The short version

30-second read
  • Crystals are immune to ranged. They take a third damage from magic and have -5 stab defence, so bring a stab switch.
  • Let the lowest-Hitpoints player start the fight. The special scales with the current Hitpoints of players beside him, and solo it hits your Hitpoints minus 5.
  • Wall players run in to share the hit. Damage is split between everyone beside him, so standing still leaves the stunned players to take it all.
  • Range Vasa himself and never cast. His magic defence is +400, while crush sits at +40 and heavy ranged at +30.

Vasa OSRS: How the Room Works

Vasa Nistirio is the rock-and-crystal combat room in the Chambers of Xeric. He has 300 hitpoints, and the fight runs in a loop: he teleports the team, throws boulders, then walks to one of the four glowing crystals in the room's corners to heal. Break that crystal before he finishes siphoning it and the heal is wasted. Let him finish and he gets the health back.

He starts as a pile of rocks. Walking up to him starts the fight, a purple flame closes the entrance and burns anyone who passes through it, and his first move is the teleport special.

Vasa Crystals: How They Work

After each teleport Vasa lights one of the four crystals in the corners and walks to it. While he siphons it he cannot be damaged, so the whole team turns on the crystal. Since the 29 November 2023 update he only heals if he finishes the siphon. Break the crystal in time and he gets nothing.

A glowing crystal has 120 hitpoints, 100 Defence and 100 Magic at maxed-player stats. Its defence bonuses are -5 stab, +180 slash, +180 crush and +0 magic. It is immune to ranged, the ranged thrall included, and takes one third damage from magic. In practice that means a stab weapon.

There is a timer. When Vasa first reaches a glowing crystal, a 40 second timer (66 or 67 ticks) starts, and it only counts down while a crystal is active. At zero he leaves the crystal and walks back to the middle for another teleport. The next crystal he picks is always a different one, unless he has just used the special.

03

The Teleport Special

The teleport grabs everyone in the arena, plus anyone outside standing next to the flame. Solo, you land next to him. In a team, roughly half land next to him and the rest by the walls. Players next to him are stunned and cannot turn prayers on while he charges, and he cannot be attacked during the charge.

Then projectiles fall from him and explode on everyone beside him. The damage is based on the combined current Hitpoints of the players teleported next to him, and it is split between everyone standing next to him when it lands. Solo, it works out to your current Hitpoints minus 5, so 94 Hitpoints takes 89.

So in a team: players sent to the walls run in with Protect from Magic on, which splits the hit more ways while they take none of it themselves. The wiki also suggests the lowest-Hitpoints player starts the fight next to him. Solo, your options are to take the hit, start the special on low Hitpoints, or have Vengeance up so it recoils, though recoil damage gives no points.

Vasa's Attacks and Max Hits

Table 2Vasa Nistirio attacks3 rows
AttackWho it hitsPrayer
Teleport specialEveryone teleported next to him, split between players beside himProtect from Magic for anyone not stunned
BouldersPlayers within 8 tiles but not under him, 3x3 areaProtect from Missiles cuts accuracy and damage
StompAnyone directly under him, up to 8 every tickNo prayer answer. Do not stand there.

His attack speed is 3 ticks and his max hit is listed as varies, because the special scales with the team's Hitpoints. He is immune to poison and venom, and he is not undead, so a salve amulet does nothing.

05

Best Gear for Vasa

Vasa's defence bonuses are +170 stab, +190 slash, +40 crush, +400 magic and +40, +40 and +30 against light, standard and heavy ranged. Crush is his weakest melee style and heavy ranged is close behind, but the wiki still recommends ranged on Vasa himself because it keeps the damage you take down. Magic is wasted into +400. The November 2023 update also cut his ranged defence by 20 so the toxic blowpipe lands more consistently.

Inventory and Supplies

  • Prayer potions for two overheads: Protect from Magic for the special, Protect from Missiles for the boulders.
  • A stab switch for the crystals if your main weapon is ranged.
  • Overloads before entering, which the wiki's team notes recommend.
  • Vengeance runes if you are on the Lunar spellbook and soloing.
  • Food to cover the special if you take it solo without Vengeance.

Where Vasa Fits in a Raid

Vasa is one of the combat rooms a Chambers of Xeric raid can roll, alongside Tekton, Vespula, Vanguards and Muttadiles. He is aggressive, unlike Vespula, so agree who stands where before anyone walks up to the rocks.

Fight Strategy: Crystals and the Special

  1. 1

    The lowest-Hitpoints player starts the fight next to him.

    The teleport comes as soon as the fight starts.

  2. 2

    Anyone sent to the walls runs in with Protect from Magic to share the hit.

  3. 3

    Switch to Protect from Missiles after the magic hit lands.

    Boulders come next.

  4. 4

    When he walks to a lit crystal, everyone switches to stab and breaks it before the siphon finishes.

  5. 5

    Hit Vasa between crystals with ranged, and stay out from under him.

09

Drops: Does Vasa Drop an Overload?

Yes. Since the 29 November 2023 update Vasa always drops an overload (+)(4). The full guaranteed drop is one overload (+)(4), two Xeric's aid (+)(4), two twisted (+)(4) and five endarkened juice.

Combat Achievements

The Vasa task is Stop Drop and Roll, a Master Combat Achievement: kill Vasa Nistirio before he performs his teleport attack for the second time. The fight opens with the first teleport, so you get one loop. Land dragon warhammer or Bandos godsword specials early, hit him with your strongest ranged weapon (twisted bow, Bow of Faerdhinen with crystal armour, or a toxic blowpipe with dragon darts), and break each lit crystal fast with stab, because a crystal left alone too long sends him back to the middle to teleport. Vengeance at high Hitpoints on the first teleport throws a big chunk of damage back at him. Solo, set raid scaling to 0, since scaling 1 doubles his health.

Ironman Notes

Crystals ignore ranged, so an ironman on a ranged setup needs a stab switch. The Ghrazi rapier and inquisitor's mace top the wiki's crystal list, but both are hard to get on an ironman. Further down the same list are the Zamorakian hasta, the dragon hunter lance on its stab style and the dragon sword on stab, and any of them does real damage into a -5 stab defence.

Common Mistakes and Death Causes

  • Hitting crystals with ranged. They are immune to it.
  • Wall players standing still during the special, which leaves the stunned players to take the whole hit.
  • Keeping Protect from Magic up for the boulders, which are ranged.
  • Standing under Vasa and eating up to 8 every tick.
  • Casting on Vasa himself into +400 magic defence.

Bottom Line

Vasa is a crystal race with a big hit at the start of every loop. Share the teleport with Protect from Magic, stab every lit crystal before the siphon ends, and he never heals.
