1x Training camp level 11
I would strongly advise leaving 1x Training Camp level 11.
Stronghold 25
I would really like Stronghold 25 unlocked since I am unlikely to build Alchemy Lab, unlikely to build Hero Academy and unlikely to raise Hunter’s Lodge to Level 5.
Right now I am using extra iron to create harpoons ( so so many harpoons) and level my Advanced Farms ( I have not collected food from farms for 33 days ).
