Valor – Arena of Valor Skill Guide

Astrid dashes in the chosen direction and gains a Knight’s Mark for 5 seconds, stacking up to 2 times on herself. While she has a Mark, her next basic attack is empowered; enemies carrying a Mark are slowed.
1 Mark: her basic attack lunges at the target, transfers the Mark to it and deals bonus physical damage. When Astrid leaves the Mark’s area through a glowing point, she retrieves the Mark and deals damage again. The Mark can only be transferred to enemy heroes or jungle monsters; if the marked target dies, the Mark stays on the spot.
2 Marks: her basic attack winds up briefly, then lunges in with a slash that knocks the target back, deals bonus physical damage and heals Astrid; if it hits an enemy hero, she heals extra based on her missing HP.
