Azaleea said:IGN released videos for all the cores. It helped me get to 79. still missing 2. And of course they are the ones that are impossible to get in the warren and Core Foundry.
There are at least 82 in the game, excluding the possibly missing warren/core foundry ones (it could be that the counter is wrong, not the amount of cores)
Just sail over to the quicksand dungeon and pick up the two there and get your achievement, its not that difficult, and you don't do anything against the game to get there, its just jumping and flying
