#Not in Adventurer's League.

This is from the Tomb of Annihilation Primer, found here. This document is a guide put out by Wizards of the Coast for players and DM intending to take part in Tomb of Annihilation, and lays down the rules of play for this adventure. Do note that this quote is from the DM-only section of that document. Proceed with caution if you're a player.

Some characters may be tempted to claim ownership of the Ring of Winter and Artus’s prized dagger, Bookmark. As Artus is completely unwilling to surrender these items voluntarily, characters must use force or magic to obtain them. Given Artus’s importance in Faerûn, this spells the end of an adventuring hero’s career.

Characters involved in facilitating the theft of Bookmark or the Ring of Winter are permanently and irrevocably retired from Adventurers League play—some crimes are beyond forgiveness.

If you take it from him OR help someone else take it from him, your character is immediately and permanently barred from all AL play.
