OSRS Cow Boss Guide: Requirements, Mechanics, Drops & Hard Mode

Overview: Brutus (the Cow Boss) at a Glance

Brutus (the Cow Boss) is a full boss in the beginner boss group, rated 1 out of 5 in our boss index and normally fought solo or team.

Before you can fight Brutus (the Cow Boss) you need The Ides of Milk.

Hard Mode difficulty spike is what this fight actually asks of you, and it is the thing standing between you and mooleta.

Its own attack is melee (crush), so Protect from Melee is the prayer it asks for.

In our index it sits in the beginner boss group at difficulty 1 of 5, where kill times come down to Hard Mode difficulty spike.

Access Requirements

Brutus (the Cow Boss) is gated behind The Ides of Milk.

The Ides of Milk also tends to sit alongside the other beginner 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

Brutus (the Cow Boss) is found in the Lumbridge cow field.

Walk east from Lumbridge to the cow field. It is free-to-play and about as accessible as content gets — the gate is the quest, not the journey.
