The Super Shot is an upgrade to a character's normal ranged attack. Once active, the Super Shot will obliterate whatever it touches. The Super Shot is a limited weapon, though, and characters will only have so many to use.
The Super Shot is an amulet that grants a hero 10 shots. This shot will destroy anything, including chests.
The Super Shot takes the form of a very large crossbow that fires a golden bolt. This wide bolt overruns everything in its path, destroying most targets and knocking down the rest. The bolt will persist for a very long time.
Works the same as in Legends. However, expect Generals and Golems to block this attack, making it less than ideal against them.
