Milvus (Boost Raptor) is a 5 stars Assault character in Artery Gear.

Milvus is a strong molten cleaver due to her having 2 AoE skills. Her second skill is where it shines the most, especially in PvE. Since the attack always has elemental advantage, she can fodder farm in most maps without worrying about miss attacks. It also resets its cooldown when she kills something, allowing her to use it for quickly farming fodder. Do keep in mind she requires good gear to easily cleave though.

Her skill 3 is also super useful in lower enemy defenses and potentially stun them. In PvP, this can be clutch as some enemies will lose a turn, which is vital in securing victory, especially in higher ranks where the enemies are tanky.

She can also be used in hunts such as Octopus and Iron Maiden, where she can apply the defense break to increase your team's damage. Unfortunately, the defense break chance maxed is only 85%, so it isn't always reliable.  However, you can't really go wrong building her as your primary fodder farmer if you are lucky enough to pull her.
