The ultimate dragon mod

This is honestly the best dragon mod currently available for MC (Wyrmroost is a close second, but it doesn't really add proper dragon bosses in the way you'd expect from an epic fantasy). The models are great, and the combat is interesting (dragons have multiple attack movesets). Past mods have attempted and failed to add proper dragons to the game. But I&F? It's honestly scary meeting one when you're low level. I&F isn't the most stable mod, especially on older versions, but it's not bad enough to be game breaking. Just a little laggy.
Just remember to reduce dragon detection range or significantly reduce dragon den spawn rates, because those mother effers will tunnel to the surface and cross heaven and hell to chase your but down and roast it alive.
