Combat Discipline will increase it's Damage and reduce it's regeneration time if this Combat Art is placed within a combo. This increase in Damage is direct, it increases the +xx% that the CA adds to base damage.
Speed Lore will increase it's Chance to Hit indirectly by increasing your attack rating.
Specific Weapon Lores will also add to chance to hit indirectly.
Capricious Hunter Focus will directly decrease regeneration times, as well as increase the maximum level of the CA that you can use.
Main killing Combat Art for a ranged dryad
Rotate is an extremely good mod to take. It makes the attack turn into a basically 360 degree Area of Effect.
BUG: On the console version, Darting Assault does not take into account the intelligence boost from Acute Mind if wielding a staff. The display will say that this is the case, but tested in game numbers prove it other wise.
Pros and Cons
Very strong Area of Effect attack
Works very well with ranged weapons
In the Ice and Blood expansion, taking Magic Staffs as a skill will make the range on this Combat Art extremely far (off screen!)
Looks great when working with Life Leech or Regen per Hit gear!
Not very effective using melee weapons
Until the gold mod for Rotate is taken, the attack only fire in front of the dryad.
