Dernière patch avant l'OBT ;)

Instance Matching System

In order to facilitate group play in the instanced dungeons, we've implemented the Instance Matching System. The IMS will pick players from a pool of cross-server characters to form groups to tackle the dungeons, helping to minimize wait times.

The following IMS rewards are being removed with our launch build, but are included in our Open Beta Test build.
Players who use the matching system and defeat the final boss of an instance receive a reward item, "Valkyon's Response I - IV," that may drop various consumables and a gem (which can be sold for gold) via the in-game mail system. Players who use the instance matching system also earn more tokens and get attack speed increase buffs.
For solos and duos: the party gets a 4% attack speed increase.
For trios: the party gets a 3% attack speed increase.
For quartets: the party gets a 2% attack speed increase.
Timing on the "dropout" debuff, applied when someone leaves a group after it forms, has changed to be immediate, rather than after the group has existed for 10 minutes. The dropout debuff applies only to the party leader when the party disbands. The dropout debuff is not applied to party members who are kicked out of the party.
The 50% reduction in dungeon reset time for players who use the matching system does not apply to Temple of Balder and Fane of Kaprima.
Reputation System/Daily Quests

With this system, the player performs quests to increase reputation with various factions to purchase exclusive items. Reputation levels are Hostile, Suspicious, Apprehensive, Wavering, Neutral, Favorable, Friendly, Trusted, Revered—viewable in the reputation information tab in the character information window.

Reputation levels limit which items a player can purchase from a faction. Reputation levels increase as the player performs daily quests offered by a faction and hunts certain monsters in an area.
Daily quests are available at the base town of each faction and are indicated with a green mark. The Agnitor faction provides quests as soon as the player enters a nexus area.
The six factions are as follows:
Invalesco: Enabled when player enters Val Tirkai. A Mysterium group dedicated to unlocking the secrets to defeating the argons in Val Tirkai.
Shariar: Enabled when player enters the Khanovar Front. A unit of irregular forces engaged in operations against the argons on the front line.
Valsekyr Hunt: Enabled when a player enters the province surrounding Kanstria (Val Kaeli). A loose fraternity of soldiers, mercenaries, and hunters who love big game and take the battle to the argons.
Hyderad Legacy: Enabled when a player attains level 60. This faction, centered Balder's Refuge are followers of the principles of Hyderad, who work to preserve the past and protect the environment.
Hands of Velika: Enabled when a player attains level 60. A secret coalition of merchants and soldiers who look after the city's best interests and act on its behalf.
Agnitor: Enabled when a player attains level 59. An elite team of scholars dedicated to unlocking the secrets behind the nexuses. The reputation store sells new mounts, grade 13 superior equipment, accessories, and consumables.
Players can perform up to 10 daily quests per day, with a maximum of 5 daily quests for each faction. The Agnitor faction offers a maximum of 2 daily quests per day, depending on the player's reputation level. The daily limit resets at 2:00 AM, server time.
Reputation stores offer items purchasable with gold and with accumulated credits. Items include green accessory crystals, materials for accessories, accessories, mounts, and various consumables.
Nexus

Six to eight nexuses randomly appear in the Khanovar Front, as well as the Argonea, and Granarkus regions of Val Kaeli. Each nexus has three stages with progressively stronger monsters. If players defeat all monsters at each stage, the nexus closes and the players receive reputation values and reputation points with the Agnitor faction (via the quests the players automatically received when they entered the nexus).

When a nexus closes, another one appears somewhere else in the region. Nexuses continue to appear in this way until the players close all of the six to eight nexuses, or until an hour after the first nexus is created. Each nexus gradually grows larger, making the ordinary monsters in the area disappear.
Players who enter a nexus randomly receive both a stacking buff and debuff, and both accumulate over time. They also are automatically offered a party through a matching system, and they receive "The Mysterious Nexus" quest (if the player is level 59 or higher). A player receives different versions of the quest at each stage of the nexus. Quests are complete when all monsters for that stage are defeated, but a player automatically fails the quest if the player does not perform any activities for a certain period of time after attacking a nexus monster.
Every monster in the nexus (other than the small monsters) drops a nexus-exclusive reward item called the "Nexus Boon." Anyone can loot this item; doing so gives a small amount of reputation points with the Agnitor.
Players receive an additional reward when they complete all automatically received quests from Stage 1 to Stage 3 of a nexus, and when they complete the three stages while 30 or more players have participated.
Currency

In-game currency has changed from gold into denominations of copper (equivalent to the pre-patch gold), silver (equal to 100 copper), and gold (equal to 100 silver).
Pegasus Travel

Players can travel directly from town to town without passing through a major city.
Trade Broker

A smart search function has been added, enabling searches for items with specific conditions or attributes. The search function is more detailed.
The maximum number of items you can sell at once is increased to 50.
When you register an item to sell, its minimum and average price are displayed in the price input UI.
Enchantment

A warning message appears if a player puts enchanted equipment into the space intended for the material equipment to prevent accidental reversals. The tooltip for the equipment appears immediately to further confirm that the player has selected the right item.
Achievements

Various achievements have been added for new game elements. New mounts, masks, and titles are offered as rewards for difficult achievements.
Rested Experience

The maximum rest bonus in level 1-33 zones has decreased. Higher levels zones have larger maximum rest bonuses.
