Captain configurator
Pick a captain, set its level and stars, and give it an artifact and three pieces of gear, each with a gem and an enchantment. Underneath is what every bonus adds up to, and where each part of it comes from.

Pick a slot above to start.
Each bonus is added only to itself: army strength and melee units' strength stay on separate lines, the way the game keeps them. A bonus to strength and health counts in full towards both. Courage, tenacity and determination are left out, because they are not percentages.
