Here i have a short combo for newbies or unexpert proplr who find complex the long combos.
It's actually really easy. You will need to complete the Mq (Main Quest) in order to end up near Character lv150, so you can buy T4 (Lv4) Skills.
You will require: Impact + Meteor (Smite) + Finale (Smite).
The combo Will cost 5mp. As Meteor by itself cost 6Mp. So you will reduce 1Mp and buff the Meteor's Damage
