I've searched alot on the internet, but i've never found something to add another line above the player that shows player's health, i tried using scoreboards, and that seemed to be working in a test server, but not in my actual server (Cause Factions is using the scoreboard so it's breaking the plugin), is there another way?
There is nothing like that in 1.8.x. The bossbar how we know it for around 4 years. It was added in Minecraft 1.9. The "Bossbar" is just a fake EnderDragon in 1.8.x. You are really limited when using this old outdated ancient versions of Minecraft.
