The Flail Head Cold is needed to create the Flail of Ages +3. but with one or two heads, you can forge an incomplete version of the Flail of Ages too. This head adds cold damage to the flails. This item appears in Baldur's Gate II: Shadows of Amn near the forge in the de'Arnise Keep.
|“||This is one of three flail heads belonging to Lord Arnise. Not all three heads are required to assemble the flail.||”|
