If you are having trouble with the Gazer in BBI, the easiest way to get the Gazer to drop down so you can damage it, is attack the tentacles that come up from the ground until the main big one comes up. The one that glows orange under you before it reaches up, if you can time it right you can get this thing to reach up underneath the Gazer and it will stun it enough for you to jump and cling onto the eye and attack it.
Thanks for the tip. I actually did get the tentacle to knock him down. The tome wouldn't hit him at all but I used them to damage the little stalks and that seemed to work pretty well at triggering the large tentacle.
