets a 50% cooldown refund. While in Sea Beast form, this skill also allows Billow to dash out of the water, dealing physical damage and slowing the target by 50% for 1.5 seconds.In particular, if the skill is used near a river, the Sea Beast form will not have a time limit, significantly increasing the attack effectiveness. When detecting "prey" within 15m, the acceleration effect is increased by 450 points, thereby helping Billow easily approach and finish them off.
2Space Split
Billow exhibits the ability to close in and attack the target with continuous slashes, causing strong physical damage. When activated, Billow receives a mark, and each time he hits an enemy, an additional mark is added. A target can receive up to 3 marks. With each mark, Billow's attacks heal, but if the target is not a hero, the healing effect is halved.In Sea Beast form, Billow will charge forward and then slash at enemies.
RDeath From Below
He unleashes a powerful sword strike in the designated direction, slowing enemies significantly for a moment, then dashes in a wide range, dealing massive physical damage.When in Sea Beast form, his ultimate move does not require a sword strike but automatically dashes forward, while reducing the cooldown of Water Dash. With the ability to cause large-scale pressure and high damage, this skill makes Billow an extremely formidable opponent in teamfights.With flexible mobility and powerful damage from his skill set, Billow promises to become a formidable Assassin on the battlefield.
How to Use Billow's Kit
Billow's passive rewards consistent aggression by stacking or enhancing his damage output as he engages, likely through a buff tied to auto-attack chains or ability hits. The common mistake at Diamond rank is letting the passive stack decay by retreating too early after an engage; commit to the trade long enough to get full value, then back off. Managing this as an internal cooldown or buff window is the core micro habit that separates good Billow players from great ones.
This is almost certainly Billow's primary gap-closer or damage-enhance ability, and it should be used as the entry point of every trade rather than mid-combo, opening with it ensures you're in range to chain the rest of your kit. A common error is using Q reactively as an escape; in most situations Billow has far better tools for retreating, and saving Q for offense costs you the burst window. Watch for animation cancel opportunities into auto-attacks immediately after the ability lands, as that transition is where the bulk of his trade damage lives.
W appears to function as Billow's mid-combo damage tool or defensive layer, likely a short-range area strike or damage-mitigation buff that slots into the middle of his burst sequence. Don't open with W; it has shorter utility as an opener compared to Q's mobility value. Cooldown management here is critical: at S-tier play, your opponents are watching your W cooldown actively, so blowing it to poke rather than all-in is a major tell that lets them trade back freely.
Billow's ultimate is his kill-confirm and teamfight finisher, the ability you build your combo around, not the ability you throw in panic. At high rank, the biggest mistake is ulting too early in a trade when the opponent still has escape tools available; hold it until they have burned their dash or blink, then commit. In teamfights, look for opportunities to hit multiple targets with the ultimate's area rather than tunneling onto a single carry, as that's where Billow transitions from a skirmisher to a genuine fight-swinger.

Core Combos
Standard All-In
12RYour bread-and-butter kill combo for lane duels, open with Q to close distance and trigger the trade, weave auto-attacks between abilities to maximize passive stacks, and save R as the finisher once the opponent's escape is burned.
Flicker Ambush
12RUse Flicker to close an unexpected gap before the opponent can react, then chain the full combo immediately, best used in the mid-game jungle skirmishes where the enemy is slightly out of position.
Poke-to-Execute
12A safer partial combo for when you want to test the opponent's HP without fully committing, if they drop below 40% HP, transition into the full all-in with R to secure the kill.
Gameplan
Billow's first real spike is level 4, when his core abilities are available in combination and he can run a full trade rotation for the first time. The second, more dominant spike arrives when he completes his first major damage item. That is when his burst window goes from threatening to lethal. His peak window is between the first and second towers, where map geometry forces skirmishes and his short-range kit is not exposed. Late game, against full-build tanky compositions, stop committing into the front line and force fights on isolated targets instead.
Early Game
Levels 1–6- →Play aggressively at level 2 once your Q is available — most slayer opponents have not yet reached their own power spike and you can force an early HP lead.
- →Track the enemy jungler's first clear path and avoid overextending in river-adjacent bushes; Billow has limited escape tools and an early gank counter can erase your lane lead instantly.
- →Deny the opposing laner farm under tower by threatening every time they step up to last-hit — your threat range is enough to make them respect you even if you don't always commit.
Mid Game
Post Broken Spear- →Rotate to Dragon immediately after your first tower falls — your burst damage in skirmishes is at its peak and Dragon teamfights are where Billow earns his keep.
- →Look for solo picks on the enemy carry if they step into the river without their support nearby; one successful assassination mid-game often breaks the enemy draft's coherence.
- →Maintain lane pressure even while rotating by pushing the wave before leaving — Billow's wave clear should be fast enough that you lose minimal tower HP for each objective contest.
Late Game
Teamfight phase- →Identify the enemy's lowest-mobility damage dealer and make them your assassination target in every teamfight — do not frontline, do not tank; find your kill and commit.
- →Peel back toward your own carry if the enemy has a fed assassin; Billow's burst damage is a legitimate deterrent and positioning between your carry and the threat is sometimes more valuable than engaging.
- →In close late-game fights, hold your ultimate until after the enemy support or tank has used their displacement abilities — going in before they do guarantees you get locked down mid-combo.
Matchups
One rule governs Billow's draft position: never first-pick him into an unknown enemy slayer. Allain, Butterfly, Murad, and Florentino all make his life genuinely difficult. In those matchups you are fighting on cooldown disadvantage constantly, so play for jungle assistance rather than solo trading, and line up your jungle buff timers with your power spike windows to force fights only when ahead. In favorable drafts, lock Billow in after the enemy has committed their slayer pick. That way you can choose a support who locks opponents down. Baldum and Grakk in particular turn Billow from a strong pick into a near-unavoidable death sentence for whoever they target together.
Billow gets countered by
AllainAllain's sustained damage output and long-range poke chip Billow down before his burst window is even available, and Allain's dash gives him an escape route that makes Billow's engage unreliable.
ButterflyButterfly's evasion and rapid repositioning let her avoid Billow's committal engage and punish his cooldown downtime with sustained DPS from a safe angle.
MuradMurad's ultimate takes him out of Billow's targeting window at the exact moment Billow wants to all-in, making it nearly impossible to land the full combo when Murad plays around his ult cooldown.
FlorentinoFlorentino's multiple dashes and dueling tools let him match Billow's burst with his own aggression while having better mobility to dodge the all-in or reset back to safety.
Billow synergizes with
BaldumBaldum's hard displacement locks enemies in place long enough for Billow to execute his full combo without the target dashing away, one of the cleanest kill setups in the game.
GrakkGrakk's hook pulls isolated targets directly into Billow's melee range, transforming what would be a risky engage into a guaranteed burst opportunity.
AnnetteAnnette's crowd control and frontline pressure allow Billow to identify and collapse onto a single target while the enemy team is too disrupted to peel properly.
ArumArum's long-range snare gives Billow the entry point he needs on mobile targets who would otherwise dash out of his engage range mid-combo.
Pro Tips
- →Track your opponent's escape ability cooldown visually, the exact moment they burn their dash or blink on a non-committal poke is your window to go all-in; this is the single biggest skill expression gap between average and high-rank Billow.
- →Against heavy poke lanes, buy your first component item before backing rather than waiting for a full-item back, the extra HP and damage you get sooner is worth more than one efficient recall.
- →In teamfights, resist the instinct to target whoever is closest to you; take the extra half-second to identify the enemy's main damage dealer and path toward them through the skirmish rather than dumping your combo on a tank.
- →Use Flicker offensively rather than defensively in at least 70% of your games, Billow's disengage without Flicker is acceptable, but his engage without Flicker is predictable and easily respected by high-rank opponents.
Billow is the right pick for players who want to control a game from the slayer lane outward. He is punishing, snowball-oriented, and genuinely scary when ahead. He rewards the discipline to wait for the correct all-in window far more than he rewards mechanical complexity, so game-sense investment pays off faster here than on flashier heroes. The single most important habit to build on Billow is opponent cooldown tracking. The instant their dash is burned, you go in without hesitation. Players who internalize that will find S tier is not just a label on a tier list.
Billow — Frequently Asked Questions
Is Billow good in the current ROV patch?+
Yes. Billow is firmly S tier on the Thai server this patch, with a 50% win rate backed by a 26.7% pick rate and a 19.3% ban rate. Those ban numbers confirm that high-rank lobbies consider him a genuine threat worth removing from the game entirely, which is the clearest sign of a dominant meta pick.
What is the best build for Billow?+
Prioritize attack damage and armor penetration in your first two slots to maximize damage during his short combo sequence. Add survivability in your third slot so you are not dead immediately after going in. The exact recommended items shift with each patch, so cross-reference with current Thai-server build data for the latest optimal order.
How do you counter Billow?+
A mobile slayer who can dodge his engage or reset mid-trade is the cleanest answer. Butterfly and Murad are the best options in the current roster. At the team level, running hard-displacement supports like Grakk or Baldum against him (rather than alongside him) removes Billow's ability to safely reach his assassination targets in teamfights.
Is Billow hard to play / good for beginners?+
Billow sits at Medium difficulty. The basic combo is approachable, but the ceiling is high. Beginners can learn the core burst rotation quickly, and consistently reading cooldown windows, both yours and the enemy's, takes real game sense to develop. Players coming from other burst warriors will find the transition comfortable. Players new to the slayer role should expect a learning curve around trade timing.
