Sphinx = event boss, the main BLAZON drop (and Source of Life at L4+). Mounted. Zero-wound cavalry: L1 12.4M = t11 100k; L2 22.3M = t12 300k; L3 74.5M = t12 900k; L4 147.5M = t13 1.578M -> ~6k wounded @+1066%; L5 225.2M = t14 2.161M @+1546%. Buff breakdown example: 1,546% = Mounted Atk 1,413% + Against-Monster Mounted Atk 103% + In-rally Atk 30%. Doctrine (all normal/most event bosses): fight with only the single highest tier of MOUNTED cavalry, one wave, to one-round-kill for zero wounds; buff mounted attack first, count second. Skill books: Mounted Attack Against-Monster Lv4, Mounted Attack Lv4, March Size Lv4. Add an AGAINST-MONSTER debuff (not a normal debuff), e.g. Dragon Equipment Set (4); monster Def debuff caps at -50% (5x set). In a rally only ONE joiner needs the against-monster debuff -- it does not stack across joiners. Monarch Talent Lv6 'Mortality' halves wounds. Rally-join = 1 general + 1 mounted troop (loot-agnostic).
