skill that provides passive bonuses at the expense of prayer points. Prayer points can be gained by burying bones from the Bank. Killing monsters while wearing the Bone Necklace will automatically bury bones and award twice the normal amount of prayer points. During Combat, a maximum of two prayers can be active at once. There is no limit to the amount of prayer points that the player can have. Raising Prayer to

will unlock the Prayer Skillcape for purchase from the Shop.

Prayer experience is earned when dealing damage to monsters while any prayers with a cost per player attack are active. The amount of Prayer experience earned is [math]\displaystyle{ \frac{1}{30} }[/math] or [math]\displaystyle{ 0.0\bar{3} }[/math] per point of damage dealt multiplied by the base prayer point cost per player attack. Note that the 'prayer point cost' is the base cost before any cost modifiers are applied, meaning that methods used by the player to either reduce or increase prayer costs do not affect the experience earned. This experience can be increased by 4% by equipping the Gold Emerald Ring, which along with the 1% increase from Pyro and 5% from Firemaking Skillcape provides a skill XP increase of 10%.

Prayer Point Acquisition Rates

Calculations
The general formula used for

Fishing
is [math]\displaystyle{ P \times A_F \times \tfrac{2^M \times \left (1 + C_M \right ) \times \left ( 1 + C_D \right ) + C_A}{S} }[/math], where:
  • [math]\displaystyle{ P }[/math] is the prayer points per fish, a constant of 3 for   Raw Skeleton Fish
  • [math]\displaystyle{ A_F }[/math] is the area's fish chance, a base of 95% (or 0.95) for the Secret Area
  • [math]\displaystyle{ M }[/math] is the number of things guaranteed to double the number of fish caught
  • [math]\displaystyle{ C_M }[/math] is the chance to double provided by the fish

  • [math]\displaystyle{ C_D }[/math] is the chance to double from all other sources, provided by a number of things such as the   Fishing Hook
  • [math]\displaystyle{ C_A }[/math] is the chance to gain 1 additional resource, provided by

, this is reduced further to [math]\displaystyle{ S = \tfrac{1.8 + 5.4}{2} = 3.6 }[/math] seconds, and can be reduced further still with

. The   Fishing Skillcape and  
Error creating thumbnail: File missing
Level 99
, when both are active [math]\displaystyle{ M = 2 }[/math] and so guaranteed doubling provides [math]\displaystyle{ 2^2 = 4 }[/math] times the usual number of fish. Assuming a somewhat optimal setup as per this sheet, the time between catches reduces to [math]\displaystyle{ S = 2.8 }[/math] seconds, chance to double becomes [math]\displaystyle{ C_D = 0.73 = 73\% }[/math], and the additional resource chance becomes [math]\displaystyle{ C_A = 0.03 = 3\% }[/math]. This assumes 10% chance to double and 10% interval reduction from

, as rolls higher than this require too much dust.

Alt.Magic
has the interval of 2 seconds. With   Amulet of Incantation, the Alt.Magic interval goes down to 1.8 seconds.

The earth rune expenditure can be mitigated by using the   Staff of Earth leaving two   Nature Runes per cast. It adds roughly [math]\displaystyle{ (1.3+2)/16/\frac{1}{1-0.8} = 0.04125 }[/math] seconds per a Blessed Offering cast if we consider the maximum preservation, mastery, mining without the God Upgrades

The rune expenditure can be mitigated further by the   Nature's Call Staff and the   Magic Skillcape, leaving only one   Earth Rune per cast. Using the God Upgrades, It can be sped up to roughly [math]\displaystyle{ (0.85+1.7)/16/\frac{1}{1-0.8} = 0.0319 }[/math] seconds per a Blessed Offering cast.


For

tasks

Slayer tasks do not directly generate many bones. Instead, the Prayer points are acquired by spending the

Error creating thumbnail: File missing
Slayer Coins

earned at the Shop on either   Standard Resupply or   Generous Resupply packs, which contain 500   Magic Bones and 1,000   Magic Bones respectively. (The   Basic Resupply provides a worse rate than the other two and should be avoided)

Both the Standard and Generous Resupply packs allow converting Slayer Coins into Prayer Points at a rate of 2  per Prayer Point. This means Slayer tasks begin generating 7 prayer points per second once the player can gain at least 50,400  per hour.

Bones

Bones can primarily be acquired by killing Monsters that are not in Dungeons. Alternative sources are:

Prayers

All prayers that provide a percentage increase apply multiplicatively, except for

Error creating thumbnail: File missing
Safeguard

and

Error creating thumbnail: File missing
Stone Skin

which provide flat increases to Damage Reduction. For example,

Error creating thumbnail: File missing
Mystic Might

's +15% Magic Evasion bonus will multiply the player's Magic Evasion Rating by 1.15 rather than directly providing a 15% chance to evade any Magic attack. Likewise, the +15% Magic Accuracy bonus it provides will multiply the player's Magic Accuracy Rating by 1.15 rather than simply adding 15% to their hit chance. Players can view the

Error creating thumbnail: File missing
Combat

page for more detail on how hit chance is calculated. The three Protection prayers are worded differently and behave differently from prayers that affect Evasion Rating. For example,

Error creating thumbnail: File missing
Protect from Magic

provides a flat 80% chance for the player to dodge any Magic attack, therefore using protection prayers when the monsters's chance to hit is 20% or lower is not advised as doing so would increase the monster's chance to hit.

Reducing Prayer Point Usage

To reduce the number of prayer points used by active prayers, players can take advantage of various sources granting modifiers that reduce the prayer point cost of prayers and/or provide a chance to preserve all prayer points the prayer would have used.

The prayer point cost reduction modifiers can reduce the cost of prayers to a minimum of 1 point per prayer, the only exception to this being that

Error creating thumbnail: File missing
Protect Item

is free when the   Gold Diamond Ring is equipped. Any flat prayer point reductions are applied before any percentage reductions, therefore in some specific cases some flat cost reductions provide no benefit. For example, consider a scenario where prayers with an odd prayer point cost are active while both the   Prayer Skillcape and   Priest Hat are equipped - in such a case, the Prayer Skillcape reduces the cost to 2 points regardless of whether the Priest Hat is equipped or not.

The chance to preserve prayer points provides a chance that active prayers will be used for free. The highest possible chance to preserve is currently 83%.

Damage dealt by failed

attempts does not currently count as an Enemy Attack for the purposes of spending prayer points, allowing the prayers

to be active while thieving for effectively zero cost as long as you have enough prayer points to turn them on. This may be a bug.
