Sensing - Clairaudience
The caster can listen through any objects or structures that normally would baffle sound within a specific range. The range equals the area of effect (see the Magical Limits Table). The character can quickly scan the area of the spell's effect for conversation, unusual sounds, etc., but the actual area listened to, within his range, cannot be larger than a 20' radius. When zeroed in on, sounds from the area can be heard as if the caster was there himself. Any sound attack in the area has full effect on the character using this spell.
This spell requires a great deal of concentration. It can be used simultaneously only with similar Sensing spells.
This is the magical version of Clairaudience.
