Finally, she is done true justice, and has an excellent MOD that aims to enhance her original capabilities massively.
Kar’s upgrade is all about taking her original Skill, Chain Shot, to the next level. The upgraded Skill 1 now has the ability to crit and targets the enemy she last attacked, already quite nice. Her new Skill 2,
Crown of Shackles, places an additional Accuracy check onto her Skill 1, dealing double damage if it succeeds. No bells and whistles, just a 100% additional damage on a typically high success rate. On top of this, she gets a medal with each victory up to 4 times, which permanently increases her initial number of Skill 1 stacks for the rest of the battle.
Needless to say, Kar’s nuke damage potential simply skyrockets with this upgrade. Her raw damage per Chain Shot is immense and will make short work of even the hardiest enemies. Imagine Carcano M91/38, except working on everyone. Grape is still preferable in most fights where she can function, but in any other case, Kar is the girl for the job. Since nuking is highly useful, Kar stands proud as an extremely desirable upgrade that everyone should aim to do. Taking her all the way to
MOD3 is recommended as her unique cape replacement has a whopping extra 23% Crit Damage over a normal cape, and even does away with the movement penalty.
