New champion: Tangara-Demon of the depths

Hey everybody this is 1 of my first champion concept about a bilgewaters champion. I hope you like this concept and tell me what you think of it (my English isn't perfect so there might be some typos)

Short intro: Tangara is a medium ranged teamfight mage that uses her slows and her own minions to destroy the enemy, and give your team the team fight edge

Lore: Legends say a big sea monster claimed over a 1000 ships other say it was a witch, but whats true for sure is that this thing is not to be laughed about

Note It was unbelievable I was about to come back from catching fish and all of a sudden the water turned dark the fish around me swam away as fast as they could I looked around me And the last thing I remember is hearing something called 'Ihi-Nao'
