OSRS Cave Slime Slayer Task Guide: Everything You Need to Know

Did you just get assigned cave slimes as your Slayer task in Old School RuneScape (OSRS)? If so, you're in luck! Cave slimes are among the easiest Slayer creatures you’ll encounter, but they do have a few unique challenges you’ll want to prepare for. This detailed guide will cover everything you need to know — from gear and inventory setups to locations, strategy tips, OSRS Gold and loot information — so you can crush this task quickly and efficiently.

Cave Slime Requirements

Before you can be assigned cave slimes, you must have at least 17 Slayer. This low requirement means that cave slimes are usually assigned early in your Slayer journey. They are most commonly assigned by lower-level Slayer Masters such as:

Turael (Burthorpe)

Spria (Draynor Village)

Mazchna (Canifis)

Because of this, you’ll likely encounter cave slimes when you're still building up your combat stats and Slayer points.

Cave Slime Stats and Combat Information

Here’s what you need to know about cave slime stats:

Combat level: 23

Max hit: 2

Aggressive: No

Weaknesses: All forms of combat (Melee, Ranged, Magic)

Special hazard: Poison (starts at 3 damage)

Cave slimes have no defensive bonuses, so any attack style works just fine. That said, melee is often the fastest choice simply due to its higher base damage and attack speed at low levels.

 Important: Cave slimes poison you almost instantly after starting combat. The poison ticks for 3 damage initially, making it one of the bigger dangers of this otherwise simple task. Always bring an anti-poison or super anti-poison potion!

Recommended Gear and Inventory Setup

You don't need to break out your best gear for cave slimes — they’re weak and barely hit back. Just use whatever decent combat equipment you have for your preferred style. Here's a quick checklist to make sure you’re fully prepared:

Gear

Melee: Best strength gear you have (Iron/Steel/Rune Scimitar, etc.)

Ranged: Best bow or crossbow + basic armor (e.g., Leather, Snakeskin)

Magic: Staff of fire/air and basic spells (Wind Strike, Fire Strike)

Inventory Essentials

Anti-poison or Super anti-poison potions (MUST-HAVE)

Food: Lobsters, trout, or better, depending on your HP level

Light source: Bullseye lantern highly recommended (candles can explode!)

Tinderbox: Only needed if you’re using a relightable light source

Teleportation method: Lumbridge teleport, Ring of dueling, or Amulet of glory

Rope: Only required if it's your first time entering Lumbridge Swamp Caves

Spiny helmet: Optional, but useful if you risk running into wall beasts

Pro Tip:

Bring a little extra food if you’re lower combat level — the combination of low max HP and poison ticks can be dangerous if you’re not paying attention.

Cave Slime Loot Table

Let’s be honest: Cave slimes are not profitable. You aren’t killing them for money — you’re killing them for quick Slayer experience.

Here’s what they can drop:

Item Notes

Swamp tar Guaranteed drop; useful for questing and Herblore

Iron and bronze weapons Low value; not worth picking up

Iron boots Collection log item

Water and earth runes Small quantities

Coins Very small amounts (1–20 GP)

Unlit torch Common but not useful

Gold bar Rare

Oil lantern frame Useful for making better light sources

Gem drop table access 4/128 chance

Easy clue scrolls Moderate chance; worth doing for fun and rewards

Average kill value: About 87 GP.

Conclusion: Just focus on completing your task — loot only swamp tar, clue scrolls, and maybe gems if you get lucky.

Cave Slime Locations

You have two primary options for killing cave slimes in OSRS:

1. Lumbridge Swamp Caves

Best for: Low-to-mid level players

How to get there:

Lumbridge Home Teleport → Run southwest into the swamp

Fairy ring code: DIS → Run northeast

Amulet of Glory: Teleport to Draynor Village → Run southeast

If it’s your first time entering, you’ll need a rope to climb down into the caves. Once inside:

Light source ready: It’s pitch dark without it.

Avoid wall beasts: Use run energy and click carefully past them unless you brought a spiny helmet.

Where to find cave slimes: After entering, run west and then slightly south. You’ll find multiple cave slimes in this area.

The spawn rate here is slow but steady enough for small to mid-size Slayer tasks (~20–50 kills).

2. Dorgesh-Kaan South Dungeon

Best for: Higher-level players or those looking for faster kills

How to get there:

Fairy ring code: AJQ → Direct teleport

Alternative: Travel via Kalphite Lair (BIQ) → Run west and north

Another option: Shantay Pass → 5 GP → Run southwest to entrance

Inside:

There are three cave slime spawns near the entrance.

More slimes can be found deeper in the dungeon, especially northeast and northwest.

Tip: Higher combat players can sweep through the northwest area faster because of the dense spawn groups.

Strategy Tips and Final Thoughts

Always use anti-poison: It’s the only real threat during this task.

Bring a safe light source: Bullseye lanterns won’t explode like candles can.

Low-defense players: Bring a few pieces of food to deal with poison or unlucky hits.

Higher-level players: Rush through with melee gear for fastest kill speeds.

Pick up swamp tar: If you plan to train Herblore or complete quests like Shades of Mort'ton later.

Don’t linger: You won’t make money here — finish your assignment and move on to more rewarding Slayer tasks.

Final Word

Cave slimes are one of the easiest Slayer tasks in Old School RuneScape, but they serve an important role: getting you through the early levels of Slayer quickly and safely. With a little preparation — primarily bringing an anti-poison potion and a light source — you’ll breeze through them without issue. Just be smart about inventory management, teleportation safety, and poison countermeasures.

Good luck on your Slayer journey, and may your next tasks be far more profitable and exciting!
