OSRS Shellbane Gryphon Guide: Slayer Requirements, Weight Mechanics & Drops

Overview: Shellbane Gryphon at a Glance

Shellbane Gryphon is a Slayer monster (often fought as a boss on task) in the Slayer boss group, rated 3 out of 5 in our boss index and normally fought solo.

Before you can fight Shellbane Gryphon you need Slayer unlock + weight mechanic prep.

Weight mechanics is what this fight actually asks of you, and it is the thing standing between you and slayer-only unique drops.

Its own attacks are melee and ranged, so Protect from Melee and Missiles both have a job.

In our index it sits in the Slayer boss group at difficulty 3 of 5, where kill times come down to weight mechanics.

Access Requirements

Shellbane Gryphon is gated behind Slayer unlock + weight mechanic prep.

Slayer unlock + weight mechanic prep also tends to sit alongside the other Slayer boss gates, so it is usually cheaper to clear them together than to come back for each one. The boss requirements checklist lists them by group.

Location and How to Get There

Shellbane Gryphon is found in a cave in the centre of the Great Conch.

Reach the Great Conch and take the central cave. You need Troubled Tortugans completed and a gryphons task, and gryphon tasks have to be unlocked from a Slayer master before they can be assigned.
