For example, with a tier 90 main-hand weapon and shield (and no other equipment), and level 99 Strength and Defence, Bash deals 20-100% of damage. Under these conditions, the normal ability damage is , so this corresponds to a 30.6–153.1% ability. This makes Bash one of the more potent basic abilities, especially as several of the strong basic abilities are not usable with a shield.
Bash works no differently when using a defender, however the values change as defenders have different equipment stats. Using the above conditions with a tier 90 defender instead of a shield, the effective ability damage of Bash is . As the normal ability damage is increased to , this now corresponds to a 24.7–123.7% ability. Despite the lower percentage, this means that Bash is stronger with a defender than a shield. Generally, this further means that while using a defender, Bash could be used to replace Tuska's Wrath in a revolution bar while not on a Slayer assignment against the target.
- Before the Legacy Mode update, Bash would stun the target and deal 100% weapon damage.
