The Stone Guardian
A solo boss in a private chamber under Varrock. Learn its specials, collect its loot and forge Stonebreaker from its core.
The Stone Guardian is a solo boss in a private chamber below Varrock. Bring your own gear, food and prayer potions. Dying there is safe, and its core forges Stonebreaker.
Getting in
Pull the Guardian lever in the Varrock sewers (90, 3301) and choose to enter. Mason stands beside it. There is no combat level requirement, but you need the current game client, and you cannot enter while in combat, poisoned or held by another event. Up to eight chambers run at once.
Inside you can fight, eat, drink, pray and switch gear, but teleports and most commands are blocked. Leave by the exit lever on the side wall, even during combat, or with ::guardian leave. Logging out, or a fight that runs past 15 minutes, also ends the attempt.
The fight
The Guardian fights in a loop: an exchange of blows, a special, then a rest.
| Phase | What it does | What you do |
|---|---|---|
| Exchange (about 16 ticks) | Opens with Void Strike from range, then fights in melee | Protect from Magic while it casts, Paralyze Monster in melee |
| Shatter (6 ticks) | Amber runes gather and a 3×3 area around you is marked | Walk out of the marked area |
| Ward (8 ticks) | It channels blue light and marks a 3×3 area a few steps away | Stand inside it for two ticks in a row |
| Rest (8 ticks) | Does not hit back | Attack or heal |
Shatter and Ward alternate, starting with Shatter, and once you are in melee a special waits until you have both had three rounds. A missed special deals 30 damage that no prayer stops. Crossing the Ward is not enough: you must still be inside on the second tick.
- The mace hits up to 54. Paralyze Monster (37 Prayer) stops it completely.
- Void Strike hits up to 12, and each hit drains a tenth of your current Prayer, rounded up. Protect from Magic (43 Prayer) blocks the damage and the drain.
Loot
Every kill gives 10,000 coins, 
Big Bones and one main reward: food, a potion, runes, arrows, runite bars or Rune equipment. Separate rolls can add a 
Guardian core, 
Midas gloves, a 
Guardian archway blueprint or a 
Runed guardian stone. Everything is unnoted; see the drop table.
The loot lands where the Guardian fell, and only you can take it. If you stay, the Guardian returns 60 seconds after its defeat. Loot you leave behind waits for you: talk to Mason and choose Claim my rewards, or use ::guardian claim. It goes to your inventory, or your bank if your inventory is full, and is never added on its own. ::boss shows the fastest solo kill and your personal best.
The blueprint and runed stone are for the Guardian archway, a level 99 Construction masterwork. You can study the blueprint before reaching 99 and save the stones for later. See Construction and the home islands.
Forging Stonebreaker
Carry an unnoted Guardian core, an unworn 
Rune Mace and 50,000 coins to Mason and choose Forge Stonebreaker. 
Stonebreaker needs 40 Attack.
While you wield it, your melee accuracy and max hit are 50% higher against the Stone Guardian and these giants: Giant, Moss Giant, Ice Giant, Fire Giant, Void Giant, Elder Moss Giant, Elder Fire Giant and Bone giant. Slayer level requirements still apply. Vharok's chain turns it into Oathbreaker: see Vharok and the Demon King.
