so i just beat the game. was just wondering if the ocular served any purpose whatsoever. i got it after i killed baldy, and as soon as i entered the final chamber the game switched my helmet to ursugor's.
You need to use the Ocular to be able to see the Titans.. otherwise they're invisible. You'll notice in the opening cutscene that only the Inquisitor can see the Titan. I know you equip the helmet at the last bit of the game, but I guess the game still considers you're wearing the ocular underneath or something.
