Rune Shift (Su)

Whenever you overload a script with at least one alteration runic charge, you gain a minor alteration to your physical form. You can select from the following benefits:

• One claw, bite, or gore attack, which deals damage as appropriate for your size. You can select this benefit multiple times.
• Darkvision 30 feet
• The scent ability
  
• Swim speed 30 feet
  
• Climb speed 30 feet
  
• The ability to breathe underwater
  
• +10 feet to base land speed
  
• +2 natural armor bonus
  

You gain one of the above benefits for each alteration runic charge used, and the benefits last for 1 minute.

Transformation (Sp)

At 14th level, you can alter your form. This can function as elemental body III, form of the dragon I, or monstrous physique III. At 18th level, it instead functions as elemental body IV, form of the dragon II, giant form I, or monstrous physique IV. You can use this ability for 1 minute per day, plus an additional minute for every two levels past 14th. This duration does not have to be consecutive, but must be spent in 1-minute increments.
