It took me about 10-15 runs to get the drop, although I’ve heard of players getting lucky and having it drop on their first few runs. To get Gnawing Hunger you’ll want to defeat The Likeness of Oryx and you’ll have a chance for a drop once he’s been defeated. Gnawing Hunger is a Tier III exclusive weapon, so the best bet is to unlock The Reckoning and upgrade to Tier III as soon as you can. These bosses rotate daily, so if it’s not the one you want today then it will be tomorrow. There are 2 bosses, either Swords or the Likeness of Oryx. There are 3 tiers of The Reckoning, and for Gnawing Hunger, you’re going to want to run Tier 3 as this is a specific loot drop from one of the bosses called The Likeness of Oryx. Once you have access to Gambit Prime you’ll have to work through some bounties to upgrade the Synthesizer and this is key to accessing the higher Tiers of The Reckoning. This will take you through the mechanics of Gambit Prime and The Reckoning. He’ll give you a quest called ‘Gambit, in it’s Prime’. Have a chat with the Drifter in the Annex in the Tower. To get this weapon you’ll need to do a short quest to unlock The Reckoning. Gnawing Hunger is an Auto Rifle that was introduced during Season 6 of Destiny 2.
