The caster summons a storm.  This spell must be cast outdoors.  The storm will be a dust storm or sandstorm in an arid region, or a rainstorm otherwise.  The storm is not dangerous to structures or living things, but will impart Concealment 1 to all creatures within it.  This increases to Concealment 2 if it the [[unbound:actions:sustain_a_spell|Spell is Sustained]], and to Concealment 3 if it is Sustained again.

When the caster ceases to sustain the spell, the storm begins to subside.  At the beginning of each round, roll a d10.  If the result comes up showing a 1, the storm will lose one level of Concealment.  When it has lost all levels of Concealment, the storm ends.
