The short version

30-second read
  • Bring a weapon with range 7 or more. The portal sits seven tiles away, and the wiki recommends 8 so an enraged Vespula cannot reach you.
  • Leave the portal alone while she flies. Hitting it enrages her, and she then stings for up to 20 and stomps anyone underneath.
  • Fire spells hit the portal hardest. It takes 50% extra fire damage and has +60 magic defence against +110 to +140 ranged.
  • Each blossom heals a grub for 35. One player should do nothing but pick blossoms and top up the lowest grub.

Vespula OSRS: How the Room Works

Vespula is the giant wasp combat room in the Chambers of Xeric, and the room is over when her abyssal portal is destroyed. She has 200 hitpoints and flies for most of the fight, so only magic, ranged or a halberd can hurt her. Get her to 20% health and every hit has a chance to knock her to the ground for about 20 seconds. That window is when you kill the portal.

Everything else in the room supports that one goal. Four lux grubs sit around the room and Vespula stings them while she fights. If a grub's health runs out it hatches into a vespine soldier, and soldiers heal both her and the portal. One player keeping the grubs fed is what stops the room dragging on.

She is not aggressive when you walk in. She only starts firing once someone attacks her, so the team can take positions first.

The Vespula Portal

The abyssal portal is the real target. At maxed-player stats it has 250 hitpoints, 176 Defence and 176 Magic, and it takes 50% extra damage from fire spells. Its defence bonuses are +60 against magic and +140, +140 and +110 against light, standard and heavy ranged, so magic is the better style on it, with ranged as the fallback.

It sits seven tiles from the floor you can stand on. You need a weapon with a range of 7 or more to hit it at all, and the wiki recommends 8 so an enraged Vespula cannot reach you. Tumeken's shadow, the eldritch nightmare staff and longbows reach it on any attack setting. Other powered staves and crossbows need the long range setting, or you end up close enough to get hit.

The portal fights back in a small way. While it is being attacked, a faint green projectile drains 3 prayer points every 2 ticks from players in its range, and once your prayer is empty it deals 3 damage instead. Players on the Redemption method should not be hit by it.

Hitting the portal while Vespula is still flying enrages her. She flies back and forth in front of it, stinging anyone in melee range for 5 to 20 typeless damage and stomping anyone underneath her for 2 to 8 every tick, and she stays enraged until the portal stops taking hits. If the portal survives her grounded window, she takes off again and restores her health.

03

Lux Grubs, Blossoms and Vespine Soldiers

Four lux grubs spawn with Vespula, each with 125 hitpoints. She stings them while she fights, and a grub that hits 0 hatches into a vespine soldier. Soldiers attack with melee, poison starting at 15, and heal both Vespula and the portal for as long as they are alive.

The counter is medivaemia blossoms. Roots at the far end of the room produce them, and each blossom fed to a grub heals it for 35. It was 20 before the 29 November 2023 update, so a guide quoting a lower number is out of date. In a team, one player does nothing but pick blossoms and top up whichever grub is lowest.

If a soldier does hatch, kill it with melee once it drops to the ground. The wiki notes they explode after 20 seconds for moderate damage, so either way it is a short problem, and a new grub respawns after the soldier dies.

Best Gear for Vespula

Table 2Vespula weapons, in the wiki's order6 rows
WeaponWhy it is on the list
Tumeken's shadowReaches the portal on any setting, and magic is the portal's weak style.
Harmonised nightmare staffNeeds a tome of fire and Fire Surge, which also uses the 50% fire weakness. Only effective if you hit the portal every 4 ticks.
Sanguinesti staffSet it to long range. Only effective if you hit the portal every 4 ticks.
Twisted bowThe ranged option for both Vespula and the portal.
Bow of FaerdhinenOnly effective if you hit the portal every 4 ticks.
Dragon hunter crossbowSet it to long range so the portal is in reach and you stay out of its drain.

Vespula herself has +0 defence against stab, slash and crush, +70 against magic and +20, +60 and +60 against light, standard and heavy ranged. While she flies, melee does nothing unless you hold a halberd, which has been allowed since the 6 August 2025 update. Once she lands, any style can hit her, but your hits belong on the portal.

05

Inventory and Supplies

  • Antipoison or anti-venom. Her ranged attack can poison starting at 20, and soldiers poison starting at 15.
  • Prayer potions or a prayer enhance (+). While the portal is being attacked it drains 3 points every 2 ticks from anyone standing in its range.
  • Runes for fire spells if your staff can autocast them. Fire takes 50% extra on Vespula and on the portal.
  • Food for the sting and the stomp if you end up near her while she is enraged.
06

Vespula's Attacks and Max Hits

Table 3Vespula attacks (wiki values at maxed-player stats)4 rows
AttackWho it hitsDamage
RangedPlayers attacking her; she only retaliatesUp to 14, can poison starting at 20
StingAnyone in melee range while she is enraged and flying5 to 20 typeless
StompAnyone underneath her while she is enraged and flying2 to 8 every tick
Portal drainPlayers in the portal's range while it is being attacked3 prayer points every 2 ticks, or 3 damage with no prayer left

Her attack speed is 3 ticks and she takes up a 5x5 area. She regenerates 1 stat point every 10 ticks, ten times the normal rate, so Defence drains on her do not last. She is fully immune to poison and venom.

07

Where Vespula Fits in a Raid

Vespula is one of the combat rooms a Chambers of Xeric raid can roll, alongside Tekton, Vasa Nistirio, Vanguards and Muttadiles. Unlike Vasa, she waits for you to start the fight, so you can put the grub feeder at the roots and spread the damage dealers out before the first hit.

08

Fight Strategy: The Normal Method

  1. 1

    Pick one grub feeder before anyone attacks.

    Their job is blossoms, not damage.

  2. 2

    Everyone else hits Vespula with magic, ranged or a halberd.

    Leave the portal alone while she is flying, because hitting it enrages her.

  3. 3

    From 20% health she can land on any hit, and she is guaranteed to land if she reaches 1 hitpoint first.

  4. 4

    The moment she is grounded, everyone switches to the portal.

    You have about 20 seconds.

  5. 5

    If the portal survives, she flies, heals, and you start again from step 2.

    Kill any soldier that hatched before you go back to her.

09

Vespula Tiles: The Redemption Method

Faster teams and soloers use the Redemption method, which is what people mean by the Vespula tile. It needs 90+ Hitpoints. You stand on one specific tile two squares from Vespula, which is halberd range, on the same row or column as her. Make your attack, run straight back to that tile, and repeat until Redemption activates.

Each attack costs you 6 to 24 damage, and Redemption cancels it out. Stand on any other tile and the stinger jabs you instead. The wiki suggests quick prayers of Redemption plus Augury or Rigour, or Redemption on its own if you want more margin, with a prayer enhance (+) or an extra prayer potion to pay for it.

10

Drops and Points

When the portal dies the room always drops two Xeric's aid (+)(4), a revitalisation (+)(4), a prayer enhance (+)(4) and an overload (+)(4). The overload has been guaranteed since the 29 November 2023 update. The 31 January 2019 update also slowed the portal's regeneration and raised the points it gives per damage dealt.

11

Combat Achievements

The Vespula task is Redemption Enthusiast, an Elite Combat Achievement: destroy the abyssal portal without forcing Vespula to land. Despite the name, Redemption is not required. Every hit goes on the portal while she is still flying, so she stays enraged for the whole room. The wiki's approach uses Redemption at 90+ Hitpoints: hit the portal, let Redemption heal you, step out of her range to restore prayer and turn quick prayers back on, then go again. Solo, set raid scaling to 0, since scaling 1 doubles her health.

Ironman Notes

An ironman without a Tumeken's shadow still has options here. Fire spells get the 50% weakness on both Vespula and the portal, and a longbow reaches the portal on any attack setting, so an ironman has a magic and a ranged answer without raid uniques.

13

Common Mistakes and Death Causes

  • Hitting the portal while she is still flying. She enrages, stings for up to 20 and stomps anyone under her.
  • Leaving the grubs unfed. Every soldier that hatches heals her and the portal.
  • Bringing a weapon that cannot reach the portal. You need range 7 or more, and most staves and crossbows need long range.
  • Standing off her row or column on the Redemption method, which gets you jabbed by the stinger.
  • Slow switches when she lands. You get about 20 seconds before she flies again and heals.

FAQ

How do you kill the Vespula portal?

Get Vespula to 20% health so she lands, then switch everyone to the abyssal portal. It has 250 hitpoints and takes 50% extra damage from fire spells. You have about 20 seconds before she takes off again and restores her health.

Is there a safe spot at Vespula?

Not a true one. The Redemption method uses a tile two squares from Vespula on her row or column. On that tile each attack costs 6 to 24 damage, which Redemption cancels. Any other tile near her gets you hit by the stinger.

Can you melee Vespula?

While she is flying, only a halberd works, and only since the August 2025 update. Once she lands at 20% any style can hit her, but that window should go on the portal.

How much HP does Vespula have?

200 hitpoints at maxed-player stats. The abyssal portal has 250, and each lux grub has 125.

What do the grubs do at Vespula?

Vespula stings the four lux grubs. A grub at 0 hitpoints hatches into a vespine soldier, which heals her and the portal while it lives. Feed them medivaemia blossoms, 35 hitpoints each, to stop that.

What does Vespula drop?

Two Xeric's aid (+)(4), a revitalisation (+)(4), a prayer enhance (+)(4) and a guaranteed overload (+)(4), dropped when the portal dies.

15 · Bottom line

Bottom Line

Vespula is a portal room with a wasp in front of it. Feed the grubs, drop her to 20%, and put every hit on the portal while she is on the ground. Once that loop is clean the room stops costing supplies.

If you want Chambers of Xeric completions without learning every room yourself, our CoX raid service is played by hand. The bosses list has the rest of the index.
