Some ideas for improving towers

So clicking on a tower shows their items, right? If they don't get buffed, at least let us buff them in-game by ourselves The fountain shop would have few items that can be used only on turrets It would not be worth to add a whole new currency for them, but maybe sacrificing some experience to buy the items and upgrade the turrets would be a good idea, at least in my opinion

So, I have some ideas of items in my mind I'll put here

(keep in mind that when you activate the item, it only applies to the closest turret to you) I get that some of those might be dumb, but yeah

1. Turret stone wall - +75 armor +600 HP +Turrets regenerate 100HP every 1 minute and half

(Active) - Creates a wall that surrounds the turret's shot area that falls over in 2 seconds. Enemies caught inside can't leave the wall. Dashes can go through -can be activated by players that are in the area of the turret, 120 second cooldown

2. Indestructible will - can't be activated by any players, activates passively +500HP +50 armor (Active) - Enemies attacking the turret proc "indestructible will": Damage dealt to the turret over the following 10 seconds is completely negated. After 10 seconds, the turret's hp regenerates back to maximum

3. Poisonous laser +100 AD to turrets -10% damage taken from basic attacks to the turret

(Passive) - The turret's damage is doubled, and turned into true damage. With every shot the turret has shot, the turret gains attack speed and bonus armor penetration

Any opinions?
