Banner that says "UPGRADE YOUR TRINKET"
This could be a thing that flashes on the screen every minute after you hit level 9 and havent upgraded your trinket.
It could also just be a simple reminder to upgrade them. Most dont even remember and have to be reminded. Others will pay the gold just to get rid of the annoyance. It's a nearly flawless system.
Any thoughts?
is the best item. Idk what you mean by "upgraded green trinket" but I figured you meant this.
is green.
