I got great news for those who still on minecraft version 1.9 because we now have a great rpg map called Herobrines Nemesis.
This map is not related to Herobrines series by Hypixel but the creator did say he tried to make it as a good sequel within the standard of previous Herobrines.
Client Version: 1.9.4
Let see, it has 4 custom boss fights, custom npc, custom items, custom sound and a great looking scenery.
From the preview image it has the RPG feeling I’ve been looking for.
There’s also a lot of side quest, mini games, secret and loot chest. I think it’s worth to check out
