Lucid Channeling

 
Prerequisite(s): Good Alignment, Int 13+, Wis 13+, Cha 13+
 
Benefit: When channeling a celestial (see page 102 ECS), you allow it complete access. The celestial uses its own Int, Wis and Cha, just as a possessing Demon does. Both you and the channeled celestial have full access to each others thoughts, as the detect thoughts spell, except that each can automatically read the others surface thoughts. Each can draw on the other's memories, but only if given permission to do so. The channeled celestial and host can share spells and effects just as a spellcaster and familiar do.
