The Pokémon Weakness Calculator will find all weaknesses, resistances, and immunities for any type or two-type combo possible. For those unfamiliar with Pokémon, every type has a set amount of weaknesses and resistances. What's challenging is figuring out what two-type comboes are weak & resistant to. Some of the more interesting type combos to try: bug-grass dragon-steel steel-ghost KNOWN BUGS: Clicking in between type tags in the selection phase may cause two type tags appear to be selected. However, if there are duplicated type tags (for example: fairy-ground-ground), the algorithm should only count ONE of the duplicated type tags (i.e., fairy-ground).
