1. DH shoots from afar, using hunger arrow or impale
2. Boar, brooding passive, and sentry (aid station) regen give up to 3% HP life regen to a DH stacking over 100k HP
3. Battle scars heals for 60% HP, negating burst
4. Run back to sentry aid station for life regen when hurt.
I have no idea ATM how to beat this build, I tried bursting the DH down. But failed :<
