Weapon multistat bonus

Player Questions Started Last reply 3 posts
I see that some weapons have set bonuses ie: focus / mana /acumin etc.

But how do the multi choice ones work ?..They say it has a chance to do 1 of 4 differant things.. do u equip and it changes bonus everytime !.

I have probably overlooked some obvious clue..
You add the appropriate crystal of the SA you desire and then it only has that one SA. To change it, you would have to remove the SA then add another crystal.

Which costs money . . . so pick your favorite
ah i see..ok thanks
