Get a Fire-Wyvern level up stamina, and melee, you'll need it and a whole lot of patience, spam the fire breath and fly around the Dreadnoughtus biting in between fire breaths and when you've run out of stam and are forced to sit on the floor a bit, continue this process for the rest of day and you might end up killing him and getting a bit of meat, this job takes forever on a lvl 5! and you don't even get all that much food as you'd except and hope for, so no this is not worth it, but u have wasted you're time! Please like, and if you don't feel like it don't like and scroll on, the point is Please Don't Dis-Like!🥺(I hate that emoji but it's the only one that looks sad, puppy eyeing, and begging for mercy,)
