Another Million and We're Even - Participate in killing Ambra 5 times. Self explanatory. You dont have to kill her just getting an assist will be enough. Just play Vs Bots with other human players because PvP isnt as active as before and Ambra is quite often in bots lineup.

Helician Hellraisers - Play 3 matches on the same team as Galilea. Play with other players Vs Bots and from time to time someone will choose Galilea. Or if you want to get it done fast just ask your friend to select her and play Story mission The Renegade. At the start of mission you can both jump of clif to your suicide and it will still count as you played thru whole match.

Time Blurs in the Depths: Heal 800 health with a single Wellspring, 50 times. Wellspring is heal you activate with your right button. You do more heal the more stacks of osmosis you have, so just attack minions and other Battleborn with your main left click attack and that way you will fill up all your 3 stacks in no time. To make this challenge easier use Helix's lv3 Overflow and lv5 Extremophile mutation. And also you can use Gear that gives you more Heal power, and then heal players or minions that you see have less than half of their health left and you will do 800 + heals without too much problem.

Song of the Emula: Deal 3.000 damage with a single Emergence, 10 times. With this I had the most issues until I found quite easy and fast way to do it. For starters use Gear that gives you Skill damage, I used Ghalt's and Beatrix's gear you get when you do all the challenges for them. But if you dont have them just open loot packs you get by playing the game and if you get it use the gear that has Skill damage. Also its good to use gear that gives you shards every second, so you can activate your gear faster and put it to use. With all of my gear I had + 16 % in skill damage on the base one. Then you can do it in vs Bots, little tedious you aim at minion groups and you need to get one or more battleborn in range of skill damage to get 3k. But there is even easier way. Play story mission The Archive, play as you would until you get to Melka and 4 small guys spawn, the ones that carry information to The Sentry, mission goal is for you to protect them. But dont, and dont build and buildables. Then go to cave where Varelsi spawn from time to time, and go around that cave, soon the Thralls will start spawning, then the key is to hord them to one place and use Emergence. It will take few tries but good thing is small guys will die all the time cause they have no protection and are cannon fodder so you will have infinite time to farm that damage there.

The Lifeguards Have Given Up: Affect 5 players with a single Riptide, 25 times. I got all of them on PvE, vs Bots with other players. So PvP isnt needed. Here you will want to use your Riptide to Heal you allies. As Helix upgrades use: lvl1 Soothing Mist, lvl 9 Stagnat Pools. Then just stay back and use your Riptide any time you can. Key is to hit 4 of your allies with it and you also count just by using it. Sometimes when you hit Ambra's Sunspot, Ernest's Egg, Klesse's Shield recharge stations etc. it will also count as an allly. In one match I played, there were only 3 other players with me in small spot, and one was using Ambra and he put sunspots around us, I used riptide and got 6 to count for this challenge in one game. So game is a little buggy around this challenge, sometimes it will count this, other time it wount register even if you hit all other 4 of your allies with it. But just concentrate on it when you play, and use it as often as you can in places where your allies are in small space. Use gear that helps with skill cooldowns and Helix upgrade that shortens your cooldown time with every hit you get with your main attack on any enemy or enemy's buildable. Helix skill you want to use is called Go with the flow.
