The SFOTH sword series is a line of ten Roblox Limited gear items built around the swords from Sword Fights on the Heights IV, one of the platform's oldest active games. It began with Illumina and Darkheart in October 2009 and grew through 2014 with Ghostwalker, Venomshank, Windforce, Firebrand, Icedagger, and three "Dual" wield variants. Trader consensus currently ranks Darkheart as the family's most valuable piece even though it doesn't carry the highest RAP, a gap worth understanding before you buy any of them.
What Is Sword Fights on the Heights?
Sword Fights on the Heights (SFOTH) is a melee combat game built by Roblox staff member and administrator Shedletsky. It's one of the oldest continuously active games on the platform and is widely credited with kicking off the swordfighting genre that later spawned dozens of imitators. The original launched in April 2007 with nothing but sword combat, stripped of the guns and explosives that dominated brickbattling games at the time. A sequel, SFOTH II, followed in March 2008. The fourth version, SFOTH IV, arrived that June and has remained the game's standing version ever since, still playable today.
That longevity matters for the item line. Unlike most Limited series, which trace back to a single seasonal drop or contest, the SFOTH swords were sold as gear over a five-year stretch tied to one continuously running game.
From In-Game Weapons to Marketplace Gear
Each sword in the SFOTH IV Swords series started life as an in-game weapon inside Sword Fights on the Heights IV, and Roblox later sold matching versions as standalone LimitedU gear that any player could equip in other games. Most kept their original combat behavior. Ghostwalker, for instance, makes its wielder progressively more transparent with each kill, topping out at nine kills where the user becomes almost invisible. Darkheart heals its wielder for a share of the damage it deals. Windforce knocks back anything it touches. They're functional melee weapons with distinct mechanics, which is part of why the line still has a following among older players who remember using them.
Because they're gear rather than hats, they show up differently across the site too. If you're screening for them, the items leaderboard will surface them under gear rather than accessories.
The Full SFOTH Sword Lineup
The table below covers all ten members of the family, ordered by trader consensus street value (several of these older swords trade thin enough that RAP lags what buyers actually pay). Live RAP and copy counts are pulled from our items database as of this run.
| Sword | Released | Launch Price | Live RAP | Copies |
|---|---|---|---|---|
| Darkheart | Oct 13, 2009 | 2,000 R$ | 1,800,000 | 96 |
| Ghostwalker | Oct 29, 2010 | 12,000 R$ | 1,939,092 | 93 |
| Dual Darkhearts | Mar 1, 2013 | 60,000 R$ | 1,214,328 | 100 |
| Illumina | Oct 7, 2009 | 5,000 R$ | 2,632,887 | 93 |
| Firebrand | May 19, 2012 | 20,000 R$ | 931,357 | 100 |
| Dual Venomshanks | May 24, 2014 | 25,000 R$ | 466,550 | 100 |
| Windforce | Apr 13, 2012 | 15,000 R$ | 443,230 | 100 |
| Icedagger | Jun 15, 2012 | 25,000 R$ | 761,341 | 100 |
| Venomshank | Dec 28, 2011 | 5,000 R$ | 642,013 | 100 |
| Dual Illumina | Dec 21, 2012 | 40,000 R$ (gift box) | 745,337 | 451 |
A few notes on that table. Illumina, at 5,000 Robux, launched six days before Darkheart in October 2009, making it technically the older release, though the two are treated as a matched pair by most collectors. Dual Illumina didn't sell as a standalone catalog item at first; it came bundled two-to-a-box inside a 40,000 Robux gift called the Coolest Gift before becoming a tradeable Limited on its own in February 2013. It also ended up in a much larger run than the rest of the family, which is why its RAP and consensus value sit closer together than any other item in the series: it never got scarce enough to develop the same lag between RAP and what people actually pay.
Why Darkheart Outranks Higher-RAP Swords
RAP is an exponentially smoothed average of actual sale history. That's normally fine, but it breaks down on items that barely trade. Darkheart, Ghostwalker, and Illumina are all sixteen-plus years old at this point with only around 93 to 96 copies each, and most owners simply hold. When a sword like Darkheart only changes hands a handful of times a year, one or two sales at any price, high or low, can leave RAP sitting far from what a buyer would actually have to pay to pry a copy loose today.
That's exactly what's happened here. Illumina carries the highest RAP of the three original 2009-2010 swords, but trader consensus puts Darkheart well ahead of it, with Ghostwalker also passing Illumina despite a lower RAP. Dual Darkhearts shows the same pattern in miniature: its RAP sits mid-pack, but consensus treats it as one of the more valuable pieces in the whole series. On a thin, ancient gear item, RAP tells you what changed hands last.
Are the Dual Variants Worth a Look?
Three swords in the family got two-handed "Dual" versions: Dual Darkhearts (2013), Dual Illumina (2012), and Dual Venomshanks (2014). Each is a separate Limited, and the three behave very differently on the market. Dual Darkhearts trades like a proper gem: a 100-copy run and consensus value well above its RAP. Dual Illumina, with more than four times as many copies in circulation, behaves like a much more liquid, price-efficient item. Dual Venomshanks sits in between, closer in spirit to the original Venomshank than to the Darkheart pair.
If you're weighing which of the three to chase, copy count is doing most of the work in that price gap. Scarcity is what sets these apart. Nothing here is financial advice.
What Drives the SFOTH Sword Premium?
A few things stack on top of each other here. First, age: these are gear items from Roblox's first wave of Limiteds, before hats came to dominate the trading economy the way they do now. Second, function: unlike a fedora or a pair of horns, these can still be equipped and used as actual melee weapons in any game that allows gear, which keeps a small but real utility demand alive alongside pure collecting. Third, and probably most important, is the game itself. Sword Fights on the Heights IV never shut down and never got replaced, so the swords aren't relics of a dead game the way many older Limiteds are tied to events that no longer exist. Anyone can still go play SFOTH IV today and use the weapon these Limiteds are modeled on, which keeps the nostalgia current.
A Collector's Outlook
For a trader with a long horizon, the SFOTH swords sit in an unusual spot: genuinely old, genuinely functional, and genuinely thin-traded. That combination tends to reward patience and punish anyone trying to time a quick flip, since the same low sales volume that lets consensus value drift above RAP also means it can take a while to actually find a buyer at that price. Anyone considering a position here should treat the RAP figures in the table as a floor reference, and expect real offers to take longer to materialize than they would on a high-volume hat Limited. This isn't financial advice, and Roblox trading carries real risk regardless of how established an item family looks.

FAQ
What is the SFOTH sword series?
It's a set of ten Roblox Limited gear items modeled on weapons from Sword Fights on the Heights IV, sold between October 2009 and May 2014: Illumina, Darkheart, Ghostwalker, Venomshank, Windforce, Firebrand, Icedagger, and Dual versions of Darkheart, Illumina, and Venomshank.
Which SFOTH sword is the oldest?
Illumina, published October 7, 2009, six days ahead of Darkheart. Both are treated as the series' founding pair by collectors.
Why does Darkheart trade above Illumina despite a lower RAP?
Both items trade rarely enough, under 100 copies each, that RAP lags behind what buyers are actually willing to pay. Trader consensus currently values Darkheart above Illumina and Ghostwalker even though Illumina's RAP is the highest of the three.
Are these hats or gear?
Gear. Each sword can be equipped as a melee weapon in games that allow gear items, in addition to sitting in inventory as a collectible. That's different from the hat-based Limited families that make up most of the classic market.
Is Sword Fights on the Heights IV still playable?
Yes. It has remained Roblox's standing version of the game since June 2008 and is still active, which is part of why the swords tied to it keep collector interest.
