Usage:
cast vision <target>
The 'vision' spell restores temporary vision loss from dust, chemical
attacks or bright lights. A successful vision spell will protect the
target from being blinded for a short duration afterwards.
The lingering effects do not protect from eyebite.
This spell will also reduce the duration of the 'eyebite' curse, and
costs less mana 'lift curse'.
