What is OSRS Chinning?

In Old School RuneScape (OSRS), “chinning” refers to a popular high-level Ranged training method that utilizes the powerful “Throwing Knife” ammunition, commonly known as “chins.” These chins are fired from a special “Chinchompa” weapon (Red, Blue, or Black). The primary advantage of chinning is its ability to hit multiple targets simultaneously within a small area, making it incredibly efficient for training Ranged experience, especially when dealing with densely packed monsters. This method is particularly favored by players aiming for very high Ranged levels quickly, despite its significant monetary cost. Who should use it? Players seeking the fastest Ranged experience gain, particularly from level 70+ Ranged, who have a substantial budget to fund the training. Common misconceptions include thinking chinning is affordable or that it’s the only viable high-level Ranged training method; both are generally untrue.

OSRS Chinning Calculator: Formula and Mathematical Explanation

The OSRS chinning calculator works by first determining the total Ranged experience required to reach your target level from your current level. Then, it calculates how many chins are needed based on the experience provided by each chin. Finally, it estimates the total cost and time involved, considering factors like inventory management and average banking speed.

Step-by-Step Derivation

1. Experience Required: The total experience needed to advance from your current Ranged level to your target Ranged level is calculated using the game’s internal experience table. This is a cumulative value.
2. Total Chins Needed: Divide the total experience required by the experience gained per individual chin (e.g., per Dragon Bone thrown).
3. Chins Per Trip: Determine how many chins can be brought per inventory trip. This is calculated as (Total Inventory Slots – 1 for a placeholder item like a ring) / (Inventory Slots per Chin). The “-1” accounts for potentially bringing a ring or other item, or simply assuming one slot is reserved.
4. Number of Trips: Divide the Total Chins Needed by the Chins Per Trip to find the total number of trips to the bank required.
5. Total Cost (Bones): Multiply the Total Chins Needed by the Grand Exchange (GE) price of a single Dragon/Long Bone (which acts as the “chin”).
6. Estimated XP/Hour: This is a more complex estimation. It involves factoring in the chins thrown per trip, the average time for a single trip (including banking, running, and throwing), and scaling it to an hour. A common assumption for trip time is around 3.6 minutes (216 seconds) per inventory, which includes banking.
7. Total Time (Hours): Multiply the Number of Trips by the average trip time (converted to hours) to get the total estimated training duration.

Practical Examples (Real-World Use Cases)

Example 1: Mid-Level Push

A player wants to train their Ranged level from 70 to 90. They have a budget and are using Dragon Bones as their “chins”.

• Current Ranged Level: 70
• Target Ranged Level: 90
• Dragon Bone Price: 400 coins
• XP Per Chin: 60
• Inventory Size: 28
• Inventory Slots per Chin: 1

Calculator Output:

• Total XP Gained: ~1,432,727 XP
• Total Chins Needed: ~23,879
• Total Cost (Bones): ~9,551,600 coins
• Estimated XP/Hour: ~300,000 – 400,000 XP/Hour (depending on banking speed)
• Total Time (Hours): ~4 – 5 hours

Interpretation: This example shows that reaching level 90 from 70 via chinning requires a significant investment (nearly 10 million coins) and a moderate time commitment. The XP/hour is very high, making it a fast, albeit expensive, training method.

Example 2: Max Cape Grind

A player is aiming for the Max Cape and needs to train Ranged from 90 to 99. They are using Blue Chinchompas, which are more expensive but offer slightly less XP per throw.

• Current Ranged Level: 90
• Target Ranged Level: 99
• Blue Chinchompa Price: 600 coins
• XP Per Chin: 50 (as an example, actual varies slightly)
• Inventory Size: 27 (using a Ring of Wealth)
• Inventory Slots per Chin: 1

Calculator Output:

• Total XP Gained: ~3,113,040 XP
• Total Chins Needed: ~62,261
• Total Cost (Chins): ~37,356,600 coins
• Estimated XP/Hour: ~250,000 – 350,000 XP/Hour
• Total Time (Hours): ~9 – 12 hours

Interpretation: Training the final 9 levels of Ranged using chins is extremely costly (over 37 million coins). The XP rates are still high, but the cost-benefit analysis becomes crucial here. Players might consider alternative methods like Nightmare Zone or Brutal Black Dragons for lower cost at these high levels. This highlights the importance of budget considerations for endgame training.

Key Factors That Affect OSRS Chinning Results

• Bone/Chin Price Fluctuation: The Grand Exchange price of Dragon Bones or Chinchompas is the single biggest factor in cost. Prices can change daily, significantly impacting the total expense. Always check the GE before committing to a long training session.
• Experience Per Item: The exact XP value per thrown item can vary slightly based on game updates or specific mechanics (e.g., main-hand vs. off-hand). Using the correct XP rate is crucial for accurate calculations.
• Banking Speed and Efficiency: The time it takes to run to the bank, deposit items, withdraw more ammunition, and return to your training spot directly affects your XP/hour. Faster banking means higher XP rates. Optimal setups and routes minimize downtime.
• Inventory Management: Your chosen inventory size (e.g., 26, 27, or 28 slots) dictates how many chins you can bring per trip, directly influencing the number of trips required and thus the overall time and effort.
• Monster Aggression and Density: While not directly in the calculator formula, the effectiveness of chinning depends on training at a location with densely packed, aggressive monsters that can be lured into a tight area. This maximizes the multi-target aspect.
• Player Focus and Stamina: Chinning requires consistent attention. Fatigue or distractions can lead to slower banking, missed throws, or inefficient positioning, reducing the achievable XP/hour.
• Item Availability: Ensuring a steady supply of the chosen ammunition (Dragon Bones or Chinchompas) on the Grand Exchange is important for uninterrupted training.
• Leveling Curve: The amount of XP required increases significantly at higher levels (90-99). This means that while the XP per chin remains constant, the total number of chins and cost escalates dramatically as you approach max Ranged.

Frequently Asked Questions (FAQ)

Q: What is the best Ranged level to start chinning?

A: Chinning becomes highly efficient from Ranged level 70 onwards, especially when using Dragon or Blue Chinchompas. However, it can be used earlier if budget allows.

Q: Are Dragon Bones or Chinchompas better for chinning?

A: Dragon Bones (thrown as Dragon Claws) offer a good balance of XP and cost for many players. Blue Chinchompas generally offer slightly higher XP rates but are more expensive. Red and Black Chinchompas are typically used for specific, very high-level training scenarios or against certain monster types due to their faster projectile speed and higher cost.

Q: How much does it cost to go from 70 to 99 Ranged using chins?

A: This can vary wildly based on the price of ammunition, but estimates often range from 40 million to over 100 million coins for the entire journey, depending heavily on the specific chins used and GE prices.

Q: Can I use this calculator for other Ranged training methods?

A: This calculator is specifically designed for methods using thrown ammunition like Dragon Bones or Chinchompas, which hit multiple targets. It is not suitable for methods like cannoning or using ranged bolts on single targets.

Q: What is the fastest way to chin?

A: The fastest way involves maximizing XP per hour by using the highest XP-per-chin method (usually Blue Chinchompas, main-hand), training at a location with dense, easily lured monsters (like the Scorpia area in the Wilderness, or specific areas in the God Wars Dungeon), and achieving very fast banking times.

Q: Is chinning profitable?

A: No, chinning is almost always a net loss in OSRS. It is a “pay-to-win” experience training method where you spend significant amounts of in-game currency for rapid experience gains. Profitability might only occur in extremely niche scenarios with highly volatile market prices or during specific events.

Q: How do I calculate the XP per hour accurately?

A: The XP/hour calculation in the calculator is an estimate. It typically assumes a standard trip time (e.g., 3.6 minutes per inventory). Your actual XP/hour will depend on your specific banking speed, movement efficiency, and the density of monsters.

Q: Can I use this calculator with Ring of Wealth for increased magic find?

A: Yes, you can adjust the ‘Inventory Size’ to 27 if you are using a Ring of Wealth, as it takes up one inventory slot. This will slightly reduce the number of chins per trip but is often worth it for the potential drops from monsters.
