Some good info that include Seal and Judgement of Command .

The attacks of some monsters that do magic damage are actually treated as melee attacks, and use the standard melee auto-attack rules. For example, the melee attacks done by a fire elemental inflict fire damage, but they're resolved as an ordinary white-damage auto-attack—they can miss, be dodged, be parried, be blocked (as of Patch 3.0), and do double damage on a crit. The only difference between how a magic-damage melee auto-attack, and an ordinary physical damage melee auto-attack, is resolved is that if the target has any resistance to that school of magic, the same check is made to see if the damage is partially resisted as would happen from a spell.
Magic-damage melee special attacks
Some monsters also have melee "specials" (the equivalent of yellow-damage attacks done by players) that do magic damage. For example, the Crystal Strike ability of the Erratic Sentries on the Isle of Quel'Danas inflicts Arcane damage, but is resolved as an ordinary melee special attack—it can miss, be dodged, be parried, and be blocked, and does double damage on a crit. The only difference between how a magic-damage melee special attack, and an ordinary physical damage melee special attack, is resolved is that if the target has any resistance to that school of magic, the same check is made to see if the damage is partially resisted as would happen from a spell.
A few player abilities, such as a paladin's Seal of Command, are likewise resolved as yellow-damage melee attacks that deal non-physical damage. The odds of the various attack results occurring with one of these attacks are determined the same as for physical melee attacks—the base chances are determined by the player's Weapon Skill with the wielded weapon, the miss chance is reduced by the player's Hit Rating, the chance to be dodged and parried is reduced by the player's Expertise, and the chance to crit is increased by the player's Agility and Crit Rating.
Magic-damage ranged special attacks
The Arcane Shot of a Hunter, and the Hammer of Wrath and Avenger's Shield talent of a Protection-specced Paladin, are resolved as ranged attacks that do non-physical damage. They can miss—rather than be "fully resisted"—and they do double damage on a crit. The only difference is that if a mob target is higher level than the player attacker, or if the target has any resistance to the school of magic used by the attack, the same check is made to see if the damage is partially resisted as would happen from a spell.
The odds of the various attack results occurring with one of these attacks are determined the same as for physical ranged attacks—the base chances are determined by the player's Weapon Skill with the wielded ranged weapon (in the case of Hunter abilities), the miss chance is reduced by the player's Hit Rating, and the chance to crit is increased by the player's Agility and Crit Rating.
