Set your max troop levels (G/S/M/E): the troop families you can field appear below (one row covers every tier sharing the name — Corax I–II, Vulture V–VII…). Enter the Strength/Health bonuses from your battle report for each row and for the siege engines, type how many Ariel you own, then press Apply. The calculator picks who to field and in what numbers. More in Instructions.
Type the bonuses exactly as the report shows them, decimals included — 2099.75, not 2100. Rounding changes a squad's striking strength and can flip the order in which your groups attack.
As long as this calculator exists, it will be free and open for anyone to use. If you'd like to help offset development time and costs, you are welcome to buy me a coffee. No obligation at all, but it would be greatly appreciated and would help me dedicate more time to improving the tool!
