Kleos Series History: Roblox's Rarest Gladiator Helm

The Kleos series is a line of seven gladiator-helmet items Roblox has released since 2007, and it holds one of the strangest grails in the platform's history: The Kleos Aphthiton, a tournament prize with so little resale history that its RAP reads as untraded even though traders treat it as a multi-million-RAP-equivalent holding. Two items in the family are still regular catalog purchases, two are tradeable Limiteds, and three sit off-sale as retired event rewards.

What Is the Kleos Series?

Kleos began the same month as Roblox's flagship grail line. Coif of Glory launched August 10, 2007, first for 50 Tickets and then for 1,000 Robux once the Tickets sale window closed, and it's still buyable today off a dynamic price floor. According to the Roblox Wiki on Fandom, Kleos and the Dominus series were both conceptualized by the Roblox staffer Shedletsky, working under the handle Telamon at the time. That shared parentage shows in the design language: both lines lean on gladiator and warlord aesthetics, and both built their reputation around a single, extremely scarce top-tier item rather than a wide spread of similarly priced recolors.

Where Dominus grew into a sprawling family of a dozen-plus hats, Kleos stayed small. Seven items carry the name across nineteen years, and only two of them ever became tradeable Limiteds.

The Full Kleos Lineup

The order here reflects trader consensus, not raw RAP. RAP alone would rank Phóteinos above Aphthiton since Aphthiton has no recorded resale sales to average, but that's a case where RAP's math breaks down rather than a case where Phóteinos is genuinely worth more. More on that below.

The Kleos Aphthiton: Roblox's Strangest Grail

The Aphthiton is the reason this series gets talked about at all. Community-documented history on the Roblox Wiki holds that it was awarded to the top four finishers of the Roblox Grand Melee, a combat tournament held in August 2007, with additional copies granted afterward: one to a player named MacGeekPro in early 2008, and another to Herooftime101 in 2009 after a direct request to Shedletsky. It was converted to a tradeable Limited years later, in 2017. Our items database currently tracks eleven total copies in circulation.

That's an unusually direct paper trail for a 2007-era item, and it's also why the Aphthiton barely trades. With a double-digit copy count spread across long-time holders who mostly don't sell, recorded sales are rare enough that RAP, which is an exponentially smoothed average of actual transaction history, has nothing to smooth. Traders don't read that as "worthless." They read it as illiquid, and consensus street value for the Aphthiton sits in grail territory, far closer to the platform's most expensive Dominus hats than to its RAP figure of zero. This is the value-ranking divergence worth internalizing: a RAP of zero on an old, tightly-held item usually means nobody's tested the market lately, not that nobody wants it.

Kleos Phóteinos: The Series' Liquid Limited

Phóteinos is the more approachable half of the family. It launched during Bright Friday 2013, Roblox's post-Black-Friday sale window, and unlike the Aphthiton it trades often enough that RAP and trader consensus land in the same place. At roughly 1,000 copies in circulation and a RAP over 58,000, it's the entry point for anyone who wants Kleos exposure without chasing a nineteen-year-old tournament relic. It's also the item that actually shows up on the items leaderboard with meaningful volume, where Aphthiton effectively doesn't.

Why Are Coif of Glory and Coif of Excellence Still in the Catalog?

Two Kleos pieces never left regular rotation. Coif of Glory and Coif of Excellence are both perpetually on-sale, non-Limited items, which means Roblox mints new copies on demand rather than capping supply. They're part of the series' story and worth knowing about if you're building a full Kleos set, but they don't belong in a RAP or resale conversation because there's no scarcity to price. This is a useful distinction to keep straight across any older Roblox item line: catalog age alone doesn't make something a Limited, and only the capped-supply items carry resale value.

What Happened to Kleos Themis, Erebus, and Phoebus?

The other three members are retired event exclusives, off-sale and non-tradeable. Themis was a 250 Robux, 24-hour flash sale during Black Friday 2012. Erebus and Phoebus are far newer, both released in May 2024 as rewards tied to Roblox's Classic-themed event, earned through in-experience challenges rather than a straightforward catalog purchase. Phoebus was the seventh and final item added to the family. None of the three show up in resale data because none of them were ever flagged as tradeable Limiteds, which is a different fate from Themis's older Black-Friday siblings elsewhere on the platform that did eventually convert.

What Drives the Kleos Family's Premium?

Three things stack on each other here. First, the Dominus connection: sharing a creator and a design lineage with Roblox's most recognizable grail line lends Kleos borrowed prestige it wouldn't have on its own. Second, documented scarcity: the Aphthiton's award history is unusually well tracked for a nearly two-decade-old item, and traders put real weight on knowing exactly how few copies exist and where they came from. Third, the tournament pedigree itself. Most old-Roblox grails came from launch sales or holiday events; the Aphthiton came from beating other players in a competition, which gives it a different kind of story than a hat you could simply buy fast enough.

A Collector's Outlook

These two items serve very different roles in a portfolio. Phóteinos behaves like a normal mid-cap Classic Limited: liquid enough to enter and exit, priced close to what the market actually says it's worth. The Aphthiton is closer to a long-hold curiosity than a tradeable position; with roughly a dozen copies held by people who have shown no pattern of selling, actually acquiring one likely means negotiating a private trade rather than buying a live resale listing, and any price agreed there will diverge sharply from the RAP shown on the item page. This isn't financial advice, and thin markets like the Aphthiton's carry real execution risk even when the underlying demand is genuine. Traders tracking positions across old-Roblox grails can watch live listings move on the deal feed or manage active asks through the Reseller Terminal.

FAQ

What is the Kleos series?

Kleos is a line of seven gladiator-helmet items on Roblox released between 2007 and 2024: two always-on-sale regular items (Coif of Glory, Coif of Excellence), two tradeable Limiteds (The Kleos Aphthiton, Kleos Phóteinos), and three retired off-sale event exclusives (Kleos Themis, Kleos Erebus, Kleos Phoebus).

Why does the Kleos Aphthiton have no RAP?

RAP is calculated from actual resale transactions, and the Aphthiton rarely if ever changes hands on the open market. With roughly a dozen copies held by long-term owners, there isn't enough sales history for the formula to produce a number, even though trader consensus places its value in grail territory.

Is the Kleos series related to Dominus?

Yes. According to the Roblox Wiki on Fandom, both the Kleos and Dominus series were originally conceptualized by the same Roblox staffer, Shedletsky, working under the name Telamon.

Can you still buy any Kleos items today?

Coif of Glory and Coif of Excellence are both regular catalog items still purchasable at their dynamic price floor. The Kleos Aphthiton, Kleos Phóteinos, and the three off-sale pieces are not available through the standard catalog purchase flow.

Which Kleos item should a new collector target?

Kleos Phóteinos is the more realistic entry point: it has consistent trading volume and a RAP that reflects real market activity. The Kleos Aphthiton is closer to a long-term acquisition project than a purchase, given how rarely it trades. This isn't financial advice.
