As an action, the restrained target can make a DC 15 Strength check, bursting the webbing on a success. The webbing can also be attacked and destroyed (AC 10; hp 10; vulnerability to fire damage; immunity to bludgeoning, poison, and psychic damage).

Reactions

Parry. Arachnae adds 4 to her AC against one melee attack that would hit her. To do so, Arachnae must see the attacker and be wielding a melee weapon.

Uncanny Dodge. When an attacker that Arachnae can see hits her with an attack, she can use her reaction to halve the attack's damage against her.
