Unlike Beasts, Monstrosities are terrible creatures that exist specifically to prey on Sentient life. Though many are capable of speaking and can be reasoned with to an extent, they almost exclusively use this to further their own ends, ends which always include the shedding of as much Sentient blood as possible; if a Monstrosity at any point refrains from preying upon Sentients in the short-term, it is only because they believe that doing so will lead to further loss of life down the line (if they have the intelligence and patience required to plan so far ahead). Additionally, most Monstrosities are smart enough to have a self-preservation instinct and will not engage foes that are obviously beyond their abilties as well as flee from fights that they believe they have no chance of winning.
