Clint Barton, Hawkeye

Whenever you cast a historic spell, Hawkeye deals 2 damage to any target.
"It doesn't matter what you did, or what you
were. If you go out there, you fight, and you
fight to kill. Stay in here, you're good, I'll send
your brother to come find you, but if you step out
that door, you are an Avenger."
