Last time I checked, only the element that would affect what you are fighting applies. If you had a water bow with a fire arrow and you were fighting metal stinger (earth), only the fire element would take effect since it's the only element that would affect it.

ASPD lowers the amount of time it takes for you to perform your attacks. 0-1100 ASPD lowers the amount of time it takes you to use your auto attacks, so at 1100 you will be able to attack as often as possible. After 1100, every additional 180 ASPD increases the animation speed of your attacks by 1% (auto attacks and skill attacks; support skills won't be affected). Your ASPD caps at 10100, which would give you 50% more motion speed. Extra motion speed is good for characters that have long combos.
