Gansk said:I am also getting slammed by this spell and consider it way too powerful. Here's the house rule I will be adopting in the next campaign:
Compare invisibility and silence - there are both glamers, a subset of the illusion school.
Invisibility creates an illusion to others that you are not there, but you really are there. You can see yourself, read scrolls, etc.
So why shouldn't the sound in a silenced area really exist, just not heard?
The implications are that all spellcasters in the area are deaf with a flat 20% SF chance. Language dependent, mind affecting spells are still negated, but sonic energy is not (you can still use protection from energy against sonic attacks).
You can still use the silence spell to sneak around with this interpretation.
I think this is a good compromise. I've always wondered why the Silence Illusion was a real effect and not an illusion.
