This mod requires InsaneLib
This mod makes Wither and Ender Dragon harder by letting you summon a stronger version of them. Also makes the Elder Guardian's fight harder.
The difficulty will adapt based off the players around the boss.
- More health: they're bosses ... why can they go down with a few hits?
- New abilities: like Wither Charging or Dragon respawning crystals
- Minions: both Dragon and Wither have Minions
- Caged crystals: more cages will spawn around crystals, and some crystals will spawn inside towers
- Faster Acidballs and Skulls: dodging is harder
- Elder Guardian Fight's harder and with an actual reward!
- Many many bug fixes: Mojang no longer cares about the survival aspect of the game
- And much much more! This is only the tip of the
towericeberg.
