Most post-plant advice stops at ‘throw a molly on the spike.’ It doesn’t explain why that works so reliably, so players default to whatever ability they have up instead of the one that actually kills. The mechanic that makes mollies so strong is buried in a single line on Riot’s own wiki: a defuser is rooted in place the moment they start defusing. They can turn their camera to check angles, but they cannot walk out of a damage zone. Combine that with the official damage numbers for Incendiary, Snake Bite, and Nanoswarm, and denial turns into a solvable equation — some mollies are fast enough to kill outright before the defuse timer even matters, others aren’t, and most players use the wrong one for the situation. This guide breaks down the exact math and gives you a decision tree for which molly to reach for and when. Verified against Patch 13.00.
Quick Start: The Post-Plant Denial Checklist
- Confirm your team is off attacker mindset — you’re defending the spike now, not hunting kills
- Land your molly on the exact plant tile, not near it — a defuser can survive at the edge of Incendiary or Snake Bite’s 4.5-meter radius
- If you have Killjoy, favor Nanoswarm over Turret for post-plant — it triggers through walls with no line of sight needed
- Match your molly to the clock: use Incendiary or Nanoswarm when you need a kill fast, Snake Bite when you’re stalling for the 45-second timer
- Hold crossfires, not stacked corners — two players on linear angles force a trade if the defuser survives your molly
- Don’t push past the spike unless it wins map control or denies a specific retake lane
- If your molly whiffs, fall back on the 3.5-second checkpoint math from our full spike-timing breakdown — it covers the 2.4-second open-vs-cover plant rule this guide doesn’t repeat
Why a Well-Placed Molly Is (Almost) Unbeatable
Here’s the part most guides skip. Riot’s own wiki states that once a defuser commits to the defuse, they’re rooted — they can cancel and back off, but they can’t reposition while defusing is active. In a lot of shooters, staying still under fire is a choice. In Valorant, during a defuse, it’s the only option. That single constraint is what makes post-plant utility so much stronger than pre-plant utility: you’re not trying to flush someone out of cover, you’re throwing damage at a target that has already agreed not to move.
That changes what a molly needs to do. It doesn’t need to force a decision — it needs to out-damage the defuser’s HP pool before they choose to cancel. And because the checkpoint system saves progress at the 3.5-second mark, a defuser who takes damage early and lives will often push through rather than cancel, since cancelling before 3.5 seconds throws away all their progress. That’s the exact moment a molly should be landing — it punishes the players most likely to gamble on finishing the defuse.
The Molly Math: Which Ability Actually Kills a Defuser
Every Valorant player starts a round with 100 HP, 125 with Light Shields, or 150 with Heavy Shields. Here’s how the three main post-plant mollies stack up against those numbers, using Riot’s official per-ability stats.
| Ability | Official damage | Time to kill (100 / 125 / 150 HP) | Risk to you |
|---|---|---|---|
| Brimstone Incendiary | 60 damage/second, 8s zone | ~1.7s / ~2.1s / ~2.5s | Must land it precisely — no remote retrigger once thrown |
| Killjoy Nanoswarm | 180 total damage over a 5s window (buffed from 4s in Patch 13.00) | Lethal to any HP pool within the full 5s window if the defuser stays in it | Lowest — activates through walls, zero line of sight required |
| Viper Snake Bite | 76–79 total damage over 6.5s, plus 2s Vulnerable (doubles incoming damage) | Doesn’t solo-kill any pool | Low if thrown from Pit or an off-angle |
Incendiary is the outlier. At its stated 60 damage per second, it kills a fully-shielded defuser in about two and a half seconds — inside the 3.5-second checkpoint window, before progress even saves. That’s the mechanism behind the ‘Brimstone is the best post-plant agent’ reputation you’ll see repeated across community guides: it’s not opinion, it’s the only ability on this list that reliably wins the damage race outright.
Nanoswarm is close behind, and in some ways safer to use even though its total damage is spread more gradually. Because it triggers with no line-of-sight requirement, Killjoy can hold an angle across the map, watch the spike beep, and detonate the moment someone starts a defuse — no risk of getting caught mid-throw. I’ve watched ranked lobbies lose winnable post-plants because the Killjoy peeked to confirm a lineup landed instead of just trusting the remote trigger; that peek is the only real risk in this whole equation, and it’s avoidable.
Snake Bite is the honest exception. It won’t kill anyone on its own inside its 6.5-second window — the math doesn’t support that claim, and a guide that told you otherwise would be lying to you. What it does is force a choice: sit in a shrinking HP bar and hope your team doesn’t follow up during the Vulnerable window, or cancel and lose the checkpoint. Pair it with literally any teammate holding an angle and the Vulnerable debuff turns a normal headshot into a guaranteed kill even through Light Shields.
Landing It Without Memorizing a Lineup
You don’t need to memorize a fixed lineup for every site on every map. Ping the spike on your minimap, aim straight up, and walk forward while watching the minimap’s sound-radius circle — release the throw the moment that circle lines up with your ping and it lands close enough to matter. It’s not a laser-precise substitute for a practiced lineup, but it’s fast to learn and works from almost any position.
The one hard limit: throw position and target need to be at the same elevation. Try this from a lower or higher level than the site — throwing from A Main up to A Haven on Ascent is the classic example — and the minimap trick breaks because the arc doesn’t behave the same way vertically. If you’re playing a level change onto or off of the site, learn the specific lineup for that spot instead of relying on the minimap method.
Decision Tree: Which Molly, and When
| Situation | Use | Why |
|---|---|---|
| You need a kill before the 3.5s checkpoint saves | Incendiary | Only ability that outpaces the checkpoint on its own |
| You don’t have LOS on the spike, or you’re worried about getting picked mid-throw | Nanoswarm | No line-of-sight requirement to trigger |
| You’re just trying to survive to the 45-second detonation, not force a fight | Snake Bite | Slowest damage of the three, but the Vulnerable debuff stacks with any teammate’s follow-up shot — no full commitment needed |
| Defuser already passed the 3.5s checkpoint | Any — but pair it with a teammate’s crossfire | Killing them still denies the back-half defuse; a lone molly that doesn’t kill just delays a relay defuse from a second player |
That last row matters more than most players realize. Once the checkpoint is saved, a molly that doesn’t kill only buys time — it doesn’t reset anything. If you don’t have the damage to finish the job, your molly is a stall tool, not a denial tool, and you need a teammate’s crosshair on the entry angle to close it out.
How Much Denial Do You Actually Need?
A kill isn’t always the goal. The spike detonates 45 seconds after plant regardless of what happens on site, and a defender must have started their defuse by the 38-second mark to have any chance of finishing — the round is over the instant that window closes, whether or not anyone died. That means the real question isn’t ‘can my molly kill this defuser,’ it’s ‘can I deny them for the time remaining on the clock.’
Planted early with 40+ seconds still on the timer? A kill matters, because a coordinated retake has time to send a second and third defuser after the first one dies. Planted late, with 15 seconds or less before the 38-second cutoff arrives? A single Snake Bite that forces a cancel is often enough — there isn’t time left for a relay defuse to matter even if the first defuser survives. Read the clock before you decide which molly is worth spending.
Positioning and Crossfires When You Don’t Have a Molly
Duelists and Initiators don’t get a post-plant molly, and most rounds you won’t have a Controller or Killjoy alive anyway. In that case, the plant position you chose earlier in the round decides your options. A spike planted in cover means defenders can use that same cover to defuse from — your hold needs to cover the approach to that cover, not the spike tile itself. A spike planted in the open forces every entry angle to expose the defuser, which is what our spike-timing guide covers in full detail with the exact 2.4-second exposure cost.
Either way, hold crossfires: two teammates on linear, non-stacked angles that force a trade if either one gets picked.
Pushing past the site only makes sense for two reasons — denying a specific retake lane you know is coming, or turning a 1v2 into a 1v1 with a pick. Pushing to ‘clean up’ or because you’re bored costs rounds that were already won.
Post-Plant by Player Type
| Player type | Priority |
|---|---|
| New player | Learn the 3 numbers that matter — 45s detonation, 7s defuse, 3.5s checkpoint — before worrying about lineups. Hold one angle and don’t peek. |
| Casual player | Memorize one Incendiary or Nanoswarm lineup per map on your main agent. One reliable lineup beats five you half-remember. |
| Hardcore / optimiser | Build the full TTK table above into muscle memory per HP pool, and track whether the enemy is running Light or Heavy Shield off their buy to pick the right molly pre-emptively. |
| Completionist | Learn Snake Bite, Incendiary, and Nanoswarm lineups on every map so you’re never stuck holding an off-angle with no post-plant tool up. |
Common Post-Plant Mistakes
- Throwing the molly near the spike instead of on it. A few feet outside the 4.5-meter radius and the defuser takes zero damage
- Peeking to confirm a Nanoswarm landed. It doesn’t need line of sight — peeking just trades your remote-trigger safety for a risky duel
- Using Snake Bite when you needed a kill. It’s a stall tool. If the round needs a body, it’s the wrong pick.
- Stacking one corner instead of crossfiring. One angle is one angle to clear, no matter how many bodies are behind it
FAQ
Does a molly always kill a defuser?
No — only Incendiary reliably does, and only if it lands directly on the plant tile. Nanoswarm can too if the defuser stays in it for the full 5-second window, but a defuser who cancels early survives. Snake Bite doesn’t have the damage output to kill alone as of Patch 13.00.
Is Nanoswarm better than Incendiary for post-plant?
Depends what you’re optimizing for. Incendiary kills faster in a straight damage race. Nanoswarm is safer to use because it doesn’t require line of sight to trigger, so pick Incendiary when you need the fastest possible kill and Nanoswarm when your angle on the spike is bad or you’re worried about being picked off mid-throw.
Why did Killjoy’s Nanoswarm get a duration buff in Patch 13.00?
Riot bumped it from 4 to 5 seconds alongside Turret and Alarmbot buffs, part of a broader Sentinel/Initiator buff pass that patch. The extra second matters specifically for post-plant, since it’s more time for total damage to catch up to a Heavy Shield HP pool.
Do I need to buy Shields just to survive post-plant mollies as a defender?
If you’re on the receiving end, yes — a Heavy Shield buys you roughly an extra second against Incendiary and meaningfully more time against Snake Bite’s slower tick damage, which can be the difference between finishing a defuse and getting cancelled. See our economy guide for when a full buy is actually worth it versus saving.
Key Takeaways
The reason mollies work in post-plant isn’t mysterious once you know the rule: defusers can’t move. Once you accept that, the only question left is which ability’s damage output beats the HP pool in front of it fastest. Incendiary wins that race outright. Nanoswarm wins it safely. Snake Bite doesn’t win it alone, and pretending otherwise gets people killed holding a molly that was never going to finish the job. Learn the numbers once and you stop guessing which ability to throw — you calculate it.
