Thaviks, the Depraved

Thaviks, the Depraved is a Fallen Ultra Marauder that serves as the main boss of the Exodus Crash Strike, leading a gang of the House of Dusk Fallen in salvaging the crashed Exodus Black of its Golden Age machinery, endangering its AI Failsafe.

Gameplay
Thaviks is a difficult foe to pin down due to their erratic speed and stealth tech. For the first half of the fight, they pack a Shrapnel Launcher for ranged combat and will employ a moderate damage melee attack when faced up close. They will also preserve the Overcharge left by Overcharge Shanks that appear throughout the fight, limiting the playing area. Every time their health is reduced by 10%, they will place a smoke bomb beneath them, causing them to vanish. They will only teleport back in when all the adds are cleared.

When their health reaches 50%, they will switch from a Shrapnel Launcher to a pair of Shock Blades, making them more aggressive when pursuing Guardians. They will remain with these bladed weapons until they are killed. While they do have a ton of health, if you can spot them before they teleport, you can get some good hits in before they attack.

Trivia

 * When Thaviks turns invisible, they do not disappear from the game. They may teleport from side to side (where the overcharge shanks spawn). There used to be an exploit where sharp-eyed players could see them crawling on the walls of the room and could shoot them into a death-fall, drastically shortening the battle.
 * Thaviks appears to have robotic legs, the reason for why they were removed or torn off is unclear.
 * A possible reason for Thaviks having robotic legs is to help them navigate through their boss room, when it is covered in Arc energy from the Overcharged Shanks, as within their legs, is shown to have electricity coursing through them.
