Aldor Exalted effect

 * The Aldor proc grants +200 Attack Power for 10 seconds.

Scryers Exalted effect

 * The Scryer proc grants "Arcane Strike," which inflicts 333 to 367 Arcane Damage.
 * The Scryer proc is treated as a separate melee special attack that does non-physical damage; it can miss, be dodged, be parried, and be blocked. It can also crit for double damage.  Melee Hit Rating, Crit Rating, etc. all affect the odds for this, as for any other melee attack.
