Way to buff turrets while still letting people attempt a quick tower cap early
First, triple tower hp. Second, put a flask in the shop that increases damage dealt to towers by 200%. This flask costs ~800 gold. Buff lasts 2 minutes. If killed, buff is transferred. Additionally, the item auto applies if you haven't already after 2 minutes. Finally, this flask cannot be bought after 25 minutes.
What this accomplishes: The status quo of tissue paper towers (TPT) is now an opt in. So if you're a Yi and you wanna try to go for a tower at 8 minutes, you can do it by investing 800 gold. However, if you misjudge the situation, you will end up wasting this investment. If you are facing an enemy using a flask, ganking them and stealing their buff is incredibly good counterplay just like red and blue buff. Preventing people from buying the flask after 25 minutes keeps dps from getting out of control mid and late game vs towers. The point is to invest 800 gold EARLY for an EARLY tower, NOT for generic tower damage.
An early tower SHOULD be an option, but the risk should be immense because the payoff is awesome.
