In Arknights: Endfield, Kelsie, as a six-star operator, although categorized under the medical class, is far from being a simple healer in the traditional sense. As you will discover in Arknights: Endfield, Kelsie's abilities and her unique traits make her seem to possess infinite possibilities, capable of handling numerous complex and critical tasks with ease. Therefore, it's essential to understand her skills clearly.
Structural Reinforcement is Kelsie's first skill. Once activated, it instantly boosts her and her core talent's defense by 150%. At this point, her core talent seems to be infused with the power of steel, transforming into a shield. The character appears to be clad in heavy armor, with her defense value reaching around 637, and her physical resistance also reaches an efficient level of 50%, making her a true high-defense unit. This skill enhancement improves her survivability on the battlefield, allowing her to stand firm amidst a hail of bullets. So, if placed in the team, she should be used in the front line.

Tactical Coordination, as her second skill, can be considered one of Kelsie's ace skills. It's like accelerating into battle; the moment the skill is activated, her healing speed increases drastically by 100, essentially doubling her attack speed. Its primary effect is to significantly enhance her own survivability, giving her stronger endurance in harsh combat environments. More impressively, within just 20 seconds, it can block all fierce attacks from opponents while also boosting the core talent's attack by 50%. This skill not only elevates Kelsie's healing efficiency to a new level but also allows Mon3tr to successfully block other operators, providing more output space for allies.

Meltdown, as her third skill, can, upon activation, increase the core talent's defense by 300% for 15 seconds, while simultaneously boosting attack by 360% in an instant. Although the attack power will gradually decrease afterward, during this brief peak period, Kelsie can directly provide a powerful boost to other teammates. Currently, there are several ways for players to obtain Kelsie, such as participating in limited-time events, drawing from the pool, or using visitation tickets, without spending real money. For players who are willing to spend, they can simply purchase her from the store to get this powerful operator.

Kelsie has a high adaptability in both team battles and field exploration. Her protective skills can be applied to every teammate, and her efficient healing ability is quite commendable. With these traits, players can cleverly pair Kelsie based on the team's actual needs. Her strength has always been highly regarded among the player community, not only due to her strong healing capabilities as a six-star medical operator but also because of her unique summon, Mon3tr, and the diverse skill mechanisms. In practice, this can be used as a core strategy to complement other backline members.

This concludes the introduction to Kelsie in Arknights: Endfield. While her specific strengths and skill settings may vary slightly due to game evolution, based on her outstanding performance and deep background in the original work, it's reasonable to speculate that she will maintain a high level of strength in the new game, continuing her versatile role and becoming a reliable assistant for players on their new journey.
