How to Use
To play a full skyblock with the provided changes, players will need access to a water source (Conjure Water), Crush, and a Casting Item (book, wand, etc.). Glyphs can be configured in the Ars Nouveau configs.
Ideas for Use
- Reduce player Regen and grant an early Ritual of Mana Regeneration. This forces the player to build a regeneration network early, or play around a central point to cast spells.
- Provide the Ritual of Sedimentation along with Crush and Conjure Water (set to Tier 1) for generating ores.
- Start the player on a small patch of land with a brazier and Tablet of Conjure Starter Island. You can change the starting structure with a datapack, or use the provided one with the above changes.
- Use Ars Nouveau's Conjure Island rituals to encourage the player to build grassy sky islands and biomes.
