(Oh dear ^^ I didn't expect this would have caused so much trouble!<br/>Anyway, I'm pretty sure my interpretation is correct - it was based on the premise that I am a living target, but when affected by positive/negative energies, I react like an undead. Sssso:<br/>Thygor actually has the "Negative Energy Affinity" racial trait, which means: he IS living, but is affected from positive and negative energy as an Undead would be.<br/>Channel Energy allows the caster to either affect living targets (to heal/harm them according to the energy nature) or undead targets.<br/>Thygor's problem is that he IS a living target (as the trait itself specifies), but reacts as an undead target.<br/>So:<br/>-When positive energy is channeled to heal the living, he is damaged;<br/>-When positive energy is channeled to harm the undead, he is unaffected;<br/>-When negative energy is channeled to heal the undead, he is unaffected;<br/>-When negative energy is channeled to harm the living, he is healed.<br/>...Yup, it is a weird interaction, since it specifies that the character is considered as a target of one type but reacting as a target of the opposite type, while Channel energy requires to choose the targets according to the type  @_@<br/>Anyway, it is easier with spells and other effects: "Cure wounds" harms me, "Inflict wounds" heals me, since they're respectively based on positive and negative energy (even when it is not specified). The same with the high-level Heal and Harm.<br/><br/><blockquote><div><cite>ambrose-euanthe wrote:</cite>PS: I'm not sure why it shouldn't heal those we might be in battle with, actually, except that this seems ridiculous. Or maybe I'm only supposed to use it for out of combat healing?</div></blockquote><br/>I don't know - it seems it actually affects every creature of the chosen type (living or undead) in the area, so it should heal both allies and enemies indiscriminately. I think there's a specific feat (EDIT - the one Jermayan pointed out) to exclude targets from the channeling effect, specifically to prevent it from healing your enemies ^^  )
