This dino lacks any real utility due to the fact that it is a boss and therefore cannot be tamed.... But it drops the highest amount of element out of the four bosses if that can be seen as a utility of sorts

FYI the fire damage is percent of health based, its not reduced by armor or levelling health. In fact, the lower the health the better tbh. Because if you have a massive health pool your pig will struggle with all the health to recover, while if you only level melee the damage done by the fire can be more easily dealt with, and youre less likely to lose rexes/therizins.

I wonder is this a vanilla boss???
