Detect Kraken

when you use this spell you can detect near by krakens for 1 round with in a 10 ft radius, but you have to cast as a ritual or use a 9th level slot to cast instantly, so as you cast the spell you character say "here kraken, kraken,kraken" for 20 min and when finished any krakens within 10 ft are reviled  only to the caster

(only works on land or in fresh waters)
