Melania

Melania is a unique Damage Dealer whose main mechanic revolves around stealing Moxie from enemies, and building up her own ultimate's power. This gives her two possible roles in a team; The first one, for those who don't want to or can't invest much on her, consists on focusing on shutting down enemies. This role works as a Sub-DPS and is better suited for short battles and the Early Game, since Melania takes quite a few rounds to build up her stacks and unleash her full power. 

The second role, and the one she's been designed for, is focused on Burst DMG. Although she may seem to lag a bit behind her peers of similar role and rarity at first, that's merely a facade. True to her lore and character, Melania is all about careful planning and building up before hitting her target with overwhelming might. 

Her first skill, “Silent Takedown” can literally steal Moxie from the target. This is her main tool to shut down enemies while gaining extra Moxie for herself. This allows Melania to use her Ultimate almost back to back. Most of the time, however, players will likely only have access to this skill at level 2, which is already good enough to fulfill its role regardless if Melania is the main damage dealer of the team or not. 

The second skill, “Clockwork Rats”, has a fixed leech rate of +20%, and can go up to +50% if under [Thief Master] status. At three stars, this mass attack skill has a base multiplier of 300%, and under [Thief Master] it also gives +1 Moxie to the caster. Under these ideal conditions, 300% multiplier with 50% leech rate is the same as Eternity's ultimate, the difference here being, “Clockwork Rats” is a skill that you can spam more easily and Melania doesn't sacrifice her own HP to attack. 

Last but not least, the Great Thief's ultimate takes three uses to reach its maximum stacks if Melania is at i3. That can take an average of 7 to 9 rounds, making her better suited for longer battles, those becoming more common later in the game's lifecycle as Limbo and UTTU become more complex and new endgame modes are added. At P0, “Ridiculous Eyewitness Testimony” has a base of 650% Mental DMG that can be amped up to 722% with the 72% bonus of [Fixed Plan] at full stacks. Needless to say, this squirrel with glasses can hit like a truck, especially if paired with someone who can buff her damage or crit.
