Cut it short, I guess you want to know how much you need to spend to get 2 lines of ATT %.
Here is the truth
You need around 35 cubes ~ 225 additional cubes.
If you are unlucky you need more than 225 additional cubes
That's the truth I gotten 2 line of ATT % on my emblem, secondary weapon, weapon.
My emblem took like 500 bucks which is around 100 cubes at legendary?
My secondary weapon took 59 additional cubes to get 21% ATT at legendary.
59*4 = $236.
My weapon took 225 cubes to get to 21% ATT 12 % boss dmg which is 3 perfect prime lines.
To get a 3 perfect prime lines on those items you need at least $1000 sgd. You heard it, or around there which is 250 cubes to get 1 chance to get 3 perfect prime lines on your weapon, emblem or secondary weapon.
