Ramux is live, and the patch is aimed squarely at endgame pressure points
Throne and Liberty update 4.5.0 brings its new Archboss Ramux online after scheduled downtime beginning July 29 at 10:30 p.m. PT, with NCSoft and Amazon Games estimating roughly three and a half hours of maintenance in the official patch notes. The headline addition is the Ramux Archboss encounter, but the same update also widens the endgame menu with new dimensional trials, level 60 guild raids, new Archboss weapon recipes, and progression cost reductions.
For returning MMO players, the tension in this Throne and Liberty patch is clear: Ramux is a marquee boss with new item level 85 rewards, yet the update also acknowledges that the climb into endgame has been expensive and friction-heavy. MMOHuts, citing the official patch notes, reports that Equipment Growth costs are being reduced and that Inheritance costs are being cut by 50%. That makes this patch less of a single-boss drop and more of a recalibration of the late-game loop: fight bigger bosses, chase stronger weapons, and spend less to move builds forward.
The official update confirms that Peace and Guild-type events for the Ramux Archboss have been added, and that the Archboss schedule now includes Tuesdays and Fridays at 7:00 p.m. and 10:00 p.m. That schedule matters because Archboss content in Throne and Liberty is bound to competition, coordination, and timing. Players coming back for Ramux should treat the patch as an appointment-based endgame update rather than a solo checklist.
The Ramux Archboss fight starts with Atirat, then turns into a duel with the dragon knight
NCSoft and Amazon Games described Ramux in the July 23 Resistance Report as Throne and Liberty’s first two-phased Archboss. The setup is built around Ramux riding her dragon Atirat into battle, which the studio framed as a larger-scale encounter than previous Archboss fights.
MMOS.com, citing the official announcement, places the fight in Cavern of Eternal Void: Primorad in the Stillreach region and identifies Ramux as “The Last Dragon Knight Consumed By Hatred.” The same report says her lore is tied to the Arkeum League and revenge against humankind, with Ramux and Atirat sealed together before their return. That framing gives the encounter a useful read for lore-minded players: Atirat is not a decorative mount, but the first problem the raid has to solve.
The confirmed structure is straightforward but mechanically important. MMOS.com reports that phase one has Ramux mounted on Atirat while blue dragonflame hits the battlefield, with players needing to focus damage on the dragon. MMOHuts adds, based on the patch notes, that a ballista is part of the encounter. Once Atirat is brought down, Ramux absorbs the dragon’s energy and the fight continues against her directly.
That two-target sequence changes how guilds should prepare. Groups used to opening with fixed burn windows will need to account for an airborne dragon phase, battlefield pressure, and whatever positioning the ballista demands. The sources do not provide a full mechanic-by-mechanic raid guide, so players should avoid assuming that a standard Archboss damage race will be enough on day one. What is confirmed is the larger shape: kill Atirat first, survive the transition, then finish Ramux after she draws in the dragon’s power.
Ramux Archboss weapons are fixed at item level 85, with recipes split by material type
The official update lists the new Ramux rewards as Archboss weapons with item level fixed at 85. That fixed level is the cleanest confirmed signal that Ramux is meant to feed serious endgame progression rather than cosmetic collection alone.
Several weapon entries in the official patch notes show how aggressively these rewards lean into build identity. Last Dragon’s Thunder Greatsword comes with Strength 17, Dexterity 13, Heavy Attack Damage +11.5%, and Melee Heavy Attack Chance 210. Its Dragon’s Counterattack weapon skill can apply Weaken: Provoke through Valiant Brawl or Slash Wave, then grants the attacker a chance to deal counter damage when hit by a taunted target within 15 meters. The same skill boosts Valiant Brawl, Cruel Smite, and Slash Wave damage by 35% while increasing their cooldowns by 3 seconds.
For defensive melee setups, Scale Lord’s Massacre Sword is listed with Fortitude 17, Wisdom 12, Damage Reduction 69, and Hit Chance 230. Its Wall of Bitter Cold changes Stalwart Bastion, reduces that cooldown by 30%, and punishes attackers within range with Base Damage scaling while also carrying a chance to apply a movement-slowing Frost weaken effect. The official notes also list Last Dragon’s Thunder Daggers, Reverse Scale Tracker’s Judgment Crossbows, and Reverse Scale Destroyer’s Execution Bow, each pushing a different damage profile through critical, range, cone, back attack, or Frost-themed skill changes.
The crafting economy around Ramux Archboss weapons is just as important as the stat lines. MMOHuts reports that Thundercloud Scales are used for 10 of the new Archboss weapon recipes, while Skill Cores are used for another 10. The same report says Skill Core-based recipes will not have a chance to roll Potential Abilities. That is the detail returning players should read twice before spending scarce materials. A recipe may get you into the new weapon family, but the path you choose can affect whether Potential Abilities are in play.
There is also a delay to keep in mind. The official 4.5.0 notes state that a crafting recipe to upgrade Talandre Ascended Archboss weapons into Snowsoul weapons will not arrive during the July 29 maintenance and is instead planned for August 26 with update 4.9.0. MMOHuts frames this as a wait for players holding Ascended Talandre Archboss weapons. In practical terms, Ramux begins the new chase now, while one expected upgrade route has been pushed into the next major scheduled update.
Dimensional trials and guild raids give returning players more than one endgame lane
Ramux will draw the most attention, but update 4.5.0 also adds new Dimensional Trials and Guild Raids, according to the official patch notes. MMOHuts identifies Stone Grave Cradle as the new addition to Dimensional Trials and names the new level 60 Guild Raids as Thuban and Porfos.
That spread is useful because Throne and Liberty’s endgame serves different kinds of players at different levels of organization. Archboss windows demand attendance and coordination at specific times. Dimensional Trials are a cleaner fit for players who want repeatable challenge content without waiting for the next Archboss spawn. Guild Raids sit between those poles, giving organized groups fresh targets without requiring the same open-world timing pressure.
MassivelyOP also reported that the patch adds Archboss Ramux alongside new dimensional trials and guild raids, reinforcing that this is a broad PvE content update rather than a single encounter drop. The sources do not provide detailed mechanics for Stone Grave Cradle, Thuban, or Porfos in the supplied material, so there is no confirmed basis yet for recommending specific resistance sets, weapon pairings, or boss strategies. The safe preparation path is to treat the patch as a reason to audit your main build, your guild availability, and your material stockpile before committing to a new weapon craft.
Ascended Archboss Grand Assault returns with heavier spawn density
The patch also brings back Ascended Archboss Grand Assault for a limited run. MMOHuts reports that it returns for two weeks with double Archboss spawns, described as four per spawn. For players who left during a content lull, that detail may be as relevant as Ramux itself because it compresses more high-end boss opportunities into a short window.
That event structure creates a different kind of pressure than the new Ramux fight. A two-week return encourages players to log in now if they need Archboss materials, weapon progress, or guild activity. At the same time, the arrival of Ramux weapons and the delayed Snowsoul upgrade recipe complicate spending decisions. If you are chasing immediate power, the doubled spawn window may be worth prioritizing. If you are sitting on Ascended Talandre Archboss weapons and waiting for the August 26 recipe, the better move may be to gather materials while resisting expensive half-measures.
This is where the patch’s systems design gets interesting. New weapons create desire. Double spawns create urgency. Cost reductions lower the penalty for progression. But the delayed upgrade route means some players should still hold back until the 4.9.0 crafting picture is complete.
Cost reductions and Resonance changes make experimentation less punishing
The strongest quality-of-life change in the supplied patch coverage is the reduction to progression costs. MMOHuts reports that Equipment Growth costs are being reduced and specifically calls out a 50% cut to Inheritance costs. For returning players, that directly affects the pain of moving investment between pieces of gear, which has been one of the recurring frictions in gear-driven MMOs with frequent balance and loot updates.
The same report says Resonance enhancement is being changed so attempts will not result in a lower number than before. That is a meaningful protection against negative progression, especially in a patch that asks players to reconsider weapon choices around new Archboss drops. MMOHuts also reports that players who already spent on enhancement should receive a refund through in-game mail within 48 hours of the patch.
MMORPG.com reports that the update includes balance changes and more weapon enhancement cost reduction, with extra attention on Gauntlets because they are still the newest weapon type. The supplied sources do not include the full balance table, so it would be premature to declare winners and losers across every weapon pairing. The confirmed takeaway is narrower but useful: the patch lowers some costs, reduces one enhancement frustration, and continues tuning weapons as Ramux gear enters the ecosystem.
For build planners, that means this is a better patch for experimentation than a pure loot chase would have been. If you have been delaying a swap because Inheritance costs felt too steep, the 50% reduction changes the calculation. If your build depends on a new Ramux weapon skill, the absence of downward Resonance rolls lowers some of the risk around enhancement. The remaining risk is material choice, especially with Skill Core recipes reportedly lacking Potential Ability rolls.
A practical return plan for the Ramux patch
If you are coming back for the Throne and Liberty Ramux update, start with the calendar. The official patch notes list Ramux Archboss schedule additions on Tuesdays and Fridays at 7:00 p.m. and 10:00 p.m., and the update downtime began July 29 at 10:30 p.m. PT for an expected 3.5 hours. Ramux is the centerpiece, but the two-week Ascended Archboss Grand Assault return gives the patch a short-term farming window that should not be ignored.
Next, decide whether your priority is boss access, weapon crafting, or cheaper progression. Players in active guilds should look at Ramux and the new level 60 Guild Raids, Thuban and Porfos, first. Smaller groups or players rebuilding their routine may get steadier value from Stone Grave Cradle in Dimensional Trials while they prepare for Archboss timings. Anyone with expensive gear transitions pending should review the Equipment Growth, Inheritance, and Resonance changes before spending.
Finally, be careful with the Ramux Archboss weapons. The item level 85 rewards are confirmed in the official notes, and several listed skills point toward powerful, specialized build hooks. But MMOHuts reports a meaningful recipe split between Thundercloud Scales and Skill Cores, with Skill Core recipes lacking Potential Ability rolls. Meanwhile, the official notes say the Talandre Ascended Archboss to Snowsoul upgrade recipe is planned for August 26 rather than this patch. The smartest return is patient: clear the new content, collect materials, watch how the Ramux weapons perform in real fights, and avoid locking your long-term build before the delayed upgrade path arrives.
