Whole idea of this build is spam switch teleport - Build should give like 15s invulranibility if targeting enemy. If ally then they get like 20s?

[Rolling Guard] is just additional invulnerablity insurence

[Xata]'s Whisper is just there for weapons to deal addtional damage
If Arcane Energize is missing swap [Nira's Hatred] for an efficency mod and can use another arcane of choosing

If you care about lokis other abilites and have Arcane Energize then can swap [Nira's Hatred] & [Augur Message] for [Hushed Invisibility] & [Irradiating Disarm]
Cloaking just acts as additional insurence
Ult is just very nice CC
