Order

Orders are necromancer enchantments that give the entire party a boost to their attacks. The orders present in the game right now are:
 * Order of Apostasy: adds enchantment removal to party attack.
 * Order of the Vampire: adds life stealing to party physical attacks.
 * Order of Pain: adds damage to party physical attacks.
 * Order of Undeath: adds damage to your undead minions (not an enchantment)
 * Dark Fury: adds extra adrenaline gain to party attacks.

In general, Orders last a short spurt and involve health sacrifice or loss for the caster. Also, since the March 2nd 2006 update, Order of the Vampire no longer stacks with any other Necromancer Enchantment.

Note: The skill Dark Fury does not have "Order" in it's name, and it says "nearby party members" in its description, but it behaves just like an order (requires sacrifice, affects all party members in radar range, lasts for 5 seconds).
