You may have determined where to put all the orbs, but since the year is almost out, for others that come later and have the same question, here's the sequence:

Fire god orb = snake rune
Moss rat orb = death rune
Violet blast orb = gold rune
Blue moon orb = shield rune
White snow orb = mountain rune
