Turret Engineer

Turret Engineer is a challenge located in the Titan Robot Production Plant. The challenge is achieved by destroying Felicity Rampant's legs without destroying any of her three turrets.

Strategy
There is only one caveat when completing this challenge: avoiding damage to Felicity Rampant's turrets. Avoid the use of any splash damage or any AoE weapons. If you're playing Nisha, and have points invested in her Trick Shot or The Unforgiven skills, then it is best to use weapons that cannot ricochet at all, such as channeled beam lasers, like Thorny ol' Rosie. Due to the nature of the majority of the vault hunter action abilities in the game, using abilities is not recommended. If possible, a continuous beam laser with corrosive damage and Piercing Rounds Luneshine is ideal for destroying the legs, as they are treated as an armored target with shields. Lastly, it's recommended to unequip any items that passively deal damage, such as spike shields, nova shields, and 3DD1.E, as they may accidentally be triggered and destroy a turret. Like most challenges, this is easiest to achieve by revisiting the area on normal or true vault hunter difficulty modes; however, even with a large level advantage, it may still be ideal to respec your character out of automatic recoil skill points, like Bitter Riposte, since such abilities can one-hit kill the turrets when fighting the boss from a significantly higher level.
