Another good way to learn mechanics, is by memorizing some of the names. Specific ones are often reused on multiple enemies, such as "swing" attacks always being a point-blank circle AoE with the monster at its center or Charybdis always getting you to single digit HP, to name some examples.
Also important to note, is that reused character models often share abilities as well ( like that one dullahan boss from amdapor keep HM having some skills that Odin has as well).
