As per the title. It would be useful for players to have a way to penalize the spot/search skills of monsters, which would aid in stealth. IIRC, cloud spells generate agro for the caster just like other spells, right? I'd like to suggest that they be changed to not do so. After all, it's not like a guy in a Fog Cloud or Sleet Storm spell can see much, much less figure out who cast the spell. These changes would only apply to cloud spells that do not do HP damage.
