Bounty Hunter

Hit opponents with Jinada or secure range creep last hits. The bonus damage does not work on denies.

Check frequently opponents' inventories for detection.

If you get dusted while in Shadow Walk, use any activatable item or Shuriken Toss to leave invisibility and your won't be slowed by dust.

Avoid running by spots that are typically sentried like pillars and active rune spots.

In mid to late game, play ahead of your teammates, track opponents, break smokes, collect runes, place deep wards and snipe couriers.

Use Jinada off cooldown on opponents hero or to secure range creep last hit.

Bounty Hunter tends to snipe couriers, so be mindful about that.

Don't make it easy for Bounty Hunter to steal your gold with Jinada hits. Step away or damage him heavily.

Pair observer wards with sentries to spot Bounty Hunter's movements.

Encourage your allies to carry detection on multiple heroes.

Avoid buying items that grant you invisibility because of Bounty Hunter's Track.

Consider buying one of many items that allow you to dispel Track.
