Manic

Dashing in for quick strikes before falling back to the shadows the Grineer Manic is difficult to catch, and deadly to ignore.

Tactics
As its description implies, the Manic is a fast-striking and elusive melee unit. They can teleport across short distances and feature resistance to certain Warframe status effects that deal knockdown, though certain powers like Shooting Gallery can still stun them.

Manics will cloak for periods of time to close distance across open ground. They seem to move faster while cloaked, and cloaking completely regenerates the Manic's health. Manics will often cloak when being attacked to avoid death.

Manic AIs are survival- and stealth-attack oriented and can be very difficult to defeat in large rooms. Lure them into corridors for an easier fight; they cannot travel through doors without opening them, betraying their presence.

Manics will often announce their presence through loud, howling laughter.

Trivia

 * The Manic is the first of the winning entries from the Enemies Of The Tenno Contest to be implemented, designed by player Kadabura.
