Cost, time and bonus at every level

Diplomacy runs to level 12, adding +1.2% to gather_yield and 72 power each time. Studying it out costs the four soft resources — the same amount of each — and takes 34m 21s for the final level alone. Gems are only ever the optional instant finish; the study itself is bought with what your fields already make.

Taken from nothing to level 12 that is 2h 22m of raw study and 891,923 of each of food, wood, stone and iron — 3,567,692 resources in total. Levels above 10 additionally consume an advanced forging material, one more unit per level past the threshold, so the last 2 levels also need the forge working.

Where it sits in the tree
