I could support blindsense, as long as it was limited to the tentacles like the scent.
Rename "olfactory tentacles" to "sensory tentacles", and add blindsense 150 ft. to the writeup?
Giving it blindsense is OK by me, but I was thinking more 40 ft. or 60 ft. blindsight, one the idea that it "feels" the location of nearby creatures.
e.g...
Sensory Tentacles (Ex): A tirichik's tentacles give the creature 40 ft. range blinsight, and increase the range of its scent ability fivefold, allowing it to detect creatures within 150 ft. (300 ft. if the creature is upwind, 75 ft. if downwind). If one tentacle is severed the tirichik's scent range is reduced to 60 ft. and its blinsight is reduced to 20 ft., if both tentacles are severed its scent range is reduced to the standard 30 ft. and it loses its blinsight. Each tentacle gives a tirichik a +2 bonus on Survival checks to track by scent (+4 for both tentacles).
