Combat Discipline will increase its Damage and reduce its 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 its Chance to Hit indirectly by increasing a player's attack rating.
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 magic 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!). It will furthermore fire an unlimited amount of (invisible) projectiles at once, hitting every single target in range, even those behind walls. This is likely an unintended exploit.
