Anchag is spawned by killing all 12 enemies (even the docile Wild Onions) in Karydine Glacier. Contrary to popular belief, the player does not need to leave and re-enter the area to spawn Anchag, simply killing all will spawn it at the center-south region of Karydine Glacier. It appears with the Trophy Rare Game Ancbolder if the player has started the Hunt Club quest. Though the Ancbolder can only be felled once, the Anchag will appear every time the proper conditions are met, but only once per visit to the Paramina Rift. Anchag can be farmed for Damascus Steel.
Anchag, along with Bluesang, make up a pair of only Rare Game that derive from the same kind of enemy, namely a Dullahan. Additionally, both Rare Game can be robbed of the Damascus Steel to make the Gemsteel for the Tournesol.
