Gram

Unlock
Wolf of Nobina is a special boss that replaces the newbie ground boss if your party items includes a single runestone. It is tougher than a D3-10 boss. Defeating it for the first time awards you with Gram which is a unique named Tier 4 weapon which also starts out as SSS+20 (20). Defeating it multiple times provides no additional rewards.

Upgrading
Currently you cannot upgrade Gram, however with future Patreon Bosses added into the game, your Gram will be upgraded each new Patreon Boss you defeat.
