Tara's eyes light up, at the mention of possession. "Demons that can possess others are quite rare, so the actual mechanics of it are rather poorly documented, and it apparently varies from demon to demon." She does lean back a little, thinking for a few moments. "If their body is destroyed, that would mean they can only move from one body to another, but they'd need a fair amount of power, to jump from one body to another. It is far easier to return to one's own body, to rest, after possessing another. To jump directly from another's body, to a third? Mmm, they'd need to be strong. A new body, though? Yes... if it were completely soulless, it might serve as a proper vessel, and, at the very least, be easier to move into, as it would have no barriers to entry. Why the interest in possession, though?" she asks, cocking her head, curious.<br/><br/>(If Ruby wants to bluff her, the DC is going to be fairly low; Wis is not a commonly pumped stat for arcane casters. =P)
