Mikahils link skill reads:
Mikhail will be summoned and for 90 seconds, you will not be knocked back by monsters’ attacks. There is a 180 second cooldown.
Does this mean with a 4th job mage, you can reduce this to a 45 second cooldown due to Buff Mastery? Or will Buff mastery not affect the link skill. I'm just curious how it will work since it's the first active link skill in GMS.
