Quick update for the Legacy version, found a couple buggos.
Changed the default crafting recipe for this version,
removed uncesessary settings in the config,
and removed all the 1.13 features i was working on which had not been implemented when i ported the plugin to 1.8
And finally added an option in the config to allow players to throw regular fire charges. "Material.FIREBALL" in 1.8 - 1.12
That should be about it!
NOTE: i will no longer be giving support for this version, if you find a bug, feel free to report it and i may get an update out for it in the future,however, i am not prioritizing Legacy versions of spigot, and will only continue to actively update and improve ThrowableFireballs for the latest Spigot Build.
