Teleporter(Creative only), Healling, Healling doll, Ominous head, Grave axe, Grave sword;
NihilisticOrder will spawn in survival now;
You can meet HeadHunter in survival now(By challenging NihilisticWither).
There is a bug about OminousHead, Manifested as unable to render, but this does not make your game crash.
Tips : Right-click the WindSword to move forward a certain distance (about 7 blocks). There is no cooldown, but it will consume
 1 durability point (if enchanted with Enchantments: Unbreaking at any level above 0, durability will not be consumed).
The Potent Enchantment allows you to move even farther.
Wind Sword can craft using Wind Essence.
If there are any bugs, please report them in the mod comments or under my issues.
