About:
Boss Refreshed is a texture pack for most recent versions of Minecraft that remakes all 4 Vanilla bosses into more ferocious, epic, and terrifying versions for people who are seeking something different without departing too far from the original Vanilla style.
Attention:
While Optifine is the more popular method of using CEM Packs, I would personally advise using Entity Model Features. The reason is that for Boss Refreshed specifically, the Ender Dragon has no animations on Optifine. Why this is I have no idea.
