ETG Crystal Engineering

Version 0.5.1 adds six artifacts, the Limited Parallel-Space Gun, and the Migration Pen.
- Wuhou: A blade that reveals vulnerable seams on living targets. Observe your target until red lines appear, then strike while the opening is visible.
- Kala: A celestial bow that generates its own arrows and kills creatures around the point of impact. Players are unaffected.
- Na Sumeru: A reusable vessel that stores terrain and structures as a miniature. Move and restore them while preserving container contents, block states, and structure orientation.
- Sacred Armor: A four-piece set with Netherite-level defense and Protection IV. Grants night vision, water breathing, full knockback resistance, fire and lava immunity, and water/lava walking. The complete set adds an angelic halo.
- Even If the Sun Sets Thrice: Prevents fatal damage three times per Overworld day while carried. Each activation grants three seconds of invulnerability.
- Draupnir: Stores one item and, after nine nights, returns the original along with eight identical copies.
- Limited Parallel-Space Gun: Opens portals to temporary parallel versions of the Overworld, Nether, and End, using the same world seed and generation settings.
- Migration Pen: A single-use tool for moving terrain and structures. Capture a selected area, carry it as a miniature, and restore it at a new location.
Please keep the following in mind:
- This version targets Minecraft 26.1.2 / NeoForge 26.1.2.76.
- Parallel-space sessions last 72,000 game ticks, approximately 60 minutes at normal speed. Players are returned when the session ends, and all three parallel dimensions are reset.
- Buildings and stored items left in parallel dimensions are cleared when the session ends. Do not use these dimensions for permanent storage.
- The Migration Pen is consumed only after a successful restoration. Failed attempts preserve both the pen and its stored terrain.
- Multiple copies of Even If the Sun Sets Thrice share the same daily allowance for each player. Carrying additional copies does not increase the number of protections.
All newly added items are currently available only through commands, and the in-game text has not yet been polished.
