How do I unlock Survivor?
You will see a meter below your health bar. This will meter will deplete and, once depleted, will regen health. You will have to get below 10% of your champions health (Champion's Max Health * .1) and not take any damage for a while to regen. You must restore all of your health for this to count.
You can view your progress under Profile >Awards
What Champions are good for this?
Any Champion can earn this and, if you're planning on playing this for a long time, this should come naturally, but naturally, some champions are better to disengage than others.
Pip - Solo/Fastest Method
Pip can inflict self-damage, so simply point the weapon to your feet and shoot until your health is lower than 10%.
Blink travels short distances which can allow you to get around corner good, but the real reason she's good at escaping is Soar. Soar allows Evie to not only move quickly, but to fly as well.
She has Smoke Screen which gives her Stealth for 3 seconds if she enters it. Her ability Hidden also gives her Stealth for 3.5 seconds. Along with the invisibility, she gains a 25% movement increase. Enemies close to a stealthed Skye can see her.
Hustle allows you to run for an unlimited amount of time at 65% of your regular speed, but you're still grounded, so you may get hit by a stray bomb.
I don't see anything on my award screen.
The award screen seems to be broken right now. Once you play a game the award screen will break. If you see a broken awards screen, simply quit out of Paladins and launch it again.
