upgrade limit

Hi all, I'm new here so if this is the wrong section, excuse me

I want to ask is there any way to increase the upgrade limit?

Thanks!

Go to main building and buy VIP mode with coins, this gives you an extra upgrade, attack and hunting slot. Also it removes the 15 seconds chat limit too.

It also allows you to construct three types of units at once, as opposed to two.

it also gives you a vip title after your name on WC which is the best bit!!

I thought he meant upgrade past level 20... Then I read y'all's posts >.<
