Calculator:Prayer/Bones

This section or article is incomplete. Reason: ectofuntus no longer needs pots and buckets, so the XP rates are certainly incorrect; altar might need verification too; the template should be fixed to correctly display ectofuntus rates with ashes You can discuss this issue on the talk page or edit this page to improve it.

This is a static calculator. It does not take user inputs, but it does use changing prices from the Grand Exchange Market Watch. If prices appear to be outdated, purge the page by clicking here.

Bone burial

The Bone burial calculator is a calculator that can be used to efficiently train Prayer. This particular skill is noted for being something that can be "purchased", and none of this activity is "profitable" in terms of purchasing the bones from the Grand Exchange or from another player. Many of these bones sell in large enough quantities that the prices change on a daily basis.

The experience point value for using altars in player-owned houses and the Ectofuntus are included as comparisons for performing skills based on how much the player can earn, and how quickly the player can gain experience from both methods.

Assumptions

• The cost of using the player-owned house as a burial site includes the cost of Clean marrentill at the current rate of 2,956 coins each.
• The player could be teleporting to the player-owned house for faster training. If the player does so they will require runes.
• Both burners are used.

Prayer experience rate

The Prayer experience rate calculator attempts to calculate how quickly a player can "earn" experience points for each bone type, depending on the location where they are performing the task.

Assumptions

• Bank
  • The player buries an average of 3600 bones per hour. With the release of the Action Bar from the Evolution of Combat, these xp rates are easier to get.

• Ectofuntus
  • The player has at least level 58 Agility to use the shortcuts to the slime pool. It will take the player longer if they do not use these shortcuts.
  • The player is able to acquire 900 Buckets of slime per hour, or worship 1300 times once they have enough slime and bonemeal/ashes banked. Therefore when worshipping with ashes, the player will spend an average of 36 minutes of each hour acquiring 540 buckets, and the remaining 24 minutes worshipping 520 times, giving an overall average of 530 ashes used per hour.
  • When bones need to be ground, the overall rate drops to 270 bones per hour.
  • All of the above assumes that no familiar is used.

• Player-owned house (POH)
  • The player makes approximately 40 trips per hour from the bank to the house, teleporting both ways using the Rings of duelling and PoH Teletabs.
  • It is assumed that no beast of burden is used

Note that demonic ashes do not need to be ground first, the consume rate is about 150% of that of bones.
