Ranged

"Defeat enemies with ranged weapons to level this skill."

The pay-off at the low end is Snare at level 12 (15 Astral, 10 Nature), which roots a target in place. Pair it with weak-spot shooting, where crits have no cooldown, and ranged becomes the cleanest way to handle anything that would otherwise close the distance and out-trade you.

Top of the tree is the Magic Longbow at power 8 (118 damage) or the Magic Shortbow at power 8 (78) if you want the faster draw. Neither reaches power 9, because the only power 9 weapon in the game is the melee Dragon Scimitar.

Ranged armour is the set to pair with it: stealth speed at one piece, cheaper ranged attacks at two, and +25% weak point damage at three, which compounds directly with how the style already wants to be played.
