From LSWiki

Everything here is a bit out of date and a mix of current and previous versions of the apagion.

You experience feelings of vibrancy, warmth, happiness, and sensitivity.
You experience visions of bright luminescence.
You experience astral visions of flows of extropic energy.

Bonding Requirements

You sense an initial eagerness quickly followed by disappointment from the glow,
like it was expecting to find an emotional depth to you that isn't there.

It is likely that some amount of empathy is required for bonding this familiar, or possibly introspection or discipline.

Known Abilities

The humble apagion is a small glowing creature composed of pure dweomer. Although it is not physically powerful or tough, it is hard to hit, extremely resistant to mundane damage, and deals extropy damage in melee. It can fly very quickly and is intangible. It is ametabolic, and cannot eat or drink. It also emits light.

The apagion appears to be able to see only by paravision, and thus cannot obtain exploration experience while being carried.

Telesmatic aura

The aura granted to the apagion by the empathic bond enables a special attack based on the consort's affinities:

A blast of chaos explodes from Aleph's body toward Tessit, but he dodges.

Energy Renegeration

This appears to begin at Very Healthy. While in the presence of the familiar, the consort gains a general regeneration ability that charges spirtual energy, endurance, and chakras at the cost of extropic energy.

Attribute Modifications

A large bonus to Willpower, Charisma and Perception, and a moderate bonus to Intelligence.

Skill Effects

Charms

• Standard Charms
• Convert (Extropic Energy)

Additional Bonuses and Powers

Traits granted

Close to the beginning of the bond, the consort gains the Regrowth trait, which improves with bond strength at the rate of about 1/5%.
