The first 6 star SMG, and oh boy, she deserves it. As long as the damage isn't so overwhelming that it can kill her dummies outright, she has a chance to negate the damage. The chances increase if the enemy has more debuffs or has Marks of Vengeance on them, which immediately makes her a good pair with M4. Also the Sop doll is cute and comes with weird features. This is literally Sop's fault.

It's time to mix drinks and change formations. As a bartender, one might wonder exactly WHAT Jill can possibly do on a battlefield, and I'm sure she's asking the same thing.

Jill has a lot of firsts. She's the first unit in the game a player can use that doesn't shoot at all. She's the first one to have 8 different unique gears, and she's the first one to have a skill whose effects vary based on equipment. She's also the first one to have such an annoyingly complicated skill. The skill is everything. Her tile buffs are great, but they HAVE to be, because she doesn't contribute damage on her own. What her FP stat does is make her skill CD go down faster (except initial. Also caps at 30%, but this is INDEPENDENT of the reduction from rifle tilebuffs so yes, THOSE stack. Multiplicatively.). Unfortunately this means while she's good, how good she is depends almost entirely on how much you can use her ability to mix drinks, which btw, she can't do properly until lvl80.

Drinks are discussed in more detail in the detail page, because this is gonna be a long one.
