Cave slimes are Slayer monsters that require level 17 Slayer to kill. They inflict poison regardless of whether they do damage or not, so it is advised that the player brings a form of anti-poison when fighting them. As they are located in the Lumbridge Swamp Caves, a rope is needed if you have not entered the dungeon before. A light source is also required, but be aware that any exposed light sources (such as a candle) may explode, dealing up to 25% of the current Hitpoints level in damage if you go into the northern spawning room. A good option for an enclosed light source is an emerald or sapphire lantern. If a player is next to a cave slime when they attack they may be poisoned even if the slime does not retaliate.

Cave slimes are found in two rooms of the caves. Open light sources will flare brightly, and ignite gas in the northern room, however the entire southern room is risk free. For either room you will have to pass by a wall beast, so head protection (spiny helmet/Slayer helmet) can be helpful to avoid damage.

They have a guaranteed drop of roughly 3.5 swamp tar per kill, making them a decent low energy cost method for Ironmen to gather tar.
