A Rockslug is a Slayer monster that requires level 20 Slayer to kill. A bag of salt or a brine sabre is required to kill it. They are rarely killed due to their mediocre drops, which consists of low level ores and seeds. They may rarely drop the mystic gloves (light).
Locations[]
- Fremennik Slayer Dungeon
- Lumbridge Swamp Caves
- Dorgesh-Kaan South Dungeon (fairy ring code ajq )
Strengths and weaknesses[]
Rockslugs can only be successfully killed with a bag of salt, or by the use of a brine sabre. If the bag of salt is accidentally used before the Rockslug is reduced to less than 5 hitpoints, it will still be used up but have no effect. It would be wise to bring a few extra because of this (or you buy "Slug salter" from a slayer master). If a Rockslug's health is reduced to 1 but a bag of salt is not used on it, the Rockslug will stop retaliating and wander off, which will not count as a kill, unless you or someone else uses a bag of salt on it, in which case whoever dealt the most damage to it will get the kill.
