skill bonuses

do skills like atk up, agi up and booster extension add by a certain amount or by percentage? any one knows?

All I know is that there is no visible change.

for atk up and def up, for every point you put into them, u get 1 back. So putting 1 point into atk for FAZZ would be like putting 2 points. For Fortress, it would be 1:3.

but for skills like fortress, every stat in def pluses less right? and the bonus only activates when said skill activates?
then for booster extension? like zero says? by percentage?

that's only for oc with regarding for fortress. Regular points still 1:1 but for oc it would be 1:0.6 . Same thing with precision scope skill. For boost extension, it should just be a flat amount because there is no stats that can increase actual boost, only boost speed. You can see that if it was a %, then C rank with red boost would boost for the less time compared with A rank with red boost.

ic. cos recently i training a ball-k and was wondering what to stat it on

2 spd, 2 agi, oc atk.

i've been seeing people add their c points into boost recently, even when the suit ain't even a rock... before this, boost was neglected badly

could anyone explain? i mean, wouldn't it be better into atk or agi or even hp?

No, there is no stats that increase boost. Only thing in stats that comes close is boost speed.

err... yea, that's what i meant
