Prayer can be one of the most expensive skills to train in RuneScape. This article looks into how Prayer training cost can be reduced using Random Events, Bonus XP Weekends, Task Rewards and the Ectofuntus, as well as looking at the experience gained from different Bones and Demonic ashes.
The various Bones and Demonic ashes dropped by monsters are the regular way of earning Prayer experience, no matter how they are buried or offered. Here are experience rates earned from each type. The first number is the experience earned from simply burying or crushing the bones or scattering the ashes, the second for a Gilded Altar in a Player Owned House with both Incense Burners lit, and the third for using them on the Ectofuntus. Using an Altar that isn't Gilded, or without both Incense Burners lit, will reduce the experience.
Some bones actually make more financial sense to sell, and use the money raised to buy cheaper bones that give more experience. This is due more to the rarity of the bones; Dagannoth bones usually sell at more than three times the cost of Dragon bones, yet give less than double the experience. Ourg bones give almost double the experience of Dragon bones, yet cost almost five times as much. Wyvern bones actually give less experience than Dragon bones, but are nearly twice as expensive.
The advantage some of the more expensive bones give is the speed of training. That extra speed may not be worth it on a cost basis though.

A common reward from random events is an Experience lamp or Book of knowledge, both of which can be used to train Prayer. Random events are, of course, completely random, so cannot be depended on, but they can still be used to get some free experience.
Bonus XP Weekends are not a very effective way of reducing Prayer training costs. Because the bonus will not stack with the existing bonuses from items, such as the Wisdom aura or Brawling gloves, or means, such as the Ectofuntus or POH Altars, none of these training methods should be used. The only time the bonus from the Weekend will come into play is when burying Bones or scattering Demonic ashes.
The Ectofuntus is located in Morytania north of Port Phasmatys. Once the Ghosts Ahoy quest is completed, an Ectophial can be used to teleport to the Ectofuntus.
To train Prayer with the Ectofuntus, a player needs to worship there. Buckets of slime can be collected from the pool of ectoplasm below the temple, by using empty Buckets on it. Level 58 Agility will allow the use of an Agility shortcut, which makes getting to the pool much quicker.
Bones of all types are used in the grinder on the first floor with Empty pots in your inventory to create Bonemeal. Each Bonemeal requires one Empty pot and one Bones. All the Bones in your inventory can be ground, with enough pots, by right clicking "Fill Hopper" on the grinder. This part can be skipped if using Demonic ashes of any type.
One Bonemeal or any type of Demonic ashes and one Bucket of slime can be used to worship at the Ectofuntus. Doing so gains Prayer experience and Ectotokens.
The reward for completing the Medium Morytania Tasks, the Morytania legs 2, have two useful benefits for Prayer training. When worn, the player can teleport to the slime pit under the Ectofuntus five times per day, greatly speeding up slime collecting. Additionally, in return for completing the medium set, Robin in the Green Ghost Inn in Port Phasmatys will exchange 13 Bones for 13 Bonemeal of the same type and 13 Buckets of slime once per day.
