The following restrictions apply:
- Account is totally fresh
- Joining a clan for blueprints is allowed
- Every node must be done solo
- No trading, except for transferring a prime set of the frame of your choice (if a prime exists)
- Specters and Skaut are allowed, but please note if your strategy would require them for certain nodes
- Helminth abilities are allowed
Off the top of my head, my top picks for this challenge would be Nyx, Limbo, Octavia and Frost since they have good CC and objective defense, and good weapon support; “complete” frames if you will. Loki, Zephyr and Banshee would all also be good picks, although missing elements from their kit here and there.
Gauss if obtainable would be a very fun frame to Iron Man. However Sedna is quite late so I don’t know if he’d count.
Considerations like that are why I decided you can trade a prime set over so that more frames are available from the start.
In the ideal thought experiment, you’d just start with the frame.
