Diablo – How do spirit generator damage modifiers stack in Diablo 3 ? Additively or multiplicatively

diablo-3diablo-3-monk

If my current spirit level is giving me, let's say, 200% damage bonus on my spirit generator thanks to my Shenlong set bonus, will depth diggers bump this up to 300% or double it to 400% ? What about damage increase that applies to all damage, such as the bonus you get from Shenlong when at max spirit ?

Picture from the game

As you can see from the picture, it clearly states that it is "additional" and not "multiplicatively".
