AoE bonus mechanics

Main Article: Interactions

The AoE bonus affects most No Target circular radius abilities (e.g. Scream of Pain) and Target Area circular radius abilities (e.g. Shrapnel).

AoE Bonuses affect all Auras and Cleave sources (e.g. Lunar Blessing, Great Cleave).

AoE bonus also affects most Target Point abilities with line-shaped radius (e.g. Boundless Strike) and cone-shaped radius(e.g. Breathe Fire), leads to an expansion in the width radius of the Abilities' Hitbox.
Despite some line-shape Target Point abilities such as Meat Hook, Timber Chain do not receive the AoE bonus.

Earth Spike and Impale are special cases as they do not have Effect Radius and Hitbox Radius increased, despite AoE Radius being increased.

Target Unit abilities have a Search Radius to fire secondary projectiles (e.g. Fade Bolt) are always affected by the AoE bonus.

Target Unit with Area Effect abilities (e.g. Storm Hammer) are always affected by the AoE bonus too.

Unlike Cast Range bonus, which causes all Vector Targeting spells have their cast range increased but not their effect range.
AoE Radius bonus make almost Vector Targeting spells have their effect range increased.

• Example :
  • Swashbuckle has "75 Slash width" increase when equipped with Gleipnir.
  • Aether Remnant has "75 Remnant Watch width" and "75 Remnant Search range" increase when equipped with Gleipnir.

These values have affected_by_aoe_increase tag in the game key value files.

The following abilities do not have their effect radius increased, despite their AoE Radius being increased. This means their Effects Radius do not match the new AoE Radius. Also, some abilities are listed for clarification purposes.
