The Incense Brazier is a block added by Roots. It is used to perform Rituals. Right-clicking it with an item will add the item to the Casting Altar. Right-clicking it with an empty hand will remove the item. The Incense Brazier can be lit by right-clicking it with a Flint and Steel, which is required to complete most Rituals. Shift right-clicking a lit Incense Brazier will put it out.
