Strategy

1. 1

   Range both, pray Missiles

   A ranged setup (blowpipe) handles both guardians cleanly — keep Protect from Missiles up and dodge the ground specials while you damage them.

2. 2

   Get a gargoyle task

   You can only fight them on a gargoyle (or Guardians) task, and your first roof entry needs a brittle key from gargoyles.

Key mechanics

What can kill you at Grotesque Guardians, and what to do about it. For the full breakdown, see the OSRS Wiki link below.

• Dawn's healing spheres

  Dawn releases energy spheres that heal her ~90 each if they reach her — destroy them, and damage both guardians evenly so they die close together (the survivor can revive the other).

• Rockfall & lightning

  The arena rains rocks (which can stun) and unleashes lightning on marked tiles — step out of the telegraphed areas.

• Prayer-disabling orb

  Watch for the orb that switches off your prayers on hit — flick them straight back on.

• Dusk's flame prison

  In the final phase Dusk flies, rains rocks, and traps you in a prison of flames that damages you — keep moving under Protect from Missiles and burst it down.

These figures are an independent-roll estimate: they treat every kill as a separate roll at the listed rate ( 1 − (1 − p)^KC). Real drops can involve guaranteed rolls, point/invocation scaling or completion rewards, so the true odds may differ. A probability is never a guarantee — even far above 90%, the drop is never owed to you. Drops without a fixed 1/Nrate show “—”.
