Objects that enable one to use preternatural powers (such as magic, psionics, etc.), regardless if the foci itself is in anyway infused or interacts with the power or not.
Alternate names: Magic foci, Focal magic
Name variations: Power focus, Magic Focus
The first video game about Power foci was released in 1994.
Essentially a variation of innate magic, though commonly a component of verbal and/or somatic magic. Likely an error if used alone.
Some more traditional foci are in shape of wands or staves, though they've in modern times lost this function in most fiction (notable exception being Harry Potter series) and have become more like an amplifier rather than enabler.
There's two variations of this:
* Focus : without the foci the magic would be very vague and non-specific, utterly lacking precision. Such as trying to light a candle would blow up the whole room in flames.
* Amplifier : without the foci the magic is simply too weak to do anything else than affirm that magic is done, but not enough to actually Do anything with it.
If the foci is only a learning tool, then it's not part of this tag.
