Cinematic boss titles: when any boss appears, black bars slide in and its name comes up in big letters - and a victory card plays when you win. Works with modded and server bosses. Client-side.
Level up effects in the world around you: a pillar of light and a ring on the ground for level ups, advancements, first diamonds and FTB Quests. Small for everyday moments, epic for milestones. Client-side.
