Xaelion Additions — Changelog

2.0.0 (Seraveil 2.1.3 / Zephyra 1.0.3 / Xaelion 1.0.0)

Xaelion is complete. Every creature, boss, structure and block set from the Xaelion design is now in the game, and every model has been rebuilt with far more detail.

Vael'Zareth, Servant of Noctyra (boss). Offer an Abyssal Core at a Dark Ritual Altar to begin the ritual. Two waves of cult guardians come through the veil first, and the second brings the Abyssal Champion. Then the gate opens.

• Phase 1, ground commander:
  • Abyssal Cleave: an overhead chop with a shockwave.
  • Noctyra's Grasp: shadow hands that pin you in place.
  • Crimson Rupture: marked eruptions from the ground.
  • Legion of the Forsaken: summons cultists.
  • Blackened Oath: sacrifices his summons to heal.
  • Dark Dominion: spreads shadow zones.
  • Ruin Volley: three crimson bolts.
• Phase 2 (70%): his wings tear open and he takes to the air, with diving Wings of Ruin attacks.
• Phase 3 (35%): his armour fractures and the burning core is exposed (it takes extra damage). Noctyra's Judgment darkens the sky and sends out waves you have to find the gaps in.
• Cinematic death: he drops to a knee, his armour shatters off, and he collapses.
• Drops: Heart of Ruin, Ruin Armour Fragments, Noctyra's Sigil, sometimes the Ruinblade.

The Grand Ancient Dragon (boss). It sleeps in its lair. Sneak past, or offer Crystalline Dragonstone at the Ancient Dragon Altar to wake it. Using the altar where no dragon sleeps calls one down from the sky.

• Ground attacks: bite, tail swipe, Frostfire Breath, Crystal Tempest, Wingstorm, Draconic Roar and Frostfire Barrage.
• Flying attacks: strafing breath runs and Celestial Descent (it climbs high, then crashes down).
• Final phase: Dragon's Judgment.
• If left alone, it patrols its lair and goes back to sleep.
• Drops: Dragon Heart, Crystalline Horn, Dragon Scales, Dragonbone, sometimes the Dragonbone Greatsword.

New creatures

• Shadow Wraith:
  • Drains life and dashes through you.
  • Phases out of reality to escape, and shrieks to terrify.
• Moon Moth: a gentle night flyer. It orbits Seraveil's moon goddess form and heals her.
• Celestial Deer: shy and glowing. It bounds away in light and grazes in peace.
• Ruin Sentinel: an ancient guardian with a crushing fist, an arcane cannon, a ruin pulse, overdrive and a stone shield.
• Void Hound:
  • Hunts in packs, bites and pounces.
  • Blinks through shadow and howls to rally the pack.
• Yeti: heavy punches, snowball throws and a frost stomp.
• Alpha Yeti (mini-boss): ground pound, a leaping Avalanche Slam, Blizzard Roar, ice spikes and Frostbound Rage.
• Stone Golem: slams, boulder throws and earthquake stomps. It curls into a boulder to defend.
• Moss Golem: vine sweeps and root traps. It regenerates and raises a verdant shield.
• Ancient Golem (mini-boss):
  • Crush, Runic Beam, Seismic Rupture and Ancient Judgment.
  • A guardian barrier, and a core overload when it's weakened.
• Vikling Warrior: axe and round shield. Viklings fight in formation and raid at night.
• Vikling Chief (mini-boss):
  • Crushing axe blows and Shieldbreaker.
  • Warlord's Roar, and a war horn that calls the clan.
  • Berserker's Stand when it's weakened.
• Dragonborn:
  • Ivory: guards dragon places and trades its wares for 8 emeralds.
  • Obsidian: shares the lore of the dragons.
  • Crimson: hostile, breathes fire and charges.

Structures (found naturally in fitting biomes):

• The Forbidden City, with the Dark Ritual Altar on its ziggurat.
• Cultist Temples, guarded by the Champion.
• The Dragon Lair, with a sleeping dragon and its altar.
• Vikling Outposts, with a longhouse, palisade and watchtower.
• Yeti Dens.
• Ancient Ruins, with a sunken vault.
• Sacred Groves.
• Celestial, Void and Storm Sanctuaries, each home to its demi-god.

Every structure has its own loot chests. Each one is built a little differently and faces a random way.

Blocks:

• Ruin: Void Stone, Corrupted Bricks (with stairs and slab), Abyssal Crystal, Crimson Rune Block, Shadow Lantern.
• Ancient: Ancient Stone Bricks (with stairs and slab), Carved Runestone, Celestial Crystal, Celestial Lantern, Ancient Pillar, Rune-Engraved Tiles, Mossy Ancient Stone.
• Dragon: Dragonbone, Crystalline Dragonstone, Dragon Scale Block.
• Frozen: Frost Crystal, Frozen Stone, Ancient Ice Bricks, Yeti Fur Block and Rug.
• Sacred wood: log, planks, stairs, slab and leaves.
• Plants: Glowing Flower, Magical Foliage, Enchanted Roots.
• Vikling: Reinforced Timber, Carved Tribal Wood, Vikling Roof and slab, Fur Rug, Wooden Palisade.
• Six boss trophies, crafted from each boss's rarest drop.

Gear:

• Three new armour sets: Ruin, Dragonscale and Yeti Hide (Yeti Hide keeps out powder snow).
• New weapons: the Ruinblade, the Dragonbone Greatsword and the Chief's War Axe.
• Recipes for all of the new blocks, armour, weapons and trophies.

Everything looks better:

• All models rebuilt with far more detail, including the cultists, the Champion and the demi-gods. The Cultist Knight now wears white plate.
• Weapons and boss relics (hearts, cores, horns, fangs) are true 3D in your hand, and keep a crisp icon in your inventory.
• New custom particles: runes, embers, sparks, crystal shards, motes, feathers, snowflakes, leaves and smoke. Every creature and attack has its own.
• Animated, decorated boss bars for every boss and mini-boss:
  • The bar flows and the ornaments pulse.
  • Embers, snow, leaves or sparks drift up from it.
  • It flashes and shudders when the boss enters a new phase, and throbs when the boss is nearly dead.
• All glow effects and particles still work with shader packs. The particle setting and render distance are respected, so big fights stay smooth.

Spawning and commands:

• Wraiths, hounds, moths, deer, yetis, golems and dragonborn now spawn naturally in their biomes (they can be turned off in the server config).
• /xaelion structure <name> builds any structure where you stand (operators only).

Note for Flashback users: replays recorded on 1.2.0 or older won't play back on 2.0.0, because the new creatures change the game's internal creature numbers. Keep a copy of the old version if you need to watch old recordings.

1.2.0 (Seraveil 2.1.3 / Zephyra 1.0.3 / Xaelion 0.2.0)

New: the Demi-Gods. Three rare, powerful beings. They're mini-bosses with a boss bar and two phases, but well below Xaelion's true gods. None of them attacks you on sight.

• Celestial Demi-God: white-gold armour, a halo and wings, and a radiant lance. It is sworn against the cult of Noctyra: it attacks cultists on sight, and cultists attack it.
  • Abilities: lance thrusts, the Celestial Lance beam (its aim locks before it fires, so you can sidestep it), Heaven's Descent (it leaps into the sky and crashes onto a marked circle), Divine Chains (binds you in place), and Radiant Sanctuary (a healing circle for itself and its friends).
  • At half health it casts Solar Benediction, which empowers it and any nearby players it considers friends.
• Void Demi-God: violet robes, a fractured halo and orbiting void shards. It floats.
  • It is neutral until approached aggressively. Sprinting at it angers it at once. Standing close with a weapon out earns one warning, then its wrath.
  • Abilities: Entropic Touch (weakens, slows and starves), Void Fracture (three rifts that hurt and drag), Gravity Well (pulls everyone to a point, then implodes), Abyssal Blink (reappears behind you, often between attacks), and Event Horizon (a growing void sphere).
  • At half health it becomes Unbound: faster and more erratic.
• Storm Demi-God: blue-silver armour, lightning veins, a crown of bolts and a spear.
  • It is territorial. Linger near it and it warns you with thunder; stay and it attacks.
  • Abilities: Thunder Spear (a thrown bolt that calls lightning down), Tempest Dash, Stormcall (lightning strikes on marked spots), Static Prison (an electric cage you can't walk out of), and Eye of the Tempest (a storm wall that throws you back).
  • At half health it unleashes the tempest.
• Offerings: right-click a calm demi-god with the right gift for a blessing, once per day per demi-god. The Celestial takes a gold ingot (Regeneration, Absorption), the Void an amethyst shard (Night Vision, Slow Falling), and the Storm a copper ingot (Speed II, Haste II). A player the Storm has blessed today may stay on its ground in peace. Right-click empty-handed to hear what it has to say.
• Grudges fade: if you leave (or die), a demi-god calms down, slowly heals and returns home. Its spells only hit its enemies, never bystanders.
• Every big attack has a visible warning first. The effects use vanilla particles and lightning, so they work with shader packs.
• New items: Celestial Feather, Sunstone, Void Fragment, Fractured Halo Shard, Storm Shard, Tempest Core, and three weapons:
  • Radiant Lance: extra damage to cultists and undead.
  • Voidrend Blade: weakens and slows what it hits.
  • Stormcaller Spear: sometimes calls lightning on hit.
• Demi-gods don't spawn naturally yet. Their sanctuaries will come with the structures update. For now use the spawn eggs in the Xaelion tab, or /xaelion spawn celestial_demigod, void_demigod or storm_demigod.

Note for Flashback users: replays recorded on 1.1.0 won't play back on 1.2.0, because new creatures change the game's internal creature numbers.

1.1.0 (Seraveil 2.1.3 / Zephyra 1.0.3 / Xaelion 0.1.0)

New: Xaelion — Creatures of the Realm. The first creatures of Xaelion arrive: the cult of Noctyra.

• Dark Cultist: slashes with a ritual dagger, hurls dark bolts, and grows stronger when fighting beside other cultists. When no enemy is near, cultists gather and chant their rituals.
• Cultist Archer: keeps its distance and fires corrupted arrows that wither and weaken. It also looses a five-arrow Shadow Volley and leaps backward to fire when cornered.
• Cultist Mage: casts homing void orbs, heals wounded cultists, summons Shadow Wisps, lays Corruption Fields, and blinks away from melee.
• Cultist Knight: an armoured elite with a three-strike greatsword combo and a long Crushing Charge. Its shield turns frontal blows and answers them with a Retaliation Strike, and it protects nearby mages.
• Abyssal Cultist Champion (mini-boss): a mutated cult champion with a boss bar and a roaring entrance. It fights with a wide Abyssal Sweep, a ground slam and shadow tendrils that burst from under its enemies. It calls reinforcements as it weakens and enters a Dark Frenzy at low health.
• Every big attack has a visible warning and an opening afterwards. Cultists never hurt each other.
• New items: Dark Ritual Fragment, Abyssal Core, Cultist Cloth, Cultist Ritual Dagger, Abyssal Greatblade, and spawn eggs (new "Xaelion" creative tab).
• Cultists spawn rarely at night in dark forests, swamps and old-growth taiga. Spawning and difficulty can be changed in the server config.
• Commands for operators: /xaelion spawn <creature>, /xaelion warband, /xaelion champion, /xaelion clear.
• Glowing details use Minecraft's own glow rendering, so they work with shader packs.

Now requires GeckoLib (NeoForge 1.21.1).

Note for Flashback users: replays recorded on an older version won't play back on this one, because new creatures change the game's internal creature numbers. Keep the old version around if you need to watch old recordings.

1.0.2 (Seraveil 2.1.3 / Zephyra 1.0.3)

Flashback replay compatibility

• Fixed a crash/freeze ("Failed to load player") when watching a Flashback replay that included a player using Seraveil or Zephyra. Other mods sending packets to Flashback's replay-camera players could also trigger this — now handled safely.
• Fixed replays showing the recorded player as a plain vanilla avatar instead of their Seraveil/Zephyra transformation, even when they were clearly transformed during recording. Transformations, forms, and effects now display correctly when watching back a recording.
• Note: there can be a very brief (about one second) delay at the very start of playback before the transformed look appears, while the replay catches up to the recorded state. This is expected and not a bug — it only affects the first moment of playback.
• The in-mod HUD, screens, and cutscenes are now correctly hidden while watching a replay, since you're not actually playing during playback.

No new abilities or content in this release — this is a compatibility/bugfix update.

(Earlier versions were not tracked in a formal changelog.)
