Master Completionist Cape Guide — RuneScape 3 Requirements & Checklist

Completionist Cape and Master Max Cape held at once — no independent requirements beyond its two prerequisites.

Prerequisites

Master Completionist Cape requires Completionist Cape and Master Max Cape first.

Nothing new to grind both prerequisites — Completionist Cape and Master Max Cape — are already tracked on their own tabs; once each reads 100%, this one is automatically satisfied too.
Not purchased — admired wear the master max cape, keep the completionist cape in your inventory (worn at least once), then admire the Ornate Grave in Falador Park and pick the Completionist cape option.
