The Bear Trap is a pure damage check: the bear never fights back, rallies cost no stamina or march slots, and only Attack and Lethality matter. This calculator turns your troop pool into the optimal main-rally and join-march composition in seconds.
Upload a screenshot of your troop screen and on-device OCR fills Infantry, Cavalry and Archer counts automatically. Add your hero capacity buffs and per-troop research ATK bonuses, pick a doctrine, and get exact troop numbers for the main rally and every join march — with a pool guard that warns when the plan exceeds what you own.
Savage Advantage adds 3,000 squad capacity per hero level. Fearless Roar (Bison) adds 1,500 per level for 2 hours. Deadly Bite (Gen 5 Alpha Black Panther) adds 2.5%–10% troop lethality, and City Deployment Boosts raise rally size 10% or 20%.
Archers deal a 10% damage bonus against the infantry-type bear, battles always run the full 10 rounds, and damage is consistent with no random rolls from the target. From Gen 4 upward the baseline is 1% Infantry, 10% Cavalry, 89% Archers with a 5,000-infantry absolute floor; the Smart Ratio tunes this from your ATK percentages.
As host, all three heroes' Expedition skills and your full gear apply, five rallies per event. As a joiner, only the first Expedition skill of your left-most hero counts, six marches per event — so level your top four joiner skills and never send chance-based heroes like Jabel.
Group A joiners (Chenko, Amadeus, Yeonwoo) add flat squad lethality; Group B (Amane, Margot, Luna) multiply against them — a mixed rally out-damages four duplicates. Luna, the Gen 8 archer, is the newest S-tier addition; Diego and Liz add nothing to Bear Hunt.
