Missing maven voidstone

Hi,

I have killed Maven many times. But i am missing the voidstone.
I have talked to Kirac, nothing there.

Can you help?

According to your Achievements, you have not defeated The Maven.

You may have completed lots of her Invitations, but that is not defeating her. Crescent Splinters combined (10) will give you the Maven fight.

As noted above, your Achivements indicate you have never fought the Maven.

To make the difference clear;

You can invite the Maven to watch you fight a boss, adding an added mechanic to that fight, and letting her collect a copy of that boss.

Then you fight these collected bosses for her amusement. When you do this with 10 Bosses in the pool using an Invitation, you can get 1 OR 2 Cresent Splinters.

Enough Splinters (ten of them) turn into a single attempt to fight the Maven herself. This step is the actual Maven fight that unlocks the Voidstone

As such every fight with the Maven requires TEN audience fights with TEN bosses each, and thus roughly 100 Maps.
