Introduction to the Y瑟 instance strategy and a comprehensive look at tips for clearing the instance. Note: There seems to be a character encoding issue with "Y瑟". If it should be "Ysera" or another name, please provide the correct term.

For this new title, the highly attractive gameplay has already been introduced to everyone before. Many players want to know about the introduction of the Iser raid strategy because the difficulty of early-stage raids is relatively low. As long as everyone's level meets the requirements, it's not difficult to clear them. However, in the mid-to-late stages, the high-difficulty raids encountered by many players can be overwhelming. Below, we will introduce several typical raid strategies.

First is the Sharron raid; this raid is a stumbling block for many players. Many have faced setbacks here. Sharron’s casting speed is very fast, not only in her normal attacks but also in skill releases. Her skills also have a haste effect, significantly reducing cooldown times. Additionally, Sharron's damage skills come with DOT (Damage Over Time) effects, which can easily cripple players if defenses are insufficient. More challenging is that every time the party takes DOT damage, her subsequent attacks become stronger, compounded by stacking effects.

When dealing with Sharron, it is essential to have characters in your team who can cleanse or be immune to DOT effects. Otherwise, once Sharron’s damage starts stacking, you will face immense pressure. The team should also have high DOT resistance to reduce raid difficulty and include characters that can counter haste effects to slow down the boss’s attack speed. Besides these support roles, the remaining positions should primarily consist of DPS (damage per second) characters since Sharron demands high output. The longer the fight drags on, the higher her combat power becomes. If your team composition meets these conditions, the difficulty of defeating Sharron will be significantly reduced.

Next is the Astarte raid. This boss is jokingly referred to by players as one of the most straightforward bosses. In high-difficulty mode, her damage is extremely high. Once dragged into a prolonged battle, victory becomes nearly impossible. Astarte’s attacks can ignore defense, causing significant damage. Additionally, every four actions by same-attribute characters increase the damage taken by 20%. Therefore, the more turns pass, the less advantageous it becomes for players. If her skills hit an attribute she counters, her action speed increases by 20%, so your team should not include attributes she counters.

Astarte is essentially a pure DPS (damage per second) challenge. Without sufficient output, clearing this raid is difficult. If your team lacks enough damage, consider using a poison team, as poison attacks deal fixed 5% true damage in Iser. As long as the enemy isn’t immune to poison, a poison team can be very effective. We recommend using the combination of Seon-ya, Fergus, and Ophelia, which performs well against Astarte. With sufficient training, this raid won’t pose much of a problem.

Finally, there is the Whitney raid. This boss is also a tough opponent among high-difficulty bosses. She first casts a skill that reduces the defense of party members by 60%. If minions attack at this point, players may be instantly killed. Therefore, a character capable of cleansing debuffs is necessary. For each debuff on the boss, her attack speed decreases by 3%, but attacking the boss can reduce the number of debuff stacks. So faster attack speed is better for handling this skill. Notably, every three turns, she revives minions. At this time, focus mainly on the boss rather than the minions.

The introduction of Iser raid strategies ends here. These bosses mentioned above are currently some of the most challenging for players, each with unique abilities and characteristics. If you want to challenge them, you can follow the tips outlined above.
