New Feature/items

Riftbound Headsman

• Thrown Rift Anchor on a natural Flux Rift summons the Headsman. The rift stays open until the boss is slain
• Immune until "Plasma Disrupted" (Plasma Disruptor or Proximity Defense Laser)
• Takes 20% damage from explosions (TNT, landmines, creepers)
• Opening 3s invulnerability, then a roar teleport into a neighboring chunk
• Skills:
  • Melee slash = frontal cone (5.5 blocks, 100% damage)
  • Overhead = frontal cone (6 blocks, 125% damage)
  • Spin = full circle (5.5 blocks, 3 hits at 70% damage, knockback). Phase 2 only
  • Slam = full circle (6.5 blocks, 130% damage, knockback) plus shockwave (9 blocks, 85% damage, stronger knockback)
  • Roar = if the player is on the ground and boss cannot reach them, teleport with a flux cloud at the old and new position. If the player is in the air and boss cannot reach them, apply Grounded for 10s (blocks flight, 15s cooldown)
  • Summon = summons 2-4 rift minion
• AoE attacks break non-vanilla BlockEntities in the hit shape (player Y ±1). "minecraft" blocks and "wither_immune" stay. Drops are kept. Player damage is not blocked by those machines
• Cannot leave an 8-chunk leash from the rift.
• Leaving the leash sends him back to the rift. He resets to phase 1 at full HP, drops Plasma Disrupted, and is invulnerable until he arrives. The encounter timer keeps running
• Kill window is configurable ("headsmanEncounterSeconds", default 120s, shown on the boss bar). Timeout sucks the boss back into the rift
• Stats scale with rift flux. Base stats at 0.50 Φ/s, up to "headsmanMaxStrengthBonusPercent" at 5.00 (default 75, max 300)
• Player XP scales with flux from 180 to 1000. Warrior kill XP is a flat 150
• Enrages below 50% HP
• Drops an Aether Splinter

Aether Splinter / Aether Glass

• Four splinters assemble into 8 Aether Glass
• Aether Glass is blast-proof including Wither, emits light, breaks by hand, and always drops
• Stops a Flux Reactor meltdown. Terrain and kills stay on the inside. Entities outside get pressure knockback
• Six Aether Glass craft into 16 Aether Glass Panes
• Same light, blast, smash, and meltdown shield as Aether Glass
• Laser fence and Defense Unit beams pass through full Aether Glass, not Aether Glass Panes. The fence only amplifies with glass directly in front of both posts
• After the first glass crossing the beam deals 2× damage and applies Plasma Disrupted

Aether Casing

• Crafted from a Phase Core surrounded by 8 Aether Glass
• Used in the Flux Reactor assembly

Phase Gate

• Assembled from Aether Casing, Phase Core, Energy Containment Cell, and a Contained Rift at 5.00 Φ/s
• Open cost is 32 FE per chunk from the origin Access Terminal (min 1000 FE, max 25 MFE). Cross-dimension opens cost 500 kFE
• Stays open at 10 mB/t Rift Ichor from the origin gate. Closes when the tank runs out
• Cannot open unless the origin gate has at least 10 mB

Adaptive Vision

• While enabled, shows hostile mob HP ("current/max") and Flux Rift strength above the target
  

Changes

Rift Anchor

• No longer collapses a Flux Rift on hit. Capture and the Contained Rift drop happen only if the Headsman is slain

Worker release

• Releasing a worker no longer closes nearby Flux Rifts

Flux Reactor

• Recipe uses Aether Casing instead of Machine Casing

Automatic Door

• Recipe uses Aether Glass instead of vanilla glass
• Stops a Flux Reactor meltdown the same way as Aether Glass, open or closed
• Blast-proof including Wither

Flux Rifts

• Natural rifts no longer generate over open water
• Failed Headsman attempts lower the rift's flux toward 0.50 and shrink it. Attempts per tier are configurable (default 3). The last failure destroys the rift with a burst and gas cloud

Landmine

• Landmines arm only after linking to an access terminal
• Max link range is configurable ("maxLinkDistance", default 128 blocks, same dimension)
• Detonation requires a valid linked terminal in range. Missing or out-of-range terminals unlink the mine

Assembly Machine

• Assembly Machine no longer has an internal energy buffer. Crafting energy is billed through the Access Terminal

Modification Station

• Module and armor slots lock while installing
• Install can be cancelled from the GUI even without terminal energy

Proximity Defense Laser Module

• Hits apply Plasma Disrupted to rift monsters and rift bosses

Flux Insulation Module

• Drains 100 FE/t at 5 Φ/s and above, split across installed pieces. Lower flux drains less. A piece with no energy does not insulate
  

Fixes

Access Terminal / network machines

• Linked machines (except Storage Module) keep GUI access when the terminal has a card but no energy
• Fabricator and Processing Interface clear production queues on power loss
• Assembly Machine, Ice Maker, Modification Station, Electric Furnace and Research Terminal pause work and resume after power returns
• Miner Drone returns to dock on power loss, waits 10s of stable power, then resumes from the last completed dig or fill

Rift Creeper

• Deflates again if the fuse is cancelled
