Splicer Augment: Tremorsense

The creature gains tremorsense out to 15 feet. If it already has tremorsense, the range is increased by 15 feet up to a maximum of 30 feet. A creature with tremorsense can detect and pinpoint the origin of vibrations within a specific radius, provided that the monster and the source of the vibrations are in contact with the same ground or substance. Tremorsense can't be used to detect flying or incorporeal creatures.
