Ars Caelum

The mod adds rituals that create islands and terrain. Conjure Starter Island builds a starting island from a configurable structure file, and map authors can let players place it with a brazier. Other rituals produce islands with blazing, vexing, flourishing or cascading themes, some holding archwood and resources that are otherwise hard to obtain. Milestone progressions can gate these islands, and an addon adds skyblock compatibility.

Further rituals cover cobblestone water sources through Ritual Sedimentation, a Deep Dark island that converts its area to sculk, an island with an end portal, and an amethyst geode. Ritual Elder Summon calls waves of augmented Guardians and Elder Guardians, while Ritual Mana Regeneration gives nearby players mana regeneration level 1. Ars Caelum is published for Forge and NeoForge, with files for 1.19.2 and 1.20.1, and it runs on client and server. The latest file is 1.20.1-2.0.1, dated 2024-03-10. The code is public, and the mod is licensed as All rights reserved, so it is not open source.
