It seems that if you kill one of the Talos of Gaia hourly bosses and recieve the [Agitated Shard] from the [Genizah of …] reward container, you are not awarded the Talos of Gaia Lore #11, even if this is the first “angry” Shard you recieve. All the other “angry” Shards seem to award that lore automatically.
I got lucky and had a Destructive as my first, so I got the lore, but in a total of 60+ Talos kills, I got 1 Destructive and 2 Agitated Shards. Others have had even worse luck and are still hoping for a shard that isn’t Agitated.
