Gameplay

Your main job as swap [Loki] is to swap ([Loki]'s 3) places with the drone to get it to the boil waypoint as quickly as possible.

Bring a weapon with a scope to get better aim for your swap. You should also have a reasonably speedy [Itzal] build to set up swaps quickly. (See: Free roam itzal )

Drop a decoy near your swap spot so you can swap with it right after swapping with the drone.

If you accidentally fly over the boil and go down while positioning yourself for a swap, just use a respawn.

Killing thumpers while doing PS phases is also pretty easy while stealthed.

Build considerations

Ranges

280% - 210m
265% - 198.75m
235% - 176.25m

Anything over 200 is probably fine, you're limited a bit by the terrain unless you have good coordination with the [Nova] to get the drone airborne. Just be sure you know the exact max distance of your swap so you can position yourself accordingly.

Forma

You can choose to not forma over the vazarin spot, but your normal invis [Loki] build can only take one, so it's better to cater to that.

[Irradiating Disarm]?

[Irradiating Disarm] is helpful for p2 if you're helping new players out. You can replace it with [Sure Footed] or another defensive mod otherwise. This build as it is can be used as a disarm loki after the event is over, so it's good to keep around.

Arcanes

Energize / guardian / resistance / arcane essence helmet are all helpful here.
