The interaction between strong/weak and resistant/vulnerable and attack/defense/stamina seem confusing at times. On one hand the first two categories seem analogous – that being strong against a type and being resistant to it mean the same thing (until we see that Fighting is listed as weak against Bug, but also resistant to Bug). Does strength affect the chance of an attack connecting? Or the damage done if it connects?
There are really only 4 combinations (strong+resistant, strong+vulnerable, weak+resistant, and weak+vulnerable) and it’s tempting to view the strong/weak as applying to attack and resistant/vulnerable as applying to defense; but it’s still a challenge to identify clearly and quickly which mons match up most favorably against which others in a conceptual way (without resorting to long hours on battle simulators).
I’m trying to find a writeup that makes sense of that stuff. Is there a definitive clarification already out there?
