New defence : blizard tower

Attachment 27976New defence : blizard tower
this tower will be unlocked at town hall 11 and will work exactly as the inferno tower but instead it will freeze them the longer it stays on a unit the longer they will get frozen and of course the freeze spell can't freeze it for example :
just starting to shoot the unit : 10 damage speed decreases by 4
Getting longer with the unit : 50 damage unit can't move but if tower stops shooting the unit will instantly be able to move
already shooting with all its power : unit can't move and gets 500 damage and if tower stops shooting it the unit will still be frozen ( cant move ) for 30 seconds. Blizard tower and inferno tower will be smart for example the blizard tower is targeting a pekka and the inferno tower won't shoot that pekka ( because will obviously unfreeze it ) and will shoot another target same with inferno tower shooting blizard tower won't shoot at the same enemy.
When the blizard tower is shooting a air unit the air unit when frozen will fall to ground and will be able to be shot by cannons and mortars but not for the air defense until the unit is unfrozen and flies up again.
