We are now using a server resource pack to allow for better custom items, mobs, blocks, etc.
Not using the pack causes certain features to not function.

If you don’t want to wait for the pack to load every time you join, you can download it separately and set server resource pack to disabled in your server list.

The Elytra no longer supports Mending nor Photosynthesis, requiring manual repair with Phantom Membranes. However, you can repair them infinitely due to the anvil changes.

Elytras have also lost their ability to be boosted with Firework Rockets.

Alternative flight options: Riptide Tridents, Lunge Spears, Wind Charges, and most notably — Blasting Crossbows.

The vanilla minecart improvements datapack has been added. Minecarts on powered rails are now comparable to the speed of ice boating.

The vast majority of vanilla mobs have had some of their stats buffed to increase difficulty and keep up with all the custom gear.

Although this change mostly targets hostile mobs, some helpful mobs like Happy Ghasts have had their stats increased too.

New variant of mobs with only around 1% chance of spawning. They appear with purple particles surrounding them and are much stronger compared to regular mobs. They also cannot be put in boats, but also drop more items and exponentially more XP.

Some enchantments have had their compatibility lists changed. Most noticeable: Mending and Infinity are no longer incompatible, and Tridents now support Sharpness.

A large amount of new enchantments have been added, scattered through nearly all custom structures throughout the server.

Anvils now no longer track the number of times an item was used on them. This makes enchanting, repairing and renaming items much easier.

When dying to players, XP now drops approximately 50% of held Experience Points and goes beyond Experience Level 7.
(This is buggy on higher levels and drops less than it should)

Density has had its damage per block fallen decreased.
Breach has been changed to have less armor piercing.

The Mace also has the same charge time requirement that the Spear has, meaning you need the attack charge to be full to be able to attack, thus making landing Mace hits much harder, allowing us to not have to nerf it’s damage as hard.
