Buy RS3 Pyre logs
Pyre logs are special logs used in RuneScape 3. They are made by adding sacred oil to normal logs. Players use them in the Shades of Mort'ton minigame to cremate Loar and Phrin shade remains. Each cremation gives 50 Firemaking experience, plus Prayer experience, along with coins or a key on a nearby stand.
The type of key you get depends on the shade remains you burn. Higher level shades leave higher level keys. This makes pyre logs a key part of unlocking rewards in Mort'ton.
Pyre logs also matter after the Legacy of Seergaze quest. Teak pyre logs or better can cremate Vyre corpses in the Columbarium under the Paterdomus temple. Magic and elder pyre logs can give a Shiny columbarium key there.
Pyre logs come in many types, from regular logs up to elder logs. Stronger logs need a higher Firemaking level and more doses of sacred oil to make. Buying pyre logs saves you the work of making sacred oil, restoring the temple, and treating each log by hand. Stock up on RS3 pyre logs and get straight to burning shades and collecting keys.
