NB. Lore is calculated as ((level * rate) + int_bonus + wis_bonus). Intelligence and wisdom bonuses are from lorebon.2da and the rate is the lookup value in lore.2da, based on class. For multiclass characters, (level * rate) is calculated for both classes separately and the higher of the two values is used - they are not cumulative.
