A look at circumstance penalties and status penalties that debuff monster Armor Class. Use flanking or some other method to make monsters flat-footed to give them a -2 circumstance penalty to AC. Use poison, spells, consummables, ancestry abilities, monk or rogue feats, a critical hit with a spear and possibly other ways to give a status penalty to armor class. Finally, there is one other method, a forbidden lore we can't speak of and certainly can't write down, but it may be able to give ONE MORE tiny minus one penalty to armor class using an untyped penalty. All that AND a talking shake here on the Crunch McDabbles Show.
