Mages of Mystralia

An easy way to get through the tower quickly is to use the "Storm" spell created by Steam user raven0ak, as seen in his/her steam guide here: https://steamcommunity.com/sharedfiles/filedetails/?id=93009...

This spell uses up a fully upgraded mana bar in seconds but does tons of A.o.E damage. It is recommended to use this spell with the Trial Wand you receive for finishing the Trial of Mages in under 10 minutes. Note: Using this spell will also help you clear the trial in about 5 minutes, though you may want to use some Mana Charms instead of waiting for your mana bar to refill after each attack.

Start with the Actus spell and change it to the Aura/Air element. Equip Duplicate to the center and Size to the Duplicate. Equip Homing to the center and Teleport to the Homing. Equip Mastery to the center and equip Impact to the Mastery. For the Impact spell simply use Immedi with the Aura/Air element with only Detonate equipped. Equip Proximity to the center. For the Proximity spell simply link the spell back on itself, i.e. choose the spell you are currently creating.

This is all you need for the Impact spell: https://imgur.com/gewDMxX

You may want to switch to another spell to finish off any creatures with Aura/Air resistance, but it isn't really necessary.

If you don't get this on your first try it's okay, after the credits role, you can go right back to the tower, make sure to speed past dialogue, my first try was 13-14 minutes my second try was 6-7. So fear not, and you can do it as many times as you'd like to get there, just try out different spell combos to get what works right for you.
I mostly used 1 spell, raining large fireballs on my enemies, I just made it to where it took nearly no mana to cast, and used electric blasts to hit anything that was immune to fire.
