Collection Log

Enter your RuneScape name to pull your real collection log from RuneProfile — owned slots get ticked and the simulator only counts new unlocks. (Your log must be synced via the RuneProfile RuneLite plugin first.)

Your RuneScape name

No log loaded — slots below are just this boss's collection log entries.

▸ Username not showing your collection log? Here's how to sync it

Your log is pulled from RuneProfile, which needs a free RuneLite plugin to upload it first:

In RuneLite, open the wrench (Configuration) → Plugin Hub.
Search RuneProfile and click Install.
Log into OSRS, open your Collection Log in-game and click through the tabs/pages you want tracked — the plugin only uploads pages you've actually opened.
The plugin uploads your profile to runeprofile.com automatically (or right-click its panel → Upload).
Come back here, type that exact name above, and hit 🔎 Fetch my collection log.

Heads up: RuneProfile shares your collection log only — kill counts aren't included, so enter those by hand where the simulator asks.

Still stuck? Open your RuneProfile JSON ↗, copy it all, and paste it here:
