What does Helion's Hustle ability do?

The ability works out of combat, burning stamina for high-speed open-world sprinting.

This mobility tool is also listed under the name acceleration. It gives you a way to cross terrain rapidly between encounters, but maintaining that top speed continuously drains your stamina reserve.

Helion and Lunara share identical base stats and the same Light element, so Hustle represents Helion's distinct exploration perk at the start of the game. While Lunara attacks at range with magic, Helion combines this outdoor running speed with close-range melee fighting and break damage once combat begins.
