Splash

Splash is a term used for Basic Attacks and Abilities that require hitting a main target to cause its effect or (a portion of) its damage to affect nearby secondary targets. For splashing melee Basic Attacks, term Cleave can also be used.

Splashing attacks usually deal damage in a circle or an arc around the main target. The damage received by each unit affected by the splash, as well as the main target, is calculated independently depending on the state damage modifiers, such as Armor, affecting the unit. Basic attacks while Blinded will not trigger the splash nor do attacks against an Evading target. Evading targets additionally will not take even splash damage from attacks dealing Physical damage.

Splash damage from Basic Attacks can be affected by damage modifiers on the attacker (e.g. Executioner), but flat damage bonuses, dealing damage in a separate instance or of different type, usually only affect the main target, unless otherwise specified.

Bounce
Bounce is a mechanic similar to Splash that causes attacks to ricochet to enemies near the main target, damaging them by a portion of the attack's base damage. However, unlike splash, bouncing attacks can only hit limited amount of enemies at once. Some bouncing attacks can also chain, hitting enemies even further away from the main target. Aside from the target count, secondary attacks from Bounce follow the same rules as Splash.
