D20r:Wizard

'''1st Level Mystery:''' You gain a bonus on Awareness checks equal to your Charisma modifier.

'''4th Level Mystery:''' You are gifted with extraordinary insight and perceptive abilities: you can add an insight bonus equal to your Charisma modifier to any attack roll, saving throw, skill check, or level check you make. You can use this ability once per day, plus one additional time per day for every five class levels attained. Using this ability is a free action that can be taken out of turn if needed, but you must choose to use this ability before the die roll is made.  

'''8th Level Mystery:''' A number of times per day equal to your Charisma modifier, you can generate a protective aura that shields against both physical and magical attacks. When you generate this field, you gain a deflection bonus to your Armor Class and a resistance bonus on all saving throws equal to your Charisma modifier. This ability requires an immediate action to activate, and each use protects against only one attack or spell. Once activated, the protective aura lasts for 1 minute or until you are attacked or required to make a saving throw, whichever comes first.

'''12th Level Mystery:''' You gain spell resistance equal to your caster level + your Charisma modifier.
