This article is about the Prayer-boosting feature in Mort Myre Swamp. For the means by which to craft nature runes, see Nature altar.
The Altar of Nature is a special altar that members can pray at, not only to replenish but also to boost their Prayer points by 20. This is one of three altars in RuneScape that will boost Prayer points by twenty, the other two are located in the Edgeville Monastery and Seers' Village (while wearing the seer's headband 3).
This altar is located at the southern end of Mort Myre Swamp, through a door on a small island accessible only via a bridge from the south. An empty druid pouch can be found in the chamber, on the floor next to the altar itself.
Before the quest, the altar looks blackened before it was restored. Many players recharge their Prayer there while on the way to Barrows. Note that the "swamp decay" effect is neutralised in the altar.
