The star of this 1.5 version is undoubtedly Merlin. Introduced alongside a PV, Merlin joins Britannia wielding three types of weapons: Grimoire (Ice/Attacker), Wand (Lightning/Attacker), and Staff (Fire/Buster).

Grimoire Merlin is an Ice-attribute attacker who applies the 'Ice Soul' effect to enemies to enhance her own Ice-attribute attacks. By applying Ice Soul via her common attack 'Spatial Freezing' or common skill 'Seeding of Frost (E)', she increases her Ice-attribute attack power and deals increased damage to enemies afflicted with Ice Soul. Her special attack 'Cold Intellect (Q)' deals damage and enhances her common attacks for a certain duration; these enhanced attacks apply a Freeze effect to enemies every few hits. Her ultimate skill 'Iceberg Descent (R)' deals heavy damage and increases critical hit damage for a set time.

Wand Merlin is a Lightning-attribute attacker who uses combination skills to enhance her Lightning-attribute damage, focusing on her common skill 'Thunder Judgment (E)'. When a team hero activates a combination skill, her Lightning-attribute damage increases for a set time, and while this buff is active, using common skills applies a Vulnerability effect to enemies. Her special attack 'Electromagnetic Field (Q)' creates an area that attacks enemies. Each time the area hits an enemy, the cooldown of her common skills is reduced and their damage is increased. 'Thunder Judgment (E)' deals heavy damage, and using it twice within a certain time allows for the use of the enhanced 'Divine Judgment (E)'. Her ultimate skill 'Plasma Dome: Overload (R)' deals powerful Lightning-attribute damage.

Staff Merlin is a Fire-attribute buster who uses clones to reliably trigger bursts. Her special attack 'Illusionary Hit (Q)' summons a clone that taunts enemies for a set time and reduces their Fire burst resistance. Her common skill 'Seeking Crimson (E)' summons an orb that tracks enemies for a set time. Each time the orb hits an enemy, it reduces their Fire-attribute resistance and grants Fire burst gauge. Activating Fire burst allows her to trigger a ultimate skill that does not consume Mana Points when using special attacks or common skills. Her ultimate skill 'Celestial Collapse (R)' deals damage, and attacking enemies with an active Fire burst increases Fire weakness damage for the duration of the burst.

Additionally, exclusive costumes for Merlin will be added. Opportunities to obtain Merlin's exclusive Grimoire, 'Divine Treasure: Morning Star Ardan', and various rewards will be provided through an exclusive costume draw.

The main story expands to Act 14, 'Trap of Time'. The secrets of 'Taranis' are revealed at the end of the desert ruins, guided by clues from the Boar Hat tavern.

The new region 'Bound Sanctuary' is also being added. Previously blocked by sandstorms, this area opens after the 1.5 update and is a place where mysterious ruins and the evil energy of Taranis are sealed. Players can obtain 7 new materials, including Fox Bone Fragments, Fox Fur, Lizard Eggs, Ink Mushrooms, Dates, Malachite Ore, and Wasteland Amber. Notably, Wasteland Amber is a crucial item for Merlin's mastery.

Zones 5 and 6 of the Crossroads of Time Zones are now open. Fraudrin appears as the boss in Zone 5, and Diane in Zone 6. Fraudrin's weak attributes are Fire and Wind, while Diane's are Lightning and Ice. Clearing these zones rewards players with Star Fragments and useful materials.

New bound gear for 6 heroes has been added: Matrona's Longsword, Escanor's Sword and Shield, Clotho's Grimoire, Jericho's Rapier, Dreyfus' Lance, and Hendrickson's Lance. These can be crafted using the new 'Fierce Watcher' set materials.

Two new armor sets are added. The 'Fierce Watcher' set is the aforementioned material for bound gear, and the 'Greed Ruler' set is also introduced. Set effects consist of Critical Rate (3-set), Critical Damage (5-set), and Defense Shred (7-set), with quality ranging from 120 to 130.

Hell and Abyss difficulties are added to the boss challenge 'Eroded Guardian Golem'. Its weak attributes are Fire and Dark. Clearing the Abyss difficulty rewards players with Fierce Watcher armor.

The first raid dungeon, 'Taranis' Sanctuary', which offers rewards twice a week, is introduced. Its weak attributes are Fire and Wind. Defeating the boss grants the 'Greed Ruler' armor set, 500 Star Fragments, and Mystic Tokens. Mystic Tokens can be exchanged at the exchange center for 3 types of common weapon costumes.

Crafting for SSR Magic Crystal Shards has been added. Players can now exchange 15 SR Magic Crystal Shards for 1 SSR Magic Crystal Shard, easing the difficulty of weapon breakthroughs.

Additionally, 50 Charged Magic Cores can be used to craft the Fierce Watcher armor set, and specialty crafting allows players to turn 5 Malachite Ores into Malachite, and fuse Malachite with 2 Platinum Ingots to create Malachite Alloy.

One of the core changes in this update is the ability to wear bound gear and set armor simultaneously. Previously, bound gear replaced armor slots, making it difficult to utilize 7-set effects. After the revamp, players can benefit from both the passive effects of bound gear and armor set effects, with additional stat increases from wearing standard armor sets.

Equipment balance adjustments are also underway. Some armor set effects that could cause excessive synergy when combined with bound gear passives are being adjusted, though the bound gear passive effects themselves remain unchanged. The maximum quality for crafted armor and accessories has been increased, allowing for quality up to 125 through crafting. The Soul Eater weapon series also receives additional sub-options per weapon, improving their performance.

Existing dungeons, Ferzen Mine and Deep Spider Cave, are temporarily removed for renewal and will return later as new raid types. The City of the Dead is being repurposed as an elite reward farming content.

Rewards previously obtained from dungeons have been moved to boss challenges, allowing players to collect them all at once from bosses like Orgott the Eroded Warden, Galand of Truth, and the Eroded Ancient Dragon. Since dungeon rewards are added separately while maintaining existing boss challenge rewards, the total amount of rewards obtainable through boss challenges is increased. Crafting recipes that used dungeon materials will also be updated to use boss challenge materials.

There are also significant quality-of-life improvements. Using 2x Cube Keys now yields 2x rewards, and the Cube Key consumption previously required to claim rewards after defeating elite bosses has been removed. Additionally, a new hidden pet, 'Fluffy Snow Moth', has been added; its acquisition method is also hidden and must be discovered after the update.

Daisy returns with a pickup re-run. Daisy is a beloved hero known for her versatile support performance regardless of attributes and her excellent adventure skill convenience, such as reducing ingot material costs and expanding crafting queues. This is a chance for users who missed her at launch to obtain her.
