Placeholder 

Storm Savant

Beginning when you select this school at 2nd level, the gold and time you must spend to copy a spell that does Lightning, Thunder, or Cold damage list is halved

Direct Storm

Beginning at 2nd level, you can direct the force of your storms. When you cast a spell that does lightning, thunder, or ice damage, you can add your intelligence modifier to the attack roll or half of it (rounded down) to the spell save dc.

Extra Blast

Starting at 6th level, your damaging cantrips can be imbued with the power of a storm. When a creature takes damage from a cantrip you can fire one additional beam or do one additional roll of its damage die, it dealing Lightning, Cold, or Thunder damage.

Empowered Storms

Beginning at 10th level, you can add your Intelligence modifier to one damage roll of any spell you cast that does Lightning, Cold, or Thunder damage.

Overchannel

Starting at 14th level, you can increase the power of your simpler spells. When you cast a wizard spell of 1st through 5th level that deals damage, you can deal maximum damage with that spell.

The first time you do so, you suffer no adverse effect. If you use this feature again before you finish a long rest, you take 2d12 necrotic damage for each level of the spell, immediately after you cast it. Each time you use this feature again before finishing a long rest, the necrotic damage per spell level increases by 1d12. This damage ignores resistance and immunity.
