Map bonus objectives

Hello

"You can acquire Shaper's Orbs by completing bonus objectives on specific maps spread around the Atlas."

What are these 'map bonus objectives'?
I have few maps T1 and T2, also with some quality improved.
I have finished few maps - but I still have 0/126 on Atlas.

How to get and complete 'bonus objectives'?

Thx

you need to craft the maps and run them. for tier 1-5 maps must be magic to get the bonus, tier 6-10 rare, tier 11-16 rare and corrupted.

shaper orbs only drop from the maps with the purple circle arround them (upon finishing the objective)

If you hit "G" to open the Atlas and hover over each map node, they will tell you what the bonus objective is for that map and whether you've completed it or not, but yeah, Clownkrieger is right.

1-5 magic
6-10 rare
11+ rare + corrupt
Uniques just complete as is. <-- addition to his or her list

And maps with a purple ring drop Shaper Orbs.

Thx.

It should be somewhere on wiki....or I am missing something...

What maps drop them: http://pathofexile.gamepedia.com/Shaper's_Orb

Detailed Atlas Mechanics found here tells about the bonus objectives. I'm not sure wiki is completely necessary for this as all you have to do is hit "G" in game and hover over the maps on the Atlas to find this information. But, being there is information for everything else on wiki, I don't see it as being unreasonable to find in one. The information could easily be added to the first link.

Only new unique maps drop shaper's orb when you complete them. You can still run old unique map to unlock it in atlas.

I have not noticed those maps in corner of atlas....
I need to get better glasses... :)

Thx for help
