What is OSRS Prayer Training?

OSRS Prayer training refers to the process within Old School RuneScape where players train the Prayer skill. This skill is crucial for various combat and utility functions, providing powerful buffs like protection prayers, offensive prayers, and telekinetic abilities. Efficient prayer training often involves using bones on altars or other specific items to gain experience points (XP) towards the next level. The goal is typically to reach level 99, the maximum, for the best possible benefits and achievement.

Who should use OSRS Prayer training calculators? Anyone looking to train their Prayer level in Old School RuneScape, especially those who want to:

  • Minimize the Gold Per Hour (GP/HR) cost of training.
  • Maximize the Experience Per Hour (XP/HR) gained.
  • Understand the total cost and time investment required to reach a specific Prayer level.
  • Compare different prayer training methods to find the most suitable one for their budget and efficiency goals.
  • Players engaging in bossing, skilling, or questing often require higher Prayer levels for prayer bonuses and sustained combat.

Common Misconceptions about OSRS Prayer Training:

  • “All bones are the same”: Different bones offer vastly different XP rates and costs. Some are extremely cheap but slow, while others are very fast but expensive.
  • “Only bones work”: While bones are the most common, methods like Ensouled Heads, Ectofuntus, and even specific combat strategies can also train Prayer.
  • “Prayer training is always expensive”: While many high-XP methods are costly, players can find more budget-friendly options that are slower but still effective, especially at lower levels or with specific drops.
  • “XP rates are static”: The XP rates and costs can fluctuate based on Grand Exchange prices, player-driven demand for certain items, and updates to the game.

OSRS Prayer Training Formula and Mathematical Explanation

Calculating the XP and cost for OSRS Prayer training involves several key components. The core idea is to determine how much experience is needed, how much XP each item or action provides, and the cost associated with acquiring those items.

Step 1: Calculate Total XP Needed

The total experience required to reach a target level from a current level is calculated by summing the XP required for each level between the current and target levels.

Total XP Needed = Total XP at Target Level - Total XP at Current Level

The experience required for each level in RuneScape follows a specific formula: XP for Level N = floor(300 * 2^(N-1) / 1.1). However, for practical purposes, pre-calculated tables are used.

Step 2: Determine XP per Item/Action

Each training method uses specific items (like bones) or actions that grant a fixed amount of Prayer XP. For example, a standard Bone on an Altar gives 12 XP, Dragon Bones give 72 XP, and Superior Dragon Bones give 140 XP.

Step 3: Calculate Number of Items/Actions Needed

This is derived from the total XP needed and the XP gained per item/action.

Number of Items = Total XP Needed / XP per Item (Rounded up to the nearest whole number)

Step 4: Calculate Total Cost

This involves multiplying the number of items needed by the cost per item. The cost per item can fluctuate based on Grand Exchange prices.

Total Cost = Number of Items * Cost per Item

If a method provides GP/HR, this can offset the total cost. The effective cost would then be Total Cost - (Time to Train in Hours * GP/HR).

Variable Explanations

Here’s a breakdown of the variables used in our OSRS Prayer Training Calculator:

Variable Definitions
Variable Meaning Unit Typical Range
Current Level The starting Prayer level of the player. Level 1 – 98
Target Level The desired Prayer level to achieve. Level 2 – 99
XP Needed The total amount of Prayer experience required to go from the current level to the target level. XP 0 – ~13,000,000
XP Rate (XP/HR) The estimated experience gained per hour for a specific training method. XP/Hour ~10,000 – ~200,000+
Items/Bones Needed The total quantity of the primary item (e.g., bones, ensouled heads) required. Count 0 – Millions
Cost per Item/Bone (GP) The current Grand Exchange price or estimated cost for a single unit of the training item. GP ~10 – ~5,000+
Total Cost (GP) The total estimated cost in Gold Pieces to achieve the target level using the selected method. GP 0 – Billions
GP Per Hour (Optional) The estimated Gold Pieces earned or saved per hour while training Prayer using specific methods. GP/Hour 0 – ~500,000+

Practical Examples (Real-World Use Cases)

Let’s look at a couple of scenarios for OSRS Prayer training:

Example 1: Budget Training with Standard Bones

Scenario: A player wants to train from Prayer Level 43 (completed Dragon Slayer I) to Level 70 using standard bones on a Player Owned House altar. They estimate they can get 200 bones per inventory and have a Prayer XP rate of roughly 45,000 XP/HR.

  • Current Level: 43
  • Target Level: 70
  • Method: Standard Bones on Altar (POH)
  • XP Rate: 45,000 XP/HR
  • Cost per Bone (Est.): 60 GP

Calculation:

  • XP Needed for Level 70 from 43: ~130,622 XP
  • XP per Standard Bone: 12 XP
  • Number of Bones Needed: 130,622 XP / 12 XP/Bone ≈ 10,885 Bones
  • Total Cost: 10,885 Bones * 60 GP/Bone = 653,100 GP

Interpretation: To reach Level 70 Prayer from 43 using this method, the player will need approximately 10,885 standard bones and spend around 653,100 GP. At an XP rate of 45,000 XP/HR, this would take roughly 2.9 hours (130,622 XP / 45,000 XP/HR).

Example 2: High-Level Training with Superior Dragon Bones

Scenario: An experienced player wants to push their Prayer level from 75 to 99 using Superior Dragon Bones at a Morytania Altar. They can achieve a high XP rate of 180,000 XP/HR.

  • Current Level: 75
  • Target Level: 99
  • Method: Superior Dragon Bones (Morytania)
  • XP Rate: 180,000 XP/HR
  • Cost per Superior Dragon Bone (Est.): 1,950 GP

Calculation:

  • XP Needed for Level 99 from 75: ~8,856,964 XP
  • XP per Superior Dragon Bone: 140 XP
  • Number of Superior Dragon Bones Needed: 8,856,964 XP / 140 XP/Bone ≈ 63,265 Bones
  • Total Cost: 63,265 Bones * 1,950 GP/Bone ≈ 123,366,750 GP

Interpretation: Achieving Level 99 Prayer from 75 using Superior Dragon Bones is a significant investment, costing approximately 123.4 million GP. It requires around 49.2 hours of training (8,856,964 XP / 180,000 XP/HR) at this high XP rate.

Key Factors That Affect OSRS Prayer Training Results

Several factors can significantly influence the time, cost, and efficiency of your OSRS Prayer training:

  1. Grand Exchange (GE) Prices: The cost of bones, ensouled heads, or other items is dictated by the GE. Prices fluctuate constantly based on supply and demand, affecting the total GP cost. Buying in bulk or during market dips can save money.
  2. XP Rate of the Method: Different methods yield vastly different XP/HR. Using Superior Dragon Bones at a Morytania Altar is much faster than standard bones on a basic altar, but also far more expensive.
  3. Player Skill and Focus: For methods involving actions like burying bones or using items quickly (e.g., Gilded Altar), player speed and focus directly impact the XP/HR achieved. Minimizing delays between actions is key.
  4. Availability of Resources: Certain items, like Dragon Bones or Superior Dragon Bones, can become scarce or expensive if demand spikes (e.g., during a Double XP event or popular bossing meta).
  5. Location and Altar Type: Training at the Morytania Temple offers a 15% XP bonus for burying bones, significantly boosting XP rates. Using a Player Owned House (POH) Gilded Altar with Offerings provides the highest potential XP rates but requires setup and often a host.
  6. Item Acquisition Method: Are you buying items directly off the GE, or are you obtaining them through PvM drops (like Wyvern Bones or Dragon Bones)? The latter can drastically change the effective cost, potentially making it much cheaper if you’re already engaging in that content.
  7. Banking Time and Efficiency: How quickly can you return to your training spot after banking? Efficient banking strategies, such as using player-owned house portals or specific teleport methods, minimize downtime and maximize XP/HR.
  8. In-Game Events: Special events like “Slayer Week” or “Double XP” (if ever implemented) can temporarily alter XP rates or item availability, impacting training efficiency and cost.

Frequently Asked Questions (FAQ)

What is the fastest way to train Prayer in OSRS?

The fastest methods generally involve using Superior Dragon Bones or Dragon Bones on a Gilded Altar in a Player Owned House with Offering upgrades, or burying bones at the Morytania Temple’s Ectofuntus. These methods can yield upwards of 150,000 – 200,000+ XP/HR but are very expensive.

What is the cheapest way to train Prayer in OSRS?

The cheapest methods often involve using standard Bones on a regular altar, or collecting Ensouled Heads from slayer monsters and using them at the মহিলার Altar. These methods are significantly slower but cost much less GP, sometimes even being profitable if you obtain the items yourself.

How much does it cost to get 99 Prayer?

The cost can vary drastically. Cheapest methods might cost around 5-10 million GP, while the fastest methods can cost upwards of 100-200 million GP. Using this calculator with your chosen method and prices will give you a precise estimate.

Should I train Prayer using bones or ensouled heads?

It depends on your budget and goals. Dragon Bones and Superior Dragon Bones offer higher XP rates per item. Ensouled Heads can be profitable if farmed effectively during Slayer tasks, making them a viable budget option, especially for mid-levels. Always check current GE prices.

Is the Morytania Prayer bonus worth it?

Yes, the 15% XP bonus for burying bones in the Morytania graveyard (at the Ectofuntus or using the burners) significantly increases your XP/HR compared to standard altars, making it a highly recommended method if available.

How do I get a Gilded Altar in my POH?

You need to have a Player Owned House, reach level 82 Construction, and then build a Gilded Altar using planks and gold bars at a standard Altar. You also need ‘The Art of Protection’ prayer book from the Library, and potentially access to a hosted altar service for the best rates.

Can I train Prayer through combat?

While not a primary training method, you do gain Prayer XP when using offensive prayers during combat. Some players passively train Prayer this way while training other combat skills, but it’s extremely slow and inefficient for dedicated Prayer leveling.

Does the OSRS Prayer Training Calculator account for player-owned house portals?

This calculator focuses on XP rates and item costs. It doesn’t directly factor in banking time or POH setup. However, the XP rates provided for Gilded Altar methods assume efficient use, which typically involves a well-organized POH with portals for faster banking.
