Cost, time and bonus at every level

The Unbroken Line runs to level 6, adding +1.2% to defense and 100 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 13m 3s for the final level alone. Gems are only ever the optional instant finish; the study itself is bought with what your fields already make.

Iron Realms is an original work of fantasy strategy. It is not affiliated with, endorsed by, or connected to any other game or franchise, and “Iron Realms” is a working project name rather than necessarily the final title. Its lore, names and artwork are original or used under CC0/CC-BY/OFL licences (see the in-game Credits). The community section also hosts unofficial fan tributes — quizzes and diversions made for fun, not part of the game — which name other fictional worlds under their own labels and are likewise not affiliated with, endorsed by, or connected to their rights holders.
