This is a build that i always use in AB and Scrimmage when i play Havan Politrin.
1: Burning Arrow (Elite. You can capture this from Admiral Chiggen in Marga Coast)
2: Screaming Shot (Switch for a interrupt like Savage Shot if you think you'll need it)
3: Apply Poison (Switch this for Barbed Arrows if you can manage the easy interupt. You need to switch Screaming Shot for a other skill if you want to use Barbed Arrows.)
4: Mending Touch
5: Throw Dirt (Switch for Dryder's Defenses if you think that you'll face many enemies that attack with elemental damage. You can also try Natural Stride, but i don't know this skill too well)
6: Whirling Defense
7: Troll Unguent
8: Healing Breeze (or some other heal)
Usage:
Use Apply Poison when you're closing in on a battle.
Then fire with Burning Arrow, and if the enemy is in your aggro zone (the white circle around your green dot) use Screaming Shot.
Use Mending Touch to remove conditions.
Use Throw Dirt (or Dryder's Defenses) and Whirling Defense to blind your enemy and block your enemy's attacks.
Use Troll Unguent when you need healing and when you think you're safe.
Use Healing Breeze (or a similar heal) for quick heal when you're not safe.
Equipment:
Just a bow, tough a Shortbow may work better because you can then play nicely around with Screaming Shot. Any armor is useful.
Hope this build works for you and that you have fun with it.
