Tools of the Dragon's Keeper
A keeper's grimoire of calculators, ledgers, and reckoning-tools — forged in flame, bound in parchment, and tended for those who walk the long road between hearth and hoard.
The Tools
◆ Choose your reckoning ◆
◆ Cross-path reductions, automated ◆
Research Calculator
Tally the cost of planned research across normal and dragon paths. Applies reductions from Thorned Bride and Dragonkeeper Armor as you go.

Dragon Calculator
Reckon the costs along the dragon path — every flame, every scale, every measure of patience the wyrm demands.
Wake the wyrm
◆ Upgrades, summons & ascensions ◆
Heroes Calculator
Plan hero upgrades, summons, and ascensions. Balance the cost of glory against the slow ledger of resources the realm can spare.
Marshal the host
◆ Forge-cost math, level by level ◆
Enhancements Calculator
Forge-cost reckonings for enhancements — every level, every material, every hammerfall counted before the bellows roar.
Strike the anvil
◆ Walls that outlast architects ◆
Building Calculator
Lay the keep stone by stone. Costs, upgrades, and the long arithmetic of raising walls that will outlast their architects.
Raise the walls
◆ Stamina, gold & the harvest ◆
Farming Calculator
The coinmasters' ledger for stamina and gold — what the fields yield, what the household spends, and what the keeper keeps in reserve.
Tally the harvest

These tools were built for a single purpose: to make the math disappear. Every calculator here takes the bookkeeping you'd otherwise do by hand and lifts it off your shoulders, so the only decision left is the interesting one.
