God Idea: Caïssa the Godess of chess

Hi! I am here bringing an idea I though of.

Caïssa:
-Auto attacks: Throws chess piece.

Passive: Planned attacks
Caïssa's attacks use a 5 swing chain, the 5th hit firing 5 projectiles instead of 1.
Minions kills gain charges that grant Caïssa +2 damage per stack. Max 15 stacks.
Stacks last 30s

Ability 1: Pieces of death
Upon activation Caïssa holds a specific chess piece in the air, you can then reactivate the ability to cycle between pieces. When you have the piece you want hovering above you your next auto attack will have a bonus based on that piece.
Mana cost: 90/100/120/140/160 . Mana is used the moment you attack, not when selecting
Cooldown: 20s
_______________________________________________________________________________________________
Pieces:
Knight: Upon hit drains 35% speed gaining it for Caïssa
Castle: Upon hit deals AOE damage
Bishop: Upon hit restores 150% of mana used to cast the ability
Queen : Upon hit stuns target for .5/1/1.5/2/2.5s

Ability 2: Ironclad Defence
Caïssa summons a large castle piece at target location, it will act such as a tower. It will share 50% of Caïssa's stats dealing magic damage each hit.

Ability 3: Tactical assault
Caïssa activates an aura that decreases enemy damage by 10/15/25/30/40, also slowing them for 15%
Mana cost: 60/70/80/90/100
Cooldown: 10s
Duration: 5s

Ultimate: Make your move
Caïssa shoots all gods in a LARGE raduis (enemies and allies) into the air onto a giant chessboard where they are placed on random squares. Enemies will only be able to move 2 squares while allies can move 4, they are free to auto attack. Allies gain bonus damage and protection, After the duration enemies are slammed to the ground and are stunned for .5 - 1s

If you don't want to read much just read the ulti :D Its the main idea I had so I built a god around it

I think her 1 is really cool, but her ult could be really trolly though. And just a question, is this a real goddess?

I see your point. But then again... Odin's ulti is also trolly, Yimirs wall is trolly. Need I continue?

All gods were created by humans and this god was created in Italy but after the fall of rome.
