The broken weapons of the Sunspears have become daggers in the hands of their descendants, which they use to strike at the very fabric of magic and strip it from their foes. They meditate to see past their enemies' defenses, and they use their adrenaline to counter attacks.

Adrenaline Burst

You can use Adrenaline Burst's up to a number of times equal to your Strength modifier (minimum of once), and you regain all expended uses of it when you finish a long rest.

If an option requires a saving throw, your Adrenaline Burst save DC is calculated as follows:
