Mercenary

The Mercenary is one of the playable characters in Risk of Rain 2.

How to Unlock
The Mercenary is unlocked upon completing the challenge "True Respite". (Obliterate yourself at the Obelisk.)

Tips

 * You should always hold your Primary skill down. Laser Sword combos are not interrupted by your non-Primary skills, sprinting, or jumping, allowing you to slash while using Whirlwind, Blinding Assault, and Eviscerate. A Laser Sword combo will, however, only start when you are not in the middle of using another skill.
 * Whirlwind when used on the ground dashes you forward, when used in the air it acts like a double jump. Use it in the air to stay airborne, but use it on the ground to be evasive as it covers more distance faster.
 * There is a short delay before attacking again after the third hit in the Laser Sword combo. Activating Whirlwind immediately after the hit connects can cancel this delay.
 * When fighting bosses, Mercenary can stay safely in the air above their heads for a very long time by chaining together Whirlwind->Eviscerate->Whirlwind along with laser sword attacks and double jumps.
 * Your Blinding Assault cooldown reset leaves just enough time to do 2x Laser Sword or Whirlwind + Laser Sword before you need to dash again. You have just enough time to Eviscerate between Blinding Assaults, if you do it immediately without any delay between dashes.
 * Your longest distance jump combo is Sprint-Jump-Whirlwind-Blinding Assault-Eviscerate-Double Jump-Whirlwind.[Verify]
 * Prior to Build ID #3731106, Eviscerating directly into the ground when airborne makes you take heavy fall damage.
 * Mercenary's health regeneration is noticeably higher than other survivors.
 * Some bosses allow you to stand on their heads and slash away at them.
 * Wax Quail applies for Mercenary's first two jumps. Other survivors only get one jump to use Wax Quail.
