do abilities stack ?

[Mikasa Ackerman]

i currently have a weapon with double overdrive and double ap for tidus , if i put triple overdrive on the weapon , do the two stack and if yes how , will it be 5 times ( 2 +3 ) or 6 times ( 2*3 ) or will it just be the higher one ( 3)

I believe it will just be the higher one.

AFAIK this is how it works, yes.

Stacking only really works between different types of multipliers (that happen to have some synergy). So if you have Triple AP, Triple Overdrive, and Overdrive->AP on a weapon, you do effectively get multiplicative synergy - but Triple AP and Double AP will not multiply with each other, and neither will Triple Overdrive and Double Overdrive.

For stat boosts, I believe it's additive stacking - i.e. if you put +5% STR, +10% STR, and +20% STR on a weapon, you end up with +(5+10+20)=+35% STR, not +(5%*10%*20%)=+38.6%.
