Phoenix Flash (Sometimes restore HP when attacks hit)

[Route A,B,C] Hidden in Desert: Center and requires using the Pod Scanner (available on route A after Submerged City main quest). Assuming the entrance from Desert: Camp is due south, it can be found around the south-east-south edge of the "save-available" area (visible on the minimap as a brighter circle). The large pipes that show up on the minimap should still be visible.

A few tips to make Phoenix Lance easier to find:
From Desert: Center, face East  (assuming you use a non-rotating mini-map).
The Lance is EXACTLY towards the Rocket platform made by the Half-Wit Scientist. At the halfway point towards the Lance you'll find a small treasure chest in the sand.

Finish Blast (Adds an additional attack after finishing a combo)

Alternatively, you can remote control one of the worm machines via hacking. Once controlled, use the worm's dash move followed by their jump to slowly glide over to the building. Self-destruct the controlled machine once their, and your character will spawn in their place, allowing you to open the chest there.
