Skills and spells in each of these classes are almost all useful. All classes receive:

Cloak:Adept	increases physical and spell damage.
Group heal	a spell that heals each player in your group for the same amount as a regular heal.
Carapace	increases hitroll and damroll by 20, Armor class by -100, and save vs spell by -13.
Summon shadowdragon	will summon a mount with a low amount of mana, but is very durable.

Once you reach level 30 in your realm lord class, you can gain one of two
unique legend classes for that rlord class. Gaining to legend won't grant you any more of your realm
class bonus, but will provide you with more powerful spells and/or skills.
Unlike previous classes, there is only a single legend level to be gained.
