RoK Calculators
Plan your troop training and resources. Save an inventory on your profile and every calculator prefills with your numbers automatically. They all work without one too, just enter values by hand.
Troop Training
How many troops your speedups can make (with the resource shortfall), or the resources, speedups, power and MGE / Pre-KvK points for a target batch.
Resources
Work out the food, wood, stone and gold needed for a goal (including troop training) and the gap versus what you have, with your Pick One chests allocated to cover it.
