Solo Kalli - Last Wish Raid l Season of the Deep l Solar Warlock

This took all of about 3 tries.
I had one Transcendent Blessing equipped... But besides that, I opted for double slugs just in case I goofed my shots on my Heritage.
Hit her as her shield goes down with Witherhoard.
Run to plate as shown in video (and many other guides).
Swap Loadout / Weapons.
Throw Grenade where she will be at, and finger snap the Thrall (spawn in by stepping on plate momentarily... Just don't stay on throughout the entire encounter).
Tractor Cannon / Grenade Spam.
Repeat until Final.
Make sure Heat Rises is on as this allows you to glide and throw your grenades, which in turn restores your grenade energy. Loadout I used below.
