Heh. It's one of those abilities, which really could have used a bit more explanation.
Well, here's what I do....
I see the shadowdancer's ability as a mythical connection to the plane of shadows (or just a mythical connection to "shadows" in general). When using HiPS "shadow stuff" is drawn from the plane (or simply created out of "shadow") via the connection to a natural shadow within reach to hide the shadowdancer. This "shadow stuff" lets the shadowdancer apply the Hide skill (it grants concealment, or whatever, this is not really important other than, that it is that magical part of the ability, which creates what is necessary to actually hide, and what the shadowdancer does not need otherwise). It's similar, but not equal to
Invisibility.
- The shadowdancer can hide on a spot in the open, if there is a shadow within 10 ft. (it does not have to be big enough to actually hide the shadowdancer, but must be reasonable large... like a square-foot or whatever). This looks like the shadowdancer fades into shadow and vanish.
- The shadowdancer can use Hide while moving as normal (with the appropriate penalties, see the Hide skill), as long as there is
always a shadow within 10 ft.
-
True Seeing reveals the shadowdancer, since the HiPS ability is supernatural and therefore magical in nature. Only by using the Hide skill normally with natural cover or physical concealment (darkness does not suffice) allows to trump
True Seeing.
- When attacking (in an obvious way), the shadowdancer is also revealed as normal when hiding, there is no way to avoid this, except using the sniping rules. However, the shadowdancer can attack (standard action) and then hide again (move action (see below), with a -20 penalty - changed my opinion here, see
THIS thread for explanation), which is obviously superior to using the sniping rules, since movement is allowed in addition to the attack (with sniping the move action is spent without getting to move), because the shadowdancer can use the Hide skill under observation.
Also you always need to spend at least a move action to hide. This can be combined with normal movement, that is you can move up to your speed and hide with one move action (penalties apply, if you move more than half your speed). Hiding itself is not an action, but part of the move action.
I do not allow (except for extremely rare and obscure circumstances) hiding as part of an attack, full-attack or charge action.
