<Guardian of Light and Dark>
Level 101 Heroic ^^^
Spawns when all other bosses are dead and circles clockwise around the central console.
Same mechanics as Luminox except at 81%, 61%, 41%, 21% will fire missiles. Also when getting ready to fire missiles you will see red text 'Luminox Prime rends the space around you, separating the light from the dark!' and orbs of light and dark will spawn all over the area and move back and forth. Touch the orbs of light to get a boost to in-combat run speed and avoid touching the orbs of dark to avoid a serious slowdown. Also between 60% and 41% it will fire lasers.
<Core Guardian>
Level 100 ^^^
Watch for the red text 'The Amalgam of Energy's core begins to overload! You can feel energy being ripped from the very air around you.'. Energy Globules will spawn around the edge of the room (4 at the 75% threshold, 6 at the 50% threshold and 8 at the 25% threshold) and slowly travel toward the boss and will heal it for 26.8 million HP for each one that makes it.
As long as any Energy Globules remain alive the Amalgam of Energy is immune to all damage.
<Core Guardian>
Level 100 Heroic ^^^
Move out of the way when you see the red text 'The Core Guardian plants its feet as it prepares to fire a volley of short-range missles' to avoid the barrages of manaetic missiles.
