What's new

New Content

Spells

  • Added "Totem of Permafrost": A more Minecraft-like alternative to an ice breath spell.
  • Added "Field Overseer": A turret device focused on quality over quantity.
  • Added "Servant Gaze": A costly servant, but one worth the investment.
  • Added "Fujin": Wield countless blades like a breath attack.
  • Added "Terra Resonance": Amethyst has become a common companion to modern magic, so now you can find it.
  • Added "Wizardlamp": A lantern that floats like an angel.
  • Added "Otherworld Lens": Honestly, what it does is basically cheating.

Items

  • Added "Shard of Spell Extraction": A consumable that helps make use of items found in the Catacombs.
  • Added "Catalystbook of Chargecast": If casting can be skipped, then surely the opposite should also be possible.
  • Added "Greatshield of Spellcaster-Bulwark": Designed for heavy defensive builds.
  • Added "Parrycast Buckler": Extracts the parry-focused gameplay from a previously added shield.
  • Added "Ring of Weapon Attackcast": A ring-based version of the Swingcast Staff.
  • Added "Luminous Device": Keeps the area around you illuminated; essentially a torch holder.

Changes / Tweaks

In preparation for the 1.0 release, older content continues to receive extensive reviews and major balance adjustments.

Spell Balance Adjustments

  • General
    • Offensive spells can no longer damage other players while PvP is disabled, the caster's own pets, the caster's own summoned entities, and similar allies.
  • Higanbana
    • Changed so it attacks a fixed number of times from a single cast instead of attacking once per recast.
    • Changed so it remains at the location where it was cast instead of following the caster afterward.
    • Changed so it appears slightly in front of the caster when activated.
    • Changed so the number of attacks is fixed and no longer scales with spell power.
  • Thermal Process
    • Reduced mana cost. (Lv1: 30/s -> 20/s)
    • Increased damage.
    • Adjusted the number of items processed.
    • Changed so range is fixed and no longer scales with spell power.
  • Shock
    • Reduced cooldown. (1.5s -> 1s)
    • Changed so range is fixed and no longer scales with spell level.
  • Arcane Beam

    • Reduced cooldown. (20s -> 12s)
    • Increased damage.
    • Reduced cast time. (5s -> 3s)
    • Adjusted the damage scaling because it was using an unintended formula and had become too strong.
  • Assist Wings
    • Changed so the number of additional jumps is determined only by spell level and no longer scales with spell power.
    • Changed its behavior while holding a Mace or Smashcast Scepter.
    • This also fixes an issue where the number of available jumps would not reset after landing.
    • Changed Slow Falling from a potion effect to a custom implementation.
    • Changed jumping movement speed so it now takes the player's existing movement speed into account.
  • Auto Magnet
    • Changed so collection range is determined only by spell level and no longer scales with spell power.
    • When mana consumption on collection is enabled, the mana cost is now fixed and no longer scales with spell power.
  • Auto Turret

    • Increased mana cost. (Lv1: 70 -> 80)
    • Changed so the crossbow's health scales only with spell level and no longer scales with spell power.

    • Reduced how strongly the crossbow's arrow count scales with spell power.
  • Inscribe Ice
    • Reduced mana cost. (Lv1: 50 -> 30)
    • Changed the dagger thrown directly forward so it travels straight without random spread.
  • Frost Rune
    • Removed self-damage.

  • Magic Spear
    • Reduced mana cost. (Lv1: 100 -> 30)

    • Removed self-damage.
  • Fly Swatter
    • Removed self-damage.
  • Mana Slash
    • Reduced damage.
  • Mirage Avoidance
    • Extended invulnerability so it remains active throughout the movement instead of ending partway through.
  • Heavenly Fist
    • Increased mana cost. (Lv1: 60 -> 80, Lv3: 80 -> 120)
  • Moon Light
    • Increased range.
    • Added an effect that recreates a counter-spell interaction when an attack hits.
  • Breaching Enemy
    • Changed so the number of projectiles is fixed and no longer scales with spell power.

    • Set the maximum range gained from spell power to 32 blocks.
    • This limit can be changed through server configuration.

Item Balance Adjustments

  • Unified enchantment compatibility between the 1.20.1 and 1.21.1 versions.
    • Smashcast Scepter remains an exception because it uses Mace enchantments.
  • Significantly reworked the Spellgun system.
    • Spellguns are now used with left-click while held in the main hand.
    • This means Spellguns can no longer be used for melee attacks, but offhand items can now be used normally.
    • When held in the offhand, Spellguns are still used with right-click.
    • Removed spell power bonuses from all Spellguns.
    • Reworked the intended role and performance of each Spellgun.
    • Each material now has a more clearly defined role.
    • Crafting recipes have also been broadly adjusted alongside these changes.
    • Added a calibration option where inserting a Silver Spell Amplifier into the adjustment slot through the Spell Calibration Bench allows enchantment and upgrade effects to apply while the Spellgun is held in the offhand.
    • Cooldown reduction now affects Spellguns.
  • Reduced the bonus from the Attunement enchantment to 3% per level.
  • Reduced the bonus from the Tense enchantment to 4% per level.
  • Adjusted the behavior of the Transcendence enchantment.
    • Standardized its activation conditions, which previously varied between items.
    • Handheld items now function in either the main hand or offhand.
    • Equippable items now function only while equipped.
    • When multiple items affect the same spell, only the highest enchantment level now applies.
    • Adding all enchantment levels together and increasing every spell was unintended behavior.
    • Elemental Bow remains an exception, and its selected spell level continues to be increased directly.
  • Changed Amulet of Satellite Followcast configuration so it is now handled through the Spell Calibration Bench.
    • A Silver Ring is now required to use spells with cast times.
  • Significantly reworked Reflectcast Shield.
    • Slightly increased its recipe difficulty.
    • Changed its available enchantments.
    • Like a vanilla shield, it can no longer block immediately after being raised.
    • Imbued spells can no longer be selected.
    • Changed so successfully blocking is enough to trigger the spell.
    • Spell activation now consumes mana.
    • Spells with cast times require a Silver Ring in the adjustment slot.
    • While a Silver Ring is installed, continuously cast spells can now be used.
    • After a successful block, the spell continues until blocking is released or mana runs out.
    • While a Shard of Wisdom is installed, the shield attempts to cast the currently selected spell instead of the imbued spell.
  • Simplified the behavior of Scrollcaster Gauntlet when Mithril Freecast Staff is placed in its adjustment slot, as the previous behavior did not match its description.
    • A Silver Ring is no longer required.
  • Replaced Mage Light with Terra Resonance among the spells contained in Explorer's Codex.
  • Added Companion Trunk to the spells usable through Storage Stabilizer.
  • Improved Storage Stabilizer so its currently selected spell is easier to identify.
  • Reduced the recipe difficulty of Ring of Spell Cast Parrying.
  • Changed the Swingcast Staff series so it accepts more magic-related enchantments.
  • Changed Spell-Sided Edge so it accepts more magic-related enchantments.
  • Changed Iron Swingcast Staff and Copper Swingcast Staff so they no longer accept spells that require recasting.
  • Slightly increased the school-specific spell power bonus of Copper Swingcast Staff.
  • Removed the school-specific spell power bonus from Gold Swingcast Staff.
  • Changed Enchantress's Robe so it no longer accepts the Transcendence enchantment.
  • Changed the Stealth Runic armor series so it accepts more magic-related enchantments.
  • Imbued spells can now be extracted from:
    • Enchantress's Robe
    • Stealth Runic Talisman
    • Chromatic Magia Dress Coat
    • Mana Force Blade
  • Reduced the cooldown reduction of Craftsman's Delight. (66% -> 50%)
    • This value has been moved to server configuration together with the effect of Magi-Agent's Boots, so it can be restored if desired.
  • Increased the enchantability of Enchanted Circlet from the minimum value to approximately the same level as Netherite tools.

Other

  • Updated the Simplified Chinese translation.
    • Thanks: LongFei32
  • Added item icon changes to Storage Stabilizer based on the currently selected spell.
  • Added visual feedback to indicate when Personal Shelf is being cast in export mode.
  • Changed Scrollcaster Gauntlet and Storage Stabilizer so spell selection changes are reflected immediately.
  • Spell-Stained Arcane Ingot can now be used as a metal material in Iron's Gems 'n Jewelry. (1.21.1 only)
  • When Mana Force Blade has Sharpness, its displayed damage now includes the Sharpness bonus. (1.21.1 only)
    • In 1.21.1, Sharpness normally does not affect the damage shown in the tooltip. However, because the Sharpness bonus also affects the mana-consumption penalty of Mana Force Blade, it is displayed here for clarity and consistency.

Bug Fixes

  • Fixed an issue where Auto Turret did not visually face the correct direction.
  • Fixed an incorrect impact effect for Shock.
  • Fixed an issue where Lethal Assault could not be activated through charging with Focus Staffbow.
  • Fixed an issue where Focus Staffbow charge did not affect the damage of certain spells.
  • Fixed an issue where some spell projectiles would occasionally curve in unintended directions.
  • Fixed and added safeguards for rare issues where certain items or spells could stop functioning or fail to end properly.
  • Fixed an issue where projectile entities that gain no meaningful effect from being on fire could still catch fire.
  • Fixed an issue where certain spell items still applied cooldowns in Creative Mode even when Creative cooldowns were disabled.
    • Amulet of Spell Autocast remains an exception because disabling its cooldown would cause it to activate continuously, so it always applies a cooldown regardless of this setting.
  • Fixed an issue where the selection UI overlapped when different items that display a selection UI while sneaking were held at the same time.
    • As with identical items, the main-hand item now takes priority.
  • Fixed an incorrect holding pose when Storage Stabilizer was held in the offhand.
  • Fixed incorrect held-item bonus settings for Diamond Spell Amplifier and Netherite Spell Amplifier.
  • Changed the arrow consumption behavior of Elemental Bow when casting spells so it now uses the same system as Focus Staffbow.
  • Fixed an issue where Sense Evil detection did not render through walls when Oculus or Iris was installed.
  • Fixed an issue where the full Magi-Agent Suit set accepted Tense and Alacrity. (1.21.1 only)
  • Fixed an issue where Focus Staffbow accepted sword-related enchantments. (1.21.1 only)
  • Fixed an issue where Surge and Attunement on Mana Force Blade did not function. (1.21.1 only)
