Well-Connected is a Path of Exile achievement.
Omen of Connections: Will be Consumed when you use an Orb of Fusing on an item to ensure maximum Links
An Orb of Fusing is a currency item that can be used to re-roll the links between sockets on a weapon or piece of armour. The colour and number of sockets remain unchanged.
As the following example shown, I use Orb of Fusing to re-roll the links of a Highborn Bow. At last, I get a six-linked item and complete the Well Connected achievement.
