You get two headshots from thorn but the enemy is out of sight? Sit down. It stops the DOT effect and you will be fine. I didn't want to share this but with everyone whining about how OP thorn is, you folks need it. Sidenote: after you stop the DOT, you will be susceptible to another DOT immediately. Just a tip, don't forget to let your health regenerate before you go back into battle. Edit: sitting down will also avoid axion bolt. It will just buzz around your head.

Thank you for your contribution, I did not realize this with my 450k+ medal score. Edit: I thought common sense was more common. For the people replying you'll be an open target if you just sit down, [b]don't -blam!-ing sit out in the open[/b]
