U-10

U-10 is the fourth and final mid-boss the player will encounter in Let It Die. She represents the M.I.L.K. Faction and will drop M.I.L.K. Faction Metals.

Lore
Mother Barbs has no information on U-10, aside from security footage of her boss arena.

Uncle Death Mail: M.I.L.K (reaching 31F) Dear Senpai,

Uh-huh, it's me again. Sorry to bother you! This place is like a group of high-rise buildings, huh? Yeah, it's another strange one.

The area between the 31st and 40th floor is known as "Gunkanyama's Area."

I've spotted another of those Wall Marks. This one has "M.I.L.K" written on it! Yeah, there's no mistaking it. I went and checked to be sure. Don't underestimate it, though, looks kinda macho.

Also... there's apparently this new Mid-Boss MEIJIN was talking about. He was muttering about how it never used to be there and some stuff I didn't really get.

Anyway, you know I'm backing you, man. Later!

The Last Mid-Boss (post-32F U-10) Dear Senpai,

Nice work with that Mid-Boss! That thing was weird, huh? I mean, what's with that tail? Now, according to rumors, that flabby Mid-boss and the rotting girl one got a romance going on, and somehow a child was born from the Bridging Mid-Boss. That child was that tailed Mid-Boss. Yeah, I have no idea what the hell that means either. Ha ha! Anyway, there are some weird things in the world.

Anyway, you defeated it, so kudos, Senpai. I'll keep rootin' for ya!

Strategy

 * U-10 can be safely punished when she performs her body slam, tail whip, and tail dig attack.
 * She resists all weapon damage types equally, so use whatever weapon you can hit her with with the highest damage per second.
 * Her tail end is her weak point.
 * You can only damage her by hitting her body or the tip of her tail.
 * After receiving significant damage, sometimes, she overheats and starts meandering slowly around the arena for a while. You can safely damage her during this movement.
 * You can use shrooms.

Attacks

 * She performs swift dive kicks. She usually starts the fight with this attack. She only does this attack when she is up in the air supported by her tail.
 * She tail slams by swinging her tail overhead and slamming into the ground in front of her. She only does this attack when her body standing on the ground.
 * She tail whips by swinging her tail to sweep a large area of the ground around her in a counterclockwise motion. She only does this attack when her body standing on the ground, and she pauses after this attack before performing another attack.
 * Her tail can dig into the ground when her body stands on the ground. In a few seconds afterwards, the tails burrows back up and her tail to sweep a small area of the ground around her tail in a counterclockwise motion. Her tail comes up around the area where you were when her tail digged into the ground, and her body is stationary throughout the attack.
 * She body slams into the ground by jumping up in the air and slamming into where you are, resulting in a small shockwave around her slam. She only does this attack when she is up in the air supported by her tail, and she pauses after this attack before performing another attack.
 * She fires a laser from her tail end. She aims the laser right where you are a second before she fires it. She only does this attack when she is up in the air supported by her tail.
