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. 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, knocked off balance, immobilized, webbed, or has low enough 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 stuns, webs, and immobility on oneself, and if the Paladin is prone, sitting or kneeling brings him to his feet. It won't work if the Paladin is unconscious.
