 Solid illusions are not all that solid, but they can be touched without disipating and hold all manner of nice details, such as \emph{smelling} right, or stopping smoke from blowing through them.  They are also far more realistic, and increase the \gls{tn} to see through the illusion by 2.
 
 These illusions have a Strength score equal to -6, plus the spell's level, plus the caster's Intelligence.
+They cannot carry anything which would give them Fatigue, so any illusion with a Strength score of -1 could use a dagger, but not a longsword.
 
 Solid illusions become an extension of the caster, and any caster can cast a spell \textit{through} the illusion, as if the illusion were the caster.  This might be used to cast an Invocation spell through a dragon illusion, or could employ Force to help an illusory creature lift a sword.
