Buy RS3 Maple incense sticks
Maple incense sticks are incense sticks made from maple logs in RuneScape 3. They are stackable and tradeable, and they are free to play. They take up no weight, so a large stack is easy to carry.
Their main use is making accursed maple incense sticks. Combine 1 maple incense stick with 2 accursed ashes at level 40 Firemaking to get 54.2 Firemaking experience and 20 Prayer experience. From there, you can add a clean irit or a clean wergali to make irit or wergali incense sticks, which give 81.3 experience each.
Players can make these sticks by hand with 2 maple logs at level 40 Firemaking, but that takes 3 seconds per stick. Buying a stack skips that grind and lets you go straight to making the higher level sticks. The Quick-cense upgrade from Sydekix's Shop of Balance can speed up the crafting steps even more.
These sticks can also be disassembled for Invention. They fall under the Logs and hides category and give 1.2 Disassembly XP per item, with Simple parts as the most common material and a small chance of Living components.
