Summoner (Unchained) › Greater Aspect
Tremorsense (Ex)
Source: Pathfinder Unchained, p. 37
The eidolon becomes attuned to vibrations in the ground, gaining tremorsense with a range of 30 feet. This works like the blindsense evolution, but only if both the eidolon and the creature to be pinpointed are in contact with the ground. Requirements: Summoner level 7th.
