Rough near-zero-wound sizing by boss power (keep / tier / count): ~1.5M = k21 t8 30k (Werewolf); ~4M = k23 t9 30k (Yasha/Manticore); ~18M = k25 t10 150k (Griffin/Minotaur/Peryton/Royal Thief/Witch1/Warlord1/Golem1/LavaTurtle1/Viking Easy50); ~65M = k27 t11 500k (Ifrit/Witch2/Warlord2/Golem2/LavaTurtle2/Ymir1/Pan-Ground1/Cerberus1/Bayard1/Nian1); ~90M = k30 t12 1,000k (Kamaitachi/Witch3/Warlord3/Golem3/LavaTurtle3/Ymir2/Hydra1/VikingNormal50/Nian2-3); ~160M = k32 t13 1,600k (Fafnir/Witch4/Warlord4/Golem4/LavaTurtle4/Ymir3/Cerberus2/Bayard2/Hydra2/Nian4); ~200M = k35 t13 2,200k OR t14 1,600k (Behemoth/Hydra3); ~270M = k38 t14 2,200k (Phoenix/Witch5/Warlord5/Golem5/LavaTurtle5/Ymir4/Cerberus3/Bayard3/VikingChief/Nian5); ~400M = k39 t14 2,800k (Jormungandr/Ymir5/Hydra4); ~550M = k40 t14 3,500k (Typhon). Jormungandr B16 and above always take wounds. Per-boss zero-wound cavalry thresholds (examples): Griffin B10 17.9M = t11 150k; Ifrit B11 = t11 400k / t12 200k; Kamaitachi B12 = t12 990k / t13 1.1M; Fafnir B13 = t13/t14 1.6M; Behemoth B14 = t13 2.25M / t14 1.595M; Phoenix B15 = t14 2.27M @+1526% atk; Typhon B17 = t14 ~3.3M (still ~29k wounded). Higher attack buff sharply cuts troops needed (e.g. Witch L3: 900k @+896% -> 2,024 wounded, but 900k @+1026% -> 0). Against-monster defense debuff also cuts it (Ymir L3: t13 1.064M -> 12k wounded at debuff 0%, but 0 wounded with monster Def -25%). Legend: t=tier, k=keep level. All counts depend on the player's research/general/gear buffs.
