Lono, Hawaiian God of Storms (Ranged Mage)

Hey guys, I'm back with another Hawaiian pantheon idea.
Personally I think Hawaiian gods are pretty cool, and I've released an idea already - Pele, Hawaiian Goddess of Fire. It got over 1k views and is probably the favorite among my ideas.
I figured I'd hit it again with another one.
This time, Lono, God of Storms and Weather.

Passive - Storming
Lono starts the game as a whipping wind gust. In this form, Lono gains significant extra HP5 and MP5.

At each level of his ult, his storm become more powerful.

At first level, Lono becomes a larger wisp of fluffy white clouds. In this form, Lono gains 10% more movespeed.

At second level, he gains lightning surging throughout him, granting 20% of his magical power per autoattack.

At third level, Lono becomes a waterspout (water tornado). Lono receives a magical protection debuff aura.

At fourth level, Lono turns into a group of low-hanging stratus (storm) clouds. Lono has 15% more magical power in this form.

At fifth level, Lono's FINAL FORM, he gains 50% of all the previous buffs.

Ability 1 - Cloudy Skies
Lono coats target area in a thick cloud cover, dealing 50/80/120/150/180 (+10% magical power) every second to enemies in the area. They also have their sight range reduced to 50%. Lasts 4/5/6/7/8 seconds.
Cost - 90 mana
Cooldown - 10 seconds

Ability 2 - Bolt
Lono fires a short range bolt of lightning that deals 90/150/190/250/290 (+60% magical power) magic damage on impact. If the enemy hit stays within a radius of Lono, half that damage is dealt to the target every second, for 4 seconds.
Cost - 70 mana
Cooldown - 8 seconds

Ability 3 - Hidden in the Clouds
Lono fades away into the clouds for 4/5/6/7/8 seconds, gaining 15% more movespeed and causing 20/30/40/50/55% of enemy autoattacks to miss. Lono loses 15 protections and his spells penetrate the same amount of the enemy's magical protections.
Cost - 120 mana
Cooldown - 20 seconds

Ultimate - Eye of the Storm
Lono concentrates all his storm energy into an small area. After 1.77 seconds, a massive blast of lightning, wind, clouds and gases pummel all enemies in the area for 300/400/500/600/700 (+80% magical power) magical damage.
After using Eye of the Storm, Lono gains a double to whatever buff he has from Storming for 10 seconds.

Will add colors and such. Just wanted to get this up while I update my computer.
