support skills pet question

the one that increase crit,atk,matk how long are their duration?
and does pet keep spamming those skill untill it has no mp or it will wait untill the buff is gone before use it again?

 

duration is 10 seconds each.
the pet will spam the skills until it runs out of MP. the waiting time between casts depends on the attack pattern. higher numbers have a longer cooldown time.

 

so,to prevent the pet spamming same buff i should use high pattern?
or it will keep spamming but it slower because high pattern has slower motion?

 

it will keep spamming, but higher patterns have longer cooldown times, so it might wait until end of the buff before casting it again.
