Dome Keeper - 200 Iron in 30 Minutes Guild Challenge - Attempt 5

This was pretty hard ngl took me like 3 hours or so. No waves only mining for this guild challenge. The Assessor is way better than the Engineer I don't think I can go back. More fun too. The hard mode version of this challenge I don't think you could do it 95% of the time with the Engineer. Start - 0:31 Upgrade I don't use - 4:45 Winning upgrade - 9:45 Portal Upgrade (kinda didn't work to teleport with my bundle)- 25:00 About halfway through I also found this squid thing on the map that takes the material back 1 by 1. I think that was pretty key, along with the tree. The tree gave me like 15 iron.
