The Ancient Seal is one of the many monster drops that can be acquired in the Frontier. They are typically acquired as a drop from the Bluemen.
In appearance, the Ancient Seal resembles a hexagon-shaped seal. The seal is made out of wood and stone and is engraved with an odd marking.
Like most monster drops, it is typically sold to selling vendors in sanctuaries. It does not have a relevant purpose in-game. As of late 1.10 (Fishing) Update, the Ancient Seal does not appear to be an exchangeable item during Slayer's Tasks.
- It is one of the few monster drops that were not heavily affected by the Otherworld Update and/or 1.10 (Fishing) Update.
- As of the 1.10 (Fishing) Update, it cannot be dropped from the Blueman's Chieftain.
