Hello!

I'm pretty new to the game, still in the free trial and I have a level 37 Black mage.

I'm wondering if there's an optimal order/ way to use my abilities? I'm kinda just spamming fire and using transpose to swap to ice when I'm out of mp And trying to keep thunder or thunder 2 up (not sure what the difference is really). Also all the numbered abilities (like fire, fire 2, fire 3 etc), are they straight upgrades that I should just be using instead of the ones that came before or should I have them all on my hotbar?

Thanks for the help! I just want to make sure I'm not holding my group back any more than I have to in dungeons, I'm already on ps4 using controller and stuff
