Common (Damage Type)
Common damage is the type of damage that most weapons, abilities and creatures/mobs inflict. It is also the most easily mitigated, because armour contributes more to common damage reduction (100%) than any other damage type (20%). Most creatures have a higher than average common mitigation. For this reason, weapons with uncommon damage types, such as fire damage, deal more damage to them. This should definitely be taken into consideration when selecting a weapon.
