[quote=“KA101, post:4, topic:5229”]If you’ve tried Elf-a you might realize that they have a way of needing more healing than you might expect.
Sleep is free, first-aid isn’t.
And yeah, I’d like to hear what successes folks have had, too. I know a few categories didn’t get post-Threshold stuff in time for the feature-freeze, so Bird might not be a great one ATM.[/quote]
I had nano-healing bots before I even started to mutate. 
Also, tireless doesn’t mean NO sleep. I just had to sleep once every three or four days.
Note the past tense. I had an unfortunate accident when I tried to learn a skill from a NPC while driving my truck, thus crashing into a gas station and blowing up X(.
