You would have to change each InstantAction into a periodic Action!! Like so:....
periodicAction
actionCountType "Infinite"
actionIntervalTime
Level:0 2.000000
Level:1 2.000000
Level:2 2.000000
buffInstantActionType "ApplyBuffToSelf"
instantActionTriggerType "OnChance"
buffApplyChance
Level:0 0.3000000
Level:1 0.45000
Level:2 0.600000
buffType "BuffFighterBlinkActiveSniper"
effectInfo
effectAttachInfo
attachType "Center"
smallEffectName "Buff_FighterBlinkActivate"
largeEffectName "Buff_FighterBlinkActivate"
soundID ""
This is based on my sniper's Bullseye ability (instant death 30% of the time...increases per level)!
Now this will change the onDelay..so if you want to add a delay..You must link the PeriodicAction to a new buff in which you set the OnDelay trigger type (what you have at the moment) that calls a third row of buffs which is the final UnstabbleBuff that causes the effect!
So Like I said before, EXTRA LONG but possible!
