Shadow Walk's backstab applies to every hit during the fade time without breaking the invisibility
Shadow Walk applies its damage to every hit during its fade times, without breaking the invisibility, allowing the player to apply its damage multiple times per cast. According to the description, only the attack which breaks the invisibility should apply the damage. This means attacks during the fade time should not apply the damage, since these attacks do not break the invisibility. Vendetta
, Wind Walk
and Shadow Walk
also have this bug.
