Protect

Protect is an in-service Paladin ability that allows a Paladin to protect another from attacks. As you are trying to protect someone else and not avoid the attack (quite the opposite actually) evasion doesn't factor into the defense. A good soul state will help with Protects -- pristine soul gives a pretty good boost. They are all learned from the female sentry in the Crossing guildhall.

Protect Deflect

Circle: 3
Syntax: Protect <target> or Protect <target> deflect
Usage: Attempts to parry/block an attack made against another player. If the block misses, the Paladin can still reduce the attack, but then it's up the other player's defenses.

Protect Cover

Circle: 40
Syntax: Protect <target> cover
Usage: Takes on a full attack against another player. It has the same initial effect as protect deflect, but if the attack gets through the Paladin will take the blow with his or her own body.

Protect Assess

Circle: 60
Syntax: Protect assess <deflect or cover>
Usage: Actively scans a room for someone in need of protection. If someone is stunned, has low enough balance, immobilized, webbed, unconscious or has low vitality, the Paladin will either use deflect or cover on that person depending on the protect chosen when activating the ability.

Protect Self

Circle: 80
Usage: Protect self
Usage: Breaks up to seven negative effects (immobile, stunned, passive, webbed, prone, sitting, kneeling) on oneself. It won't work if the Paladin is unconscious.
