- Will die if observed by specific individuals or individuals from a particular group (or maybe anyone at all!)
- Will die if anyone sees a certain part of them (eg, their back)
- Must always accept a challenge, provided the prizes for winning are appropriate (maybe they will demand to get your soul if you lose)
- When shapeshifting, must always have some indication of their true form present, never being able to fully hide their real self
- Can only cause harm if you look at them
- Can only cause harm if you look at/observe a specific object
- Can only cause harm if they trick you into verbally agreeing to it
- Can only cause harm if you try to cause them harm first
- Can only cause harm if you try to learn information about them
- Can only cause harm if you perform a specific innocuous action or say a specific phrase (candlejack candleja-)
- Cannot cross flowing liquids (may be specific to the liquid type, or maybe just generic flows)
- Cannot cross/enter unmoving liquids
- Cannot touch certain objects or object types without certain conditions being fulfilled; maybe they will be held back by a forcefield, or the object will pass through their body as if they were a ghost
- Must/will kill the first person they observe upon being woken up
- Invisible creatures/ghosts may be unable to harm anyone who can't see them
- Invisible creatures/ghosts may be unable to harm anyone who they don't
know can see them, so victims must be sufficiently non-stoic/prone to reacting to the presence of these ghosts to be attacked
- Every utterance must be a lie (should be interesting)
This statement is false!
- Can only advance toward someone whose back is turned / cannot move while being observed (should the overseer count as an observer?)
Hmm, tricky, on the one hand it would dampen the impact of the effect to see them move as an overseer, and it would also possibly be a problem computation-wise to calculate whether individual creatures are observing them (there must be a reason we don't have fog of war for areas without dwarves in them, right?).
But on the other hand there's no point to them at all in fort mode if the overseer stops them moving, as well as immersion breaking...
