Who is the caster for these sorts of abilities? Do they use the host's action?
For example, I'm looking at the Mind Leech in FF (p.217), and it's got a Psionics (Sp) block which lists suggestion, charm monster, and dominate person.
For example, there's a Mind Leech in a human's head, and a bugbear is nearby. The mind leech's charm monster effect is used. To whom is the target bugbear friendly?
- The human (and the target creature is unaware of the leech);
- The leech (and the target creature becomes aware of the leech);
- Both the human and the leech (somehow)?
