How do you get the lustrous orb and adamant orb?

Answer:
Once you first exit Mt. Coronet and arrive in a snowy area (like you were going to go to spear pillar), go left (the only way to go at this point :) ) and go north (not up the steps) when the path turns. Head all the way north and rock climb up. Instead of going left (towards Spear Pillar), reenter Mt Coronet on the right. Go up the waterfall and you should see the orbs.
