This spell summons into the 
caster's hand a small crystalline sphere filled with a gray, 
hazy mass.  The smoke sphere can be thrown as far as 60 
feet away from the caster as a grenade-like missile.  The 
sphere shatters when it hits, filling an AREA 10 feet in radius 
with harsh, irritating smoke.  Unless a SAVE vs. poison 
is made, all creatures within the AREA of effect will 
suffer a fit of coughing, gasping and choking for 1d4 + 1 
rounds.  The affected creatures attack and make saves 
with a -2 penalty until the fit passes, and any spell 
with a verbal component has a 30% chance of failure when 
CAST by a coughing spellcaster.  The smoke cloud disperses 
and becomes harmless after 1 round.  The sphere must be 
used within 3 rounds of casting or the substance 
becomes inert and useless, and the crystal sphere disintegrates.  
If the smoke sphere is shattered before it is thrown, 
the smoke cloud will affect the caster. 

MC: Charred stick or piece of charcoal and a  small, hollow 
glass ball.
