Wild Surge
The pain wilder draws strength from pain but can only wild surge if she is experiencing physical pain. The pain wilder must have suffered hit point damage within a number of rounds equal to the number of points in her wild surge.
If the wilder is injured while manifesting a power, such as by an attack of opportunity, she may use that damage to qualify to activate the wild surge on the power being manifested, as long as she makes a successful Concentration check as normal. Because a pain wilder embraces pain, it acts as a focus for her manifesting ability, not as a distraction. If the pain wilder is injured while manifesting a power, the number of points of damage are halved to determine the DC of the Concentration check.
If a pain wilder is taking continuous damage, she does not need to make a Concentration check for the continuous damage.
Psychic Enervation
When a pain wilder suffers psychic enervation, she is sickened until the end of her next turn and loses a number of power points equal to her normal manifester level (the increase in manifester level from her wild surge does not increase the number of power points lost).
Surge Bond
The pain wilder gains the precise harm ability, as follows:
Precise Harm (Ex)
The pain wilder can determine exactly how much damage she wishes to inflict on a willing or helpless subject. This ability cannot be used on creatures that are unwilling or not helpless. Whenever the wilder has a minimum to maximum amount of damage to inflict – such as with a weapon – they can choose the amount of damage they deliver within those limits, including foregoing Strength or other bonuses to damage.
For example, if a pain wilder with a Strength of 12 and a dagger wishes to inflict damage on a target that is willing or helpless, she could inflict any amount of damage between 1 hit point and 5 hit points.
This can make the pain wilder an expert surgeon or an expert torturer. As such, Heal is added as a class skill for pain wilders, and they gain a +4 competence bonus on any use of the skill that involves surgery. Likewise, if a pain wilder makes any use of Intimidate that involves inflicting pain on the target, she also gains a +4 competence bonus on the check. The pain wilder’s ability to choose how much damage is inflicted applies in these circumstances.
For example, a pain wilder attempting to remove a barbed sting that will inflict 1d6 damage on withdrawal would gain a +4 advantage to her Heal check to withdraw it, and could choose how much damage to inflict if successful or not.
