Current author release
The author’s CurseForge listing shows Wellspring 1.1.1-alpha for Minecraft 26.1.2 with NeoForge. It marks client and server support, but the public listing does not establish a complete dependency matrix. Check the exact file page before installing.
How its portal differs
The author says players defeat a Warden to obtain a key, clear vines from the Ancient City central portal, and use the key on Reinforced Deepslate. The author warns that this entry method may change. Mielon’s Singer and eight-note melody are a different mod’s mechanics.
Alpha caution
The project description calls this a very early alpha and says many features may change. Use a separate profile and backed-up test world. The author expects to revise the interpretation as more official Dungeons II material becomes available.
Latest author file and changelog
The author-uploaded 1.1.1-alpha file for Minecraft 26.1.2 NeoForge includes a changelog note that world creation getting paused was fixed. Use the exact CurseForge file page to check any later version. The listing does not establish a complete dependency matrix, so we do not infer one. We do not mirror the .jar.
