Tremorsense

This bug may effectively “see” when in contact with the ground or a wall, or within a liquid. Airborne bugs are harder to pinpoint, and this bug receives -2 dice penalty on attack rolls made to hit them when using this sense alone. Bugs on the other side of solid surfaces can be detected unless they remain perfectly still.

This sense is not affected by darkness, though especially noisy things nearby may reduce this sense’s range as darkness would for sight.
