Gloom Shroud

For 10 seconds, Shadow Step can be used at no cost.
Level 1: While in Gloom Shroud you have 100% piercing.
Level 2: Dashing while in Gloom Shroud causes a nearby enemy to be pierced by shadow as if Niss had Umbral Aura. This does not consume Umbral Aura stacks.
Level 3: After Gloom Shroud ends, all nearby allies gain 3 stacks of Umbral Aura and Niss gains max stacks.
