Musketeer Warframe concept - "d'Artagnan"

d'Artagnan, the Musketeer

Passives: Switch-hitter - d'Artagnan can instantly swap between weapons. Additionally, with no melee equipped, he can utilise his personal Rapier.

1st: Finessing Strikes - d'Artagnan unleashes a flurry of rapier thrusts, damaging in a short cone and marking up to three enemies. Enemies so marked drop special pickups that give a stacking 25% Evasion (maximum 75%) when they die. This buff decays by one stack every 7 seconds.

2nd: Cross Cuts - d'Artagnan makes three quick horizontal slashes in front of him, dealing damage and reducing enemy speed and damage output by 15% per hit. Marked enemies take double damage and doubled debuffs.

3rd: One for All/All for One - Pressing cycles between two modes, holding activates. In One for All, incoming damage to d'Artagnan is converted into energy supplied to nearby allies, and damage he deals is converted into a weak damage buff to them. In All for One, d'Artagnan regenerates health, increased by the number of nearby allies; allies who use abilities temporarily increase the amount of healing they provide, based on the energy they spent.

4th: Musketeer - d'Artagnan draws his musket, consuming energy each time he fires it. It has high damage but a long reload time, and has a combo system wherein consecutive shots without missing reduce reload time (resets after 20 seconds of not being fired), down to a minimum of 15%. Marked enemies take an additional 75% damage from the musket, and spread their mark to 3 nearby enemies if killed by it. Aiming increases damage by 5% per second spent aiming, to a maximum of 50%, but also increases the energy cost by the same.
