    Note on Equipment penalty

    Your accuracy stat will be reduced if your weapon and armour styles do not match.
    To calculate this penalty, add 150% of the total armour you have equipped in the style your weapon is strong against to 80% of the total armour you have equipped in the style your weapon is weak against.

    E.g. if using a bow, magic helm, and melee body, enter 1.5 times the magic helm's armour value plus 0.8 times the melee body's armour value.

    You can also check this value in game - equip the gear you intend to use and open the Equipment interface, hover over your accuracy stat to see "hybrid nerf".
