Hey Nicholas6621! I am a storm wizard myself (not maxed level) and I would love to share my strategy with you. Most people go with a secondary school but I'm not a fan of that. I first would train all the way up to tower shield and feint. Those are good spells to use wherever in the game. The next thing I'd train is astral spells. I am only training sun right now. Those spells include strong, keen eyes and etc. For a storm, damage is the way to go so I'd only getting the one with damage. The rest is up to you or if you take someone else's advise.
I would like too say that I was a wizard, and would definitely recommend a second spell school. For me it was but since you're a wizard I would recommend ,, or to counter act balance, and make a more flexed character.
As a max Diviner, you may want to consider learning/getting the essentials:
to Tower Shield - Helps with your defenses
to Feint - Helps capitalize on your massive offenses.
- Amplify, Fortify, Galvanic Field and the optional Berserk.
- All the damage enchanting spells only. - Tough, Strong, Monstrous. The keen eyes, accurate is not necessary and completely optional. With storm's already high pierce, these cards are not necessary.
- Again, completely optional. As a , you'll get access to your own spell (Healing Current) arguably countering Life's Satyr. With your high critical, the spell should prove very beneficial.
- Be sure to pick up the elemental blades from the Balance Tree in Krok, the traps are not necessary.
