Blast Phoenix/Freezing Spirit/Thunder Spear:

Phoenix does tons of damage and teleports you a short distance, great for closing space in a duel or chasing. Freezing is the first time you slow down the spirit of excellence in the field, which in some cases very good, but it is not pro. Lightning spear is a great post in a duel or otherwise Imitid flash. It does directional damage similar to blast phoenix.
Rating: A.

We do not have the final three spells, but we know what they do. By the way, we provide 2moons dil for you.

Infernal Pillar: Directional multi-target fire damage, causes a burn effect which diminishes an enemy's hp(2moons dil) through their shield in PvP. Knocks the enemy around a bit too.
Rating: A (For damage and functionality)

Gracious Eddy in 2Moons:
This can be pro if you use it well with Freezing Spirit. It's basically a targeted version of Freezing Spirit that hits the enemies around the target. Slows movement and attack speeds by 50% for 4 seconds. Useful if you are having your frail mage-body knocked around by a bagi. Damage on it isn't that great, but it has utility.
