Bonding Requirements

Some amount of both discipline and empathy seems to be required.

I needed about 120 skill points in Empathy, while needing about 80 in Discipline. Empathy is the main concern. - Cinna, 3:28 PM PST, 12-24-12

Seems somewhat less than that. Was able to bond with 105 empathy and 75 discipline.

Failure Message

You sense a lack of regard from the white-feathered female swan, and dimly feel that she
considers you to be insufficiently serious about kindness.

• Lightgarb, the ability to encase one's body in a protective sheath of light. The light will attempt to absorb damage by drawing on one's radiant energy.

• The ability to become one with your familiar.

At "Very Deep"

• Visual Displacement the ability to make it appear as though one is standing several dimins from one's actual location. (Illusion, probably Agility, and one other skill)

At "Intimate"

• Summon a major light amalgamal, a much more powerful version of the light spirit

At "Complete"

• The ability to become Invisible

Additional Abilities

Swan familiars open and charge the Anahata chakra and Muladhara chakra periodically and provide several special sword attacks which utilize radiant energy, and one which is usable without swords.

Attack                     Activity Cost

Crescent                   8 (Based on your sword speed)
Lux Veritas                14    
Solar Coil                 12 (Also based on your sword speed)
Stellar Twist              12 (Again, based on sword speed)

The Crescent attack (at somewhat frail) is a photonic-based attack that adds Light Affinity, Lumiturgy, Wyrding to attacks and Light Affinity & Wyrding to damage. It also requires a normal-sized sword to use.

Lux Veritas (at robust) channels the light of truth through your sword strike. This attack cannot miss. (Seems to have a combined ray of intense light and a shaft of true sunlight.)

Stellar Twist and Solar Coil (at nearly complete) use Light affinity, Lumiturgy, Telesmatic weapon and more. Stellar Twist may only be used at night and Solar Coil during the day.

Traits Granted

Grants Ambidexterity.

Around 1/3 way in resilient bond, diet changes to photovore.
