Invincible (インビンシブル, Inbinshiburu?), also known as Hallowed Ground, is a recurring Knight ability in the series. As the name implies, the ability makes the user immune to all damage for a short period of time.
Invincible is the special job ability available to Paladins. As with all special job ability, it is available at level 1. The ability, when used, will make the Paladin completely immune to all physical attacks for the next 30 seconds. The Paladin can still be damaged by magical attacks or degenerative damage over time effects like poison. This ability also creates a massive, nearly unequalable, amount of enmity, all but ensuring the Paladin will gain the attention of the enemy and absorb its futile attacks.
Hallowed Ground (Invincible in Japanese) is a Paladin ability available after completing the "Keeping the Oath" job quest at level 50. The ability renders the user impervious to most attacks for a period of 10 seconds. The ability has an instant cast time and a recast timer of 420 seconds.
