Flying

is an effect given to all airborne creatures and objects.

Creatures that are cannot be targeted by melee attacks from non-flying creatures. However, when, creatures gain a Swoop ability that allows them to attack non-flying creatures.

Flying is only possible on surface zones. Creatures cannot fly underground. Some subterranean creatures, such as, have the Wings mutation or a description that indicates that they have wings and can fly, however, those creatures do not actually have the effect from a mechanical perspective, and they can be targeted normally by melee attacks.

Swooping
Whenever a creature is, that creature also gains access to a Swoop ability. Swoop will attempt to attack an adjacent non-flying creature, with the attack functioning identically to a melee attack. When using Swoop, a creature will have a small chance of falling clumsily to the ground. The chance of falling to the ground is doubled if the swoop-attacker is shield blocked.
