Botzu's Quick Evaluation
+ Talent: Each hit has a chance to crit for additional damage that makes her randomly hit really hard
+ Great for early Challenge Modes since you need cheaper units and she deals more damage than the 4* Snipers at equal levels
- Says "Ko Ko Da Yo" every 15 seconds
Operator Overview
“Doctor, let's play a game~ Put an apple on your head and we'll start~”
Some Doctors disparage Kroos for her drawling voice and her repetitive “Ko~ko~da~yo” catchphrase (which roughly translates to “I’m here” or “Here I am”). However, many other Doctors swear by Kroos as a staple Sniper for the early- and mid-game of Arknights. A 3★ Anti-Air Sniper with surprising burst damage potential, Kroos can even pull her weight in difficult late-game stages, especially if you don’t have multiple higher-rarity Snipers who can replace her.
The trick is in how smoothly Kroos’s kit synergizes with itself. Her Talent, Targeting – Primary, has a random chance to increase the damage of her attacks (like a critical hit in other games). Meanwhile, her Double Tap – Auto Skill automatically triggers every few attacks and causes her to shoot two stronger arrows at once. With her naturally quick rate of fire and the constant extra shots from her Skill, Kroos activates her Talent quite frequently, punching through enemies at a terrifying rate. As a 3★ unit, her cheap DP cost and low investment cost are appealing bonuses, as well as being able to max Potential easily.
Of course, being a 3★ unit also means that Kroos cannot E2-promote, which puts a cap on how much she can grow to help the team. Promotion gives higher-rarity Operators access to more levels and additional Skills, giving them an advantage. On the other hand, many stages are easier if you deploy multiple Snipers, and while Kroos may fall behind over time, she’ll remain an excellent backup Sniper for much longer than you might expect. So look out, drones! “Ko~ko~da~yo!”

Within, Sniper Operators are this simulation's focus target.
Pains have been taken to assemble this simulation's team, and ample personnel are present, but lack direly for long-range output methods.
Focus area has been assigned to Operator Kroos. As her detachment's sole Sniper Operator, her composure and firing skills will determine what direction the simulation's outcome goes.
