Demonic Gorillas Guide

Bosses guide · Updated September 2025

Demonic Gorillas are the zenyte-farming bosses at the Crash Site Cavern - prayer-switching enemies that punish lazy prayer by adapting to whatever you protect against. The teleport lands at 2026, 5610 inside the cavern.

They are the zenyte jeweller's quarry: shards and jewellery come only from these gorillas, which keeps them permanently valuable.

The prayer-switching mechanic

Each gorilla prays against your attack style - pray against theirs and it switches styles to counter. The fight is a constant read: when your hits start splashing, change your own style, and when its prayer changes, adapt again.

They also drop boulders - a falling-rock AoE that punishes standing still - so repositioning is part of the rhythm.

Fighting them efficiently

The clean approach is tribrid or dual-style: switch between melee and ranged so the gorilla wastes a prayer on whichever you are not using. Black demonic gorillas are the tanky variant; the regular ones die faster.

  • Bring two attack styles - the prayer adaptation makes single-style slow.
  • Move when boulders drop - the falling rocks hit hard.
  • Their own prayer flicking is readable - watch the protect icon.

The drops

Zenyte shards, zenyte jewellery (amulet, ring, necklace, bracelet), ballista components, and light/heavy frame pieces for the gorilla warfare gear - plus the usual supply rolls. Every tradeable drop is GE-linked below.

The zenyte economy

Zenyte shards are the valuable drop - they upgrade onyx jewellery into the zenyte tier: the tormented bracelet, anguish necklace, suffering ring, and ornament amulet that are BiS for magic, ranged, tanking, and all-around use. On this server the shards trade on the GE like any other material.

The jewellery drops directly too - farming gorillas pays out in shards or finished pieces depending on the roll, so every kill is a roll on the same economy either way.

Common mistakes

  • Single-style attacking - the prayer adaptation stalls the fight.
  • Standing under the boulders - the falling rocks are the main danger.
  • Forgetting antipoison - some variants venom on contact.

Gear that handles the swaps

The gorillas reward mechanical skill more than raw stats: a player who reads the prayer swaps kills them twice as fast as one who brute-forces a single style. Treat every kill as practice for the raids, where the same adaptation check appears on a bigger stage.

  • Abyssal whip plus a rune crossbow covers both style rotations.
  • Karil's or Armadyl for the ranged phase, torso and tassets for melee.
  • Antipoison - the jungle is unfriendly.
  • Prayer potions; you will be flicking constantly.

The ballista components

Beyond zenyte, the gorillas drop heavy and light ballista frames plus the ballista limbs and spring - the full light ballista assembly for ranged spec builds. It is the secondary market that keeps gorilla farming profitable between zenyte rolls.

The monkey tail is the third notable drop - used in stringing the ballista, and worth picking up rather than leaving on the ground.
