Pan is the exception to the mounted-only doctrine: it has three variants and you must MATCH the counter troop type. Attack matrix (damage vs the boss's type): Ground troops vs Pan(Ranged) = 408% (best), vs Pan(Ground) = 90%, vs Pan(Mounted) = 70%; Ranged vs Pan(Mounted) = 367% (best); Mounted vs Pan(Ground) = 140% (best); Siege = 50% vs all (never use). So: Pan(Ranged) -> Ground; Pan(Ground) -> Mounted; Pan(Mounted) -> Ranged. Example zero-wound: Pan(Ground) L1 22.3M = t11 mounted 372k; Pan(Ground) L3 122.9M = t13 mounted 1.5M @+1000%. Best speed-ups; drops runestones + tactic scrolls at L4+. 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).
