A Melee Attack is an attack that requires the attacker to hit the target with one of their Melee Weapons at close range.
Melee attacks begin with a base 10% chance to hit. This chance to hit can be increased by certain skills (such as Martial Arts), spells, potions, and other effects. It can also be decreased by the weapon being a heavy weapon, which inflicts a -10% chance to hit penalty.
The target defends against melee attacks by having certain skills (such as Dodge) or other effects.
