Battleborn

To Serve man- Hasten allies with Temporal Distortion 100 times
For this challenge you will need to choose the RT option when you are level 1. This will unlock the ability to hasten allies that are within your temporal distortion bubble (cast with LB). It appeared to only count for me when it was cast on other ally players and not minions, but it did count for each individual ally hastened and not just the number of times it was used. Just cast your distortion bubble over a group of your teammates and it should build up pretty quick

Searching…- Trigger bonus damage from Eins, Zwei, Die 250 times
Eins, Zwei, Drie bonus damage is triggered after you hit the third shot on a single target. You can keep track if bonus damage is triggered based on a circle that appears over the enemy’s head that fills in once bonus damage is triggered. This can be sped up by using the LT upgrade on level five which will trigger bonus damage after the second hit instead of the third.

Hobo Eradication Protocol- Deal 6,000 damage in a single match with Bindleblast, 10 times
Bindleblast is Marquis’ ultimate attack which unlocks at level 5. The attack is a precision shot that deals splash damage in the area around where it lands. The damage dealed by the shot increases based on the distance the shot travels before making contact. The best way to quickly rack up damage is to shoot your bindleblast into large groups of enemy minions. It is difficult to target enemy battleborn with the attack and it works best at dispatching groups of minions. You should hit 6,000 damage after 2-3 shots into groups of full health enemies at a good distance.

More Robot Rebellion- Deal 100,000 damage with predatory strike
Predatory strike is Marquis’ RB ability which launches an owl that can target and explode on enemies. It will take time to reach 100,000 damage so throw your owl into enemies whenever the cooldown ends. Best skills to increase damage output are level 1 LT, level 2 LT, level 8 LT, and the mutation that allows for two owls to be on the field at the same time.

Overprotective- Play 5 matches on the same team as Pheobe
This is pure luck, but Pheobe is a pretty popular character so it shouldn’t be too hard to find matches with her. If you see one of your teammates playing as her make sure to switch to Marquis.
