Promotion Classes

Ranged heavy pure damage, you can reduce enemy damage with barrage, and archers stake prevents movement reduction/root effects. You will gain suppression shot, and increased range (+9m), your rapid fire can expose punish targets.
Your passive revolves around standing still and spamming basic bow shots.
Warden
The talents lean towards full melee damage dealer builds, revolves around traps (major burning damage and debuffs – including anti stealth), you gain forest step (melee teleport to targets), and you can buff your group with damage bonuses.
You also reduce a lot of damage taken, both from your archers stake, and you’ll be able to wear mail with this promotion class.

You are now a stealth/melee damage dealer, you gain a stealth tray with the Ambush power. Your archers stake will instantly slow in a big field, and you’ll have an empowered cross slash to apply severe bleed to your target. You will also do increased damage behind targets.
Your passive is a buff stacking up damage for your next Dagger spin, stacking 10 times (max + 250% damage).
