I made an endgame overhaul / adventure mod that throws balance out entirely — roast it and tell me what to add and how to improve it

I've been working on an endgame overhaul mod called Titan Bosses & Endgame Overhaul — built around the idea that late-game Minecraft should feel like you're crossing into territory the game wasn't designed for you to reach.

The progression takes you from standard survival into crafting materials that shouldn't exist, facing encounters that don't scale to you, and eventually wielding the only weapon capable of ending things that were designed to be unbeatable.

What the mod adds:

• 11 Titan-class bosses tiered from Multiversal to Outerversal — each one a step further outside what normal combat was built to handle
• The Crucible — the singular weapon calibrated to damage entities that ignore everything else
• The Praetor Suit — armour that doesn't reduce damage. It removes death as a mechanic entirely
• A final boss The Old One, (based on the lost infinity stones final boss) that cannot be /kill'd, cannot be cheesed(i think), and recontextualizes everything that came before it as prologue

The mod isn't built around balance. It's built around the feeling of pushing past every ceiling the game has — and finding out what's on the other side.

Would love feedback from people who've built or played heavily modded endgame content — what's missing, what could be deeper, what would make encounters like this feel truly earned?
