it will look a bit like this poseidon

pros: high damage output

con: very mana dependent

the ground where he stands turns into water(other units and demigods can still walk over that ground/water)

has the ability to change into a big shark

in his normal form he can summon powerfull sea creatures the ground the creatures are swimming on is turned to water (just like with the ground the demigod stands on)

active skills in normal form:

1. the kraken an octopus like creature that slows opponents (lvl increases hp and slow rate of the kraken)

2. small sharks (lvl increases max amount and spawned each lvl)

3. flood a wave of water that does damage(damage increases each lvl)

4 switch to shark mode (in shark mode hp regen and armor is increased but mana regen decreased)

active skills shark mode

1. dive and return to the surface with a strong bite attack (lvl increases distance and damage)

2. increase size, damage, armor and hp regen even more but drains mana and unable to cast any other spells while activated(lvl increase size, damage, armor and hp regen) 

3. create a water pool around you increases allies move and attack speed and decreasing enemy move and attack speed(lvl improves the effect)

4. return to normal mode (in normal mode hp regen and armor is decreased but mana regen increased)

Passive skills:

bloodlust: while in shark mode he gains increased move speed if wounded enemy demigod is near(lvl decreases the amount of hp that is necessery for the effect to be working and increases the move speed)

more is coming

any ideas will be apreciated.
