Suspicious Looking Tentacle
Calls upon a suspicious looking eye to provide light 'I know what you're thinking....'
A suspicious looking eye that provides light
10reading the eye
The pupil is the whole feature. It swivels toward whatever it has picked up and changes shape to tell you what kind of thing it found: wide for chests, pots and ore, narrow when something wants to kill you. Learn to glance at it and you get a warning before an enemy walks on screen and a nudge toward loot sitting behind a wall. It sparkles for buried metal, which is as close to a free ore detector as you will carry.
where it goes blind
Anything that is currently untargetable simply does not exist to it. Jellyfish, the granite constructs and biome mimics all sit in that state, so a calm eye in a granite cave tells you nothing at all. Treat the warning as a bonus rather than a radar you bet your life on.
against the other bright pets
The wisp keeps pace with you, snaps to your position when you outrun it, and can be pushed around the screen with your movement keys. This one only follows, and at wing speed it falls behind and leaves you lighting your own way. Take the eye for exploring, where the detection is worth more than the light keeping up, and the wisp for fights and long travel.
