When saving up 260,000 Tokkul for an Uncut Onyx, the biggest fear players have is losing millions of GP to the TzHaar shop’s “overstock penalty.” The OSRS engine automatically lowers the price a shop pays you for an item as its stock increases above the default amount.
But does this mean you need to hop worlds every time you sell 5 runes? The answer depends entirely on which rune you are selling.
Here is the exact mathematical breakdown of when you must world hop, and when you are just wasting your time.

The Chaos Rune Myth (Why Hopping is a Waste of Time)
The vast majority of players fund their Onyx using Chaos Runes because they can be quickly bought in packs from Aubury or Ali Morrisane. A persistent community myth is that you need to sell Chaos runes in small batches (5 or 10) and constantly world hop to maximize your Tokkul yield.
The Math:
- Onyx Cost (with Karamja Gloves): 260,000 Tokkul
- Chaos Rune Base Sell Price: 9 Tokkul
- Chaos Rune Floor Sell Price: 9 Tokkul
Because the absolute minimum floor price the TzHaar-Mej-Roh’s Rune Store will pay for a Chaos Rune is 9 Tokkul (with Karamja gloves equipped), the overstock penalty effectively does not exist for this specific item. Furthermore, in the main game, almost every single world is perpetually overstocked by tens of thousands of runes from other players.
- The Meta: Equip your Karamja Gloves, go to any world, and spam “Sell 50” until you hit 28,889 Chaos Runes sold. World-hopping here will save you exactly 0 GP and cost you hours of unnecessary clicking.
When You MUST World Hop (Death Runes & Arbitrage)
If you are an Ironman selling Death Runes, or a player utilizing restricted game modes (like Leagues) where shop restocks are instanced, world hopping is strictly required to prevent massive GP loss.
When selling Death Runes, the price drops rapidly. Selling a full inventory dump (50 at a time) crashes the average Tokkul yield per rune well below the profitable threshold.

The “Sell 10” Strategy
To optimize your GP-to-Tokkul ratio, you must sell in smaller batches before the price decay ruins your margins. If you want to skip the manual math, you can plug your inventory into our OSRS Tokkul Calculator to instantly simulate how many total Tokkul your specific stack of runes will yield under these different hopping methods.
| Selling Method (Death Runes) | Batch Size | Avg. Tokkul per Rune | Tokkul per 50 Runes |
| The Dump | Sell 50 at once | ~38.0 | ~1,900 |
| The Sweet Spot | Sell 10, then hop | 46.4 | 2,320 |
| The Min-Max | Sell 5, then hop | 48.2 | 2,410 |
Note: Math assumes Karamja Gloves 1+ are equipped.
Calculating the Value of Your Time
Is it mathematically worth selling 5 at a time instead of 10? You have to factor in the engine’s world-hop delay.
An average OSRS world hop takes roughly 3 to 4 seconds.
- If you sell 10 Death Runes at a time, you are hopping less frequently, generating roughly 3.96 GP per Tokkul cost efficiency.
- If you sell 5 at a time, your efficiency increases slightly, but you spend nearly twice as much time staring at a “Please Wait” screen to clear your inventory.
For 95% of players, selling 10 Death Runes per world is the mathematical sweet spot. It balances the mitigation of the overstock price penalty with the real-world time lost to server hopping.
Conslusion
Don’t let outdated community myths dictate how you spend your time at the TzHaar shops. If you are dumping Chaos Runes to fund your Onyx, keep your Karamja Gloves equipped and spam “Sell 50” on any populated world—the rigid 9-Tokkul floor guarantees you won’t lose a single point of value.
However, if you are an Ironman liquidating Death Runes or higher-tier items, the “Sell 10 and Hop” method is your undisputed sweet spot. It perfectly balances preserving the value of your rune stack with minimizing the time wasted staring at the world-hopper loading screen.
