Gilded altar

A gilded altar is the highest level altar that can be built in the Chapel of a player-owned house. It can be used to recharge Prayer. When Bones or Demonic ashes are used with the altar, the player gains 250% of the experience normally received from simply burying the bones. Incense burners add an additive 50% experience per lit burner, achieving a maximum additive 100% bonus when both burners are lit (and a total of 350% of the normal experience received). All incense burners give the same amount of experience and require a clean marrentill and a tinderbox to light. Because of these bonuses, the gilded altar is a popular choice for players wishing to train Prayer.

The total cost to buy all the materials for the altar is coins, or  coins if purchased from the Stonemason and the Construction Supplies shop.



Requirements
A Construction level of 75 is required to build a gilded altar. It can theoretically be built as early as level 66 by using a crystal saw (+3 boost to level), a sculpting chisel (+1), and orange spicy stew with three doses of Orange spice (+5). However this is difficult to achieve due to the random (-5/+5) boost that the orange spicy stew provides.

An option with guaranteed success requires 68 Construction and a POH tea (+3) (from Teak shelves) which, combined with the crystal saw and the sculpting chisel, gives a total boost of +7.

Players often advertise their open altars on the official RuneScape forums in the Community section, on the Events thread. Yanille on World 31 also often hosts open altars, and so this world is commonly used for training Prayer.

Experience rates
Notes:
 * It is assumed that two incense, mahogany or marble burners are lit while using the Gilded altar.
 * The costs only include the cost of bones. The cost of clean marrentills used with the burners is not calculated.
