Age of Origin guide reviews the giant cannon event.

Personally I don’t like the interface and it feels awkward to control that being said….

The daily rewards you should do for the items it’ll take your cannon to level 7. $2 invest gets you to level 10 and unlocks the first pay rewards. +$6 more to unlock level 15 cannon. I was told $50 total would get you to level 25 cannon.

Camel provides no transparency on how to calculate the additional cost of each level up for the cannon and at minimum that absolutely should change about this event. Players deserve to have a way to calculate how they spend their money for rewards.
