Invulnerability



Invulnerability is the ability to withstand any amount of physical damage or harmful force, causing little if any harm or pain to the individual. All beings with this ability bodies', except for God, The Darkness and Death, draw blood and can be pierced and penetrated by earthly objects but it doesn't do anything.

A high Invulnerability does not necessarily implicate many abilities. Leviathans are difficult to kill but posses few abilities.

A low Invulnerability does not necessarily implicate few abilities. Witches can be killed by anything that would kill a human, however powerful witches like Don Stark/ Rowena can cast many spells, even spells that can affect Leviathans/ Seraphs.
