OSRS Demonic Gorillas Strategy Guide for Maximum Profit

Demonic Gorillas in Old School RuneScape (OSRS) are a challenging yet rewarding Slayer monster found in the Crash Site Cavern after completing Monkey Madness II. Known for their valuable drops like zenyte shards and ballista components, they’re a popular choice for players seeking profit and experience. This comprehensive guide covers everything you need to know to efficiently kill Demonic Gorillas, including mechanics, gear setups, strategies, and tips to optimize your trips.
Demonic Gorillas are level 275 monsters that require at least two combat styles to defeat due to their unique mechanics. They use protection prayers and switch combat styles, making them a complex foe for unprepared players.
Protection Prayer Switching
Demonic Gorillas switch between Protect from Melee, Protect from Missiles, and Protect from Magic after taking 50 or more damage from a single combat style. This forces you to alternate between melee and ranged attacks (magic is less effective due to their high magical defense). For example, if you deal 50 damage with melee, the gorilla will activate Protect from Melee, requiring you to switch to ranged.
Attack Style Switching
The gorillas use all three combat styles—melee, ranged, and magic—each hitting up to 30 damage. They switch their attack style after three consecutive misses (hits that deal zero damage), regardless of whether your protection prayer blocked them. Recognizing their attack animations is crucial:
- Melee: The gorilla swipes its claws downward.
- Ranged: The gorilla grabs a boulder and throws it.
- Magic: The gorilla rears up and emits a green orb from its mouth.
Boulder Toss Special Attack
When using ranged or magic, gorillas may perform a boulder toss, indicated by a shadow above your position. If you don’t move at least one tile away, you’ll take damage equal to 33% of your current health. This attack doesn’t count toward their three-miss switch mechanic.
Prerequisites and Requirements
Before heading to the Crash Site Cavern, ensure you’re prepared with the necessary quests, stats, and gear.
Quest and Skill Requirements
To access Demonic Gorillas, you must complete the following:
- Monkey Madness II: Unlocks the Crash Site Cavern.
- Recommended Skills: 80+ Attack, Strength, Defence, Ranged, and 70+ Prayer for overhead prayers.
- Optional Quests: Recipe for Disaster (for Barrows gloves), Dragon Slayer II (Ava’s assembler), and Shadow of the Storm (Arclight access).
Location and Access
Demonic Gorillas reside in the Crash Site Cavern, northwest of the Grand Tree in the Tree Gnome Stronghold. Use a royal seed pod for quick access. The cavern has both multi-combat and single-combat areas—stick to the single-combat area to avoid being overwhelmed.
Optimal Gear and Inventory Setup
Your gear and inventory are critical for maximizing kills per hour and minimizing supply costs. Below is a breakdown of recommended setups.
Best-in-Slot Gear
Since you’ll switch between melee and ranged, prioritize gear that balances damage output with prayer bonuses. Here’s a recommended setup:
Slot | Melee Item | Ranged Item |
---|---|---|
Head | Slayer Helmet (i) (on task) | Slayer Helmet (i) or Armadyl Helmet |
Cape | Infernal Cape | Ava’s Assembler |
Neck | Amulet of Torture | Necklace of Anguish |
Body | Bandos Chestplate | Armadyl Chestplate |
Legs | Bandos Tassets | Armadyl Chainskirt |
Weapon | Arclight or Abyssal Bludgeon | Toxic Blowpipe or Twisted Bow |
Shield | Avernic Defender | N/A |
Gloves | Barrows Gloves | Barrows Gloves |
Boots | Primordial Boots | Pegasian Boots |
Ring | Berserker Ring (i) | Archers Ring (i) |
Budget Alternatives: Use a Rune Crossbow with broad bolts instead of a Blowpipe, or a Dragon Scimitar if Arclight isn’t available.
Inventory Setup
Your inventory should support extended trips while allowing quick switches. A typical setup includes:
- 1 Super Combat Potion: Boosts melee stats.
- 1 Ranging Potion: Boosts ranged accuracy.
- 4-6 Prayer Potions: Restores prayer points for protection prayers.
- 1 Saradomin Godsword (optional): For special attack healing.
- Rune Pouch: With runes for High Alchemy or Teleport to House.
- 10-12 Sharks or Better: For healing.
- Switch Items: Necklace, weapon, and armor switches (e.g., Torture/Anguish, Blowpipe/Arclight).
Combat Strategy for Demonic Gorillas
Mastering Demonic Gorillas requires precise prayer and gear switching while maintaining high damage output. Here’s a step-by-step strategy.
Preparation and Initial Engagement
Enter the single-combat area of the Crash Site Cavern to avoid multiple gorillas. Turn on Protect from Magic or Ranged (default guesses, as melee is less common initially). Approach a gorilla and observe its first attack to adjust your prayer:
- Magic Attack: Keep Protect from Magic.
- Ranged Attack: Switch to Protect from Missiles.
- Melee Attack: Switch to Protect from Melee and step away to avoid consecutive hits.
Switching Combat Styles
Monitor the gorilla’s protection prayer (visible overhead). If it’s using Protect from Melee, attack with ranged; if Protect from Missiles, use melee. After dealing 50 damage with one style, switch immediately to avoid wasting hits. For example:
- Start with Arclight (melee) while the gorilla uses Protect from Missiles.
- After 50 damage, it switches to Protect from Melee—equip Blowpipe and attack with ranged.
- Repeat, alternating styles based on its prayer.
Managing Boulder Toss
Watch for the boulder toss during ranged or magic phases. As soon as you see the shadow, move one tile to avoid taking heavy damage. Staying mobile reduces the risk of being caught off-guard.
Prayer Flicking and Efficiency
Experienced players can flick prayers to conserve points, activating the correct protection prayer just as the gorilla attacks. Use the RuneLite plugin for Demonic Gorillas, which tracks attack counts and predicts switches, making prayer flicking easier. Avoid over-switching gear—limit switches to weapons and necklaces (e.g., Torture to Anguish) to maintain DPS without overwhelming yourself.
Tips for Maximizing Profit and Efficiency
Demonic Gorillas are a lucrative money-maker, with average kills worth around 90,000 coins (including zenyte shards) or 21,000 without shards. Here are tips to boost your success.
Slayer Task Advantage
Kill Demonic Gorillas on a black demon or monkey Slayer task for bonus experience and damage with a Slayer Helmet (i). This increases kills per hour, especially with Arclight, which is highly effective against demons.
Healing and Sustainment
Use the Saradomin Godsword special attack to heal and restore prayer, extending trips. Alternatively, Guthan’s equipment can heal but reduces DPS due to extra switches. Gorillas drop sharks and brews, so rely on these to conserve inventory space.
Multi-Combat vs. Single-Combat
Stick to the single-combat area unless duo-ing with a partner using full Dharok’s at 1 HP for high damage output (advanced strategy). Multi-combat is risky due to multiple gorillas attacking simultaneously.
Loot Management
High Alchemy runes help alch low-value drops like rune platelegs to save inventory space. Prioritize picking up zenyte shards, ballista springs, and high-value seeds. Expect 50-60 kills per hour with decent gear, yielding 700,000 to 3,000,000 coins hourly, depending on shard luck.
Demonic Gorillas are a fantastic way to combine profit, combat experience, and Slayer progress in OSRS. By mastering their mechanics, optimizing your gear, and refining your switching technique, you’ll turn these challenging foes into a consistent money-maker. Equip your Arclight, load up your Blowpipe, and head to the Crash Site Cavern to start farming those zenyte shards!
