punish ray buff gone

i don't know why but my punish ray buff gone when i use this combo

assault (opener) - still there count (2)
decoy (save) - still there count (1)
buster lance (cons) - back up to (3)
chronos (swift) - gone

but it works fine with this combo

assault (opener) - still there count (2)
kairiki (save) - still there count (1)
buster lance (cons) - back up to (3)
chronos (swift) - still there count (2)

or with

assault (opener) - still there count (2)
chronos (save) - still there count (1)
buster lance (cons) - back up to (3)
assassin stab (swift) - still there count (2)


is it because of decoy??

 

Decoy spend the stcks of Punish Ray like a Skill.

 

it seems that if i have decoy in the combo AND put chronos at the end of the combo, the buff disappears. might test again later

 

I think the bonus hits from chronos drive are the problem. The bonus strikes have a separate damage calculation for each hit so they might consume a punish ray stack individually. Though all hits should have the same critical calculation.. Sadly I don‘t have a halberd build with punish ray right now to testify.

 

Ok so i've tested
X > chronos > buster lance > X ===== buff stays
X > X > buster lance > chronos ===== buff stays
X > decoy > buster lance > X ===== buff gone
X > X > buster lance > decoy ===== buff stays

And with both skill there
X > decoy > buster lance > chronos ===== buff gone
X > chronos > buster lance > decoy ===== buff stays

So in conclusion, decoy is the problem. Can work around this by using decoy at the end of the combo. If I use decoy in the mid of the combo, the buff disappears.

 

Each hit from decoy spend 1 stck of Punish Ray.

 

Weird thing is, if I put decoy at end of combo, punish buff won't disappear even when decoy vanish. So I'm guessing it spend stack every time hit only when combo still active.
