The bellator ring is one of four ancient rings which currently boasts the highest slash attack bonus of any ring, surpassing the imbued warrior ring by +12. The ring requires players to have killed the Whisperer at least once to wear, which is done during Desert Treasure II - The Fallen Empire; attempting to wear it otherwise will result in the message The ring slips off your finger. The power within it seems unfamiliar.
The ring requires level 90 Magic and 80 Crafting to create (both being boostable), as well as having learnt how to combine Fremennik ring icons with ancient vestiges via Peer the Seer.
Despite the poll blog and newspost stating the bellator ring requires full completion of Desert Treasure II to wear, this is not the case in-game, and players need only to have obtained one kill count of the Whisperer to wear it.
