Mystic Mist

Area 
Produces a dense, opalescent fog that confuses anyone entering it; figures more than 2 yards away cannot be seen except by Mage Sight. Those who were within it when it was cast are immune to its effects; they can sense it as a dim shimmering, but it does not affect their vision or confuse them. Others must roll vs. (IQ + Magic Resistance) every second, or use Mage Sight, to avoid losing their way and walking in randomly chosen directions, unless they have a guide. 
Absolute Direction (M, P) avoids this problem. 
A Fright Check is also required of intruders first entering the mist, and again every 5 minutes. Anyone failing the first Fright Check will be very reluctant to enter! Dangerous animals simply avoid the mist, but suffer normal effects if for some reason they must enter it. 
Those “native” to the mist have a +1 to their defense rolls when attacked by interlopers, and interlopers have a -1 to their own defense rolls against “natives.” 
This spell is an excellent defense for a party camping in dangerous territory. 
The caster must cast Mystic Mist in an area centered on himself. The wider an area he can cover, the better!
