Coming out from a smoke bomb, Eileen is the latest soul joining the human roster bringing a kit heavily focused on mana control and damage. Her main skill is her bread and butter, allowing her to get stealthed, increasing her critical rate and critical damage significantly while also putting enemies to sleep.
Stealth is a core mechanic of her kit - while she is hidden she can increase the damage of her 'Don't just stand there' skill and copy buffs(even if the description reads 'steal') using her Everything's mine! Passive. The buff stealing unfortunately affects only stealthed allies, but this at least includes herself and also enables more potential synergies in the future.
Speaking of synergy, her artifact buffs the attack and critical rate of stealthed souls and (at legendary+ or above) allows Eileen to enter stealth when using her 'Don't just stand there' sub skill as long as there are no enemies within 3 meters of the target. This makes gearing Eileen very easy, the usual dex/crit dmg set is great on her since she has a lot of free critical rate% when she has her stealth buff.
Her ultimate also has a similar gimmick, targetting the enemy with the lowest HP and also dealing splash damage around them. Her main target receives extra damage - and the bonus skyrockets when there are no allies close to the target.
We've talked about Eileen's damage potential, but what makes her interesting is her ability to control mana on the opponent: her ultimate skill will steal all the target's mana as long as she's hitting an enemy below 30% of mana, and her 'Don't just stand there' subskill will do the same as long as the enemy is below 20%.
This makes Eileen an excellent choice for players who want to improve their raid performance in Charite, where keeping the boss' mana in check is one of the most important mechanics of the fight, coupled with her increased damage when hitting an isolated target
Her kit will likely be a great addition to ESS teams as well, with her access to the rare sleep status, and bonuses to fighting an isolated target. Despite all her good points, Eileen is not a mandatory investment; while she opens up new team possibilities like running two human-centric teams, previous team options remain just as valid and successful in the current guild raids environment.
Since her ultimate needs to be cast at the proper time in order to ensure she can steal mana, players that prefer using autobattle may not find her as useful. Also, outside of bosses, her assassin role can overlap with souls players may have already invested heavily into like Aki and Linzy, leading to diminishing returns for players that are still in the process of fleshing out their roster.
It is also important to note that, at the time of the review, Yuria was just released and the anniversary is already within sight - we suggest players be mindful of their resources and prepare for a potential new A/D soul for anniversary. Claudia should also get a rerun banner during anniversary, in case you missed out on her!
