Without Peer (Ex)
The Siberys wyrm does not spread his power among a great multitude, instead choosing to concentrate it into a select few individuals. When you spend an action point you may add the sum of all the dice rolled and add it to your d20 roll.
When you fail, the Siberys wyrm grants you power to try again. Once per round when you miss with an attack or fail a saving throw you gain 2 action points. If you voluntarily miss or fail a saving throw you do not gain the action points. These are temporary action points that last for 24 hours or until you use them.
Siberys Mastery (Sp)
The great sky dragon Siberys has blessed you, granting you enormous power. While others with true dragonmarks have a wider variety of abilities to command, your power runs deeper than any of theirs. You may use your Siberys Mark spell-like ability at-will. Your caster level for your Siberys Mark power is 10 + 1/2 your character level + your levels in the heir of siberys prestige class. If your power requires a saving throw the DC is 10 + 1/2 your character level + your charisma modifier.
One Source (Su)
The true power of the Siberys mark is not in its single ability, but in the power invested in the person. Each bearer of the Siberys mark learns to use that power in new and different ways. You can channel the raw power of the Siberys mark into positive or negative energy. As a standard action you can spend an action point and make a melee touch attack, choosing either to Heal or to Harm. If you channel positive energy you heal the target as per the Heal spell. Your caster level equals 10 + 1/2 your character level + your levels in the heir of siberys prestige class. Unlike the Heal spell this ability is uncapped and does not limit you to 150 points of damage healed.
If you channel negative energy you damage the target as per the Harm spell. Your caster level equals 10 + 1/2 your character level + your levels in the heir of siberys prestige class. Unlike the Harm spell this ability is uncapped and does not limit you to 150 points of damage dealt.
Perfect Imitation (Sp)
What you know isn't as limiting as people imagine. Though you bear a single Siberys mark you have learned to imitate the abilities of other marks. As a standard action you may spend an action point and use the Siberys Mark power of any other House. In addition the number of temporary action points you gain when you miss with an attack or fail a saving throw increases to 3.
Brillance of Siberys (Su)
A true unique creation, you have acheived the pinnacle of power with your Siberys mark. The boasts of others fall silent as you unleash the Siberys inside you, channeling its power to duplicate other dragonmark powers. As an immediate action you may spend an action point to duplicate the effect of a dragonmark power that was just used by another creature. You use your own caster level and saving throw DC to determine the effect.
