Formula Explained: This calculator first determines the total experience needed to reach your target Prayer level from your current level, accounting for any existing XP and bonus XP from lamps/quests. It then calculates the effective experience gained per bone/item based on your chosen bone type, burying method, and any percentage XP bonuses. Finally, it divides the total required XP by the effective XP per bone to give you the total number of bones or items you'll need. Estimated cost is provided based on a placeholder price, which you should verify on the Grand Exchange.

What is Runescape Prayer?

Prayer is one of the 23 skills in Old School Runescape (OSRS) and a vital part of a player's journey, impacting combat, quests, and overall utility. The runescape prayer calculator on this page is designed specifically for OSRS players to plan their training efficiently. Prayer points are consumed to activate various prayers, which provide temporary buffs such as increased attack, strength, defence, or protection from specific attack styles (e.g., Protect from Melee, Magic, Ranged). It also includes utility prayers like Rapid Heal and Rapid Restore. Unlike many other skills, Prayer is primarily trained by burying bones or offering them at altars, requiring a significant investment of time or gold.

Common Misunderstandings About Prayer Training

Many players perceive Prayer as solely an "expensive" skill. While it can be costly, understanding the different training methods and utilizing a runescape prayer calculator can help optimize expenses. Relying only on burying bones is often the slowest and least XP-efficient method. Furthermore, some players overlook the impact of XP bonuses or the significant XP awarded by quests, which can save millions of gold and hours of grinding.

Runescape Prayer Calculator Formula and Explanation

Our runescape prayer calculator uses a straightforward yet powerful formula to determine your Prayer training requirements. The core idea is to calculate the total experience you still need and then divide it by the effective experience you gain per bone or item, factoring in all bonuses.

The Core Formulas:

Required XP = (Total XP for Target Level - Total XP for Current Level) - Current Prayer XP - XP from Lamps/Quests

Effective XP per Bone = Base Bone XP * Burying Method Multiplier * (1 + XP Bonus Percentage / 100)

Bones/Items Needed = Ceiling(Required XP / Effective XP per Bone)

Variable Explanations:

Variable Meaning Unit Typical Range
Current Prayer Level Your character's current Prayer skill level. Levels 1-99
Target Prayer Level The desired Prayer skill level. Levels 1-99
Current Prayer XP The total experience points your character has in Prayer. XP 0 to ~13,034,431 (for level 99)
XP from Lamps/Quests Any additional experience from rewards that you will apply. XP 0 - Varies
Base Bone XP The raw experience given by a specific bone or item when buried normally. XP per item 4.5 (Normal Bone) to 150 (Superior Dragon Bone)
Burying Method Multiplier A multiplier applied based on the chosen training method (e.g., Gilded Altar, Ectofuntus). Unitless multiplier 1 (Burying) to 4 (Ectofuntus)
XP Bonus Percentage Additional percentage bonus from items like the Prayer outfit or Holy Wrench. % 0-10%
Bones/Items Needed The calculated number of bones or items required to reach the target. Count (unitless) 1 to Millions

Practical Examples Using the Runescape Prayer Calculator

Let's look at a couple of scenarios to demonstrate how our runescape prayer calculator can be used to plan your training effectively.

Example 1: Efficient Training to Level 70 for Piety

  • Goal: Reach Prayer Level 70 for the Piety prayer.
  • Current Prayer Level: 1
  • Target Prayer Level: 70
  • Current Prayer XP: 0
  • XP from Lamps/Quests: 0
  • Bone/Item Type: Dragon Bone (72 XP)
  • Burying Method: Gilded Altar (with 2 burners) (3.5x XP multiplier)
  • XP Bonus (%): 0%
  • Results:
    • Total XP to Target: 73,729 XP
    • Remaining XP Required: 73,729 XP
    • Effective XP per Bone: 252 XP (72 * 3.5 * 1)
    • Bones Needed: 293 (Dragon Bones)
    • Estimated Cost: Varies (check Grand Exchange for Dragon Bone prices)

This shows a relatively quick and efficient path to a mid-level Prayer goal crucial for many PvM activities, using one of the most common high-tier bones.

Example 2: The Road to 99 Prayer with Ourg Bones

  • Goal: Max out Prayer to Level 99 from a mid-level.
  • Current Prayer Level: 70
  • Target Prayer Level: 99
  • Current Prayer XP: 73,729 (XP for level 70)
  • XP from Lamps/Quests: 50,000 (e.g., from quest rewards like Bone Voyage or XP lamps)
  • Bone/Item Type: Ourg Bone (140 XP)
  • Burying Method: Chaos Altar (Wilderness) (3.5x XP multiplier)
  • XP Bonus (%): 2.5% (from full Prayer outfit)
  • Results:
    • Total XP to Target: 13,034,431 XP
    • Remaining XP Required: 12,910,692 XP
    • Effective XP per Bone: 499.75 XP (140 * 3.5 * (1 + 0.025))
    • Bones Needed: 25,836 (Ourg Bones)
    • Estimated Cost: Varies significantly (Ourg Bones are expensive, but Chaos Altar offers a 50% chance to save bones if offered to the NPC)

This example highlights how high-tier bones, efficient methods, and even small XP bonuses can significantly impact the total number of items needed for 99 Prayer. The Chaos Altar, while risky due to the Wilderness, is popular for its XP rate and bone-saving potential.

Key Factors That Affect Runescape Prayer Training

Optimizing your Prayer training involves understanding several key factors that influence both the speed and cost of gaining experience. Our runescape prayer calculator helps you model these variables.

  1. Bone Type: The most significant factor. Higher-tier bones (e.g., Dragon, Ourg, Superior Dragon) offer substantially more base XP per item but are generally more expensive. Balancing cost and XP gain is crucial.
  2. Burying/Offering Method: This determines the XP multiplier applied to each bone.
    • Burying: 1x XP, slowest, cheapest (no additional costs).
    • Prayer Altar (POH): 3x XP (with 2 lit burners), requires a Construction level, but is private and safe.
    • Gilded Altar: 3.5x XP (with 2 lit burners in a player-owned house), very popular, efficient, and safe. Often done in public houses.
    • Chaos Altar: 3.5x XP (Wilderness), offers a 50% chance to save bones when offered to the NPC, making it potentially cheaper. However, it carries significant PvP risk.
    • Ectofuntus: 4x XP, highest multiplier, but extremely click-intensive and requires collecting buckets of slime and grinding bones. Less popular due to effort.
  3. XP Bonuses: Small percentage bonuses can add up over millions of XP. The full Prayer outfit offers 2.5% bonus XP, and the Holy Wrench (after Rum Deal quest) provides a 1% bonus to prayer restoration, which for some methods can be interpreted as an XP gain equivalent.
  4. Quest Rewards: Many quests offer Prayer XP lamps or direct XP rewards. Completing these before or during training can significantly reduce the number of bones you need. Notable quests include Recruitment Drive, Holy Grail, and the Great Brain Robbery.
  5. Grand Exchange (GE) Prices: The market price of bones fluctuates. Monitoring these prices and buying bones when they are cheaper can save millions of GP. This calculator does not dynamically pull GE prices, so always check current rates.
  6. Alternative Methods: While bones are primary, other methods exist. Reanimating ensouled heads (from Slayer tasks) offers varying Prayer XP based on the head type, but also requires Magic XP. Offering shade remains in Mort'ton is another option.
