Fracture

The Fracture is one of the first few towers you can get from defeating the boss of a certain map, which in this case the maps are Canyon Calamity and Volcano Valley. Upgrades for Fracture are shown below. This tower is one of the best towers to do damage with when upgraded. I'd recommend atlleast having this tower in your deck at all times until another, better, tower is showcased. This tower has a limit of 7 because of good it's damage and range is, plus even combined with a maxxed Spectre, even some Hard mode bosses can't get past them. The mana cost for upgrades are shown below. Below are pictures of all Fracture levels, just for reference or if people want to see them.
