Changelog — v0.5.0

Major Update
This update introduces new sigils, a mini-boss encounter, deep mechanical systems, and significant progression expansion.
Recommended for new and experienced players.


🔮 New Sigils & Magic Systems

Sigil of Time

A high-tier sigil focused on temporal manipulation.

  • Burst Form

    • Freezes time in an area around the caster

    • All affected entities are locked in place while the caster remains mobile

    • Visual and sound effects emphasize temporal rupture

  • Drain Form

    • Drains time from nearby entities

    • Enemies receive strong slowing, weakness, and mining fatigue

    • Caster gains speed and haste

  • Fracture Modifier

    • Temporal instability causes partial time reversal

    • Affected entities may move using inverted motion deltas

    • Creates unpredictable and dangerous outcomes


Sigil of Space

A powerful sigil that manipulates spatial forces and distortion.

  • Burst Form

    • Generates spatial fluctuations around the caster

    • Entities are violently pushed, scattered, or displaced

    • Highly chaotic and visually intense behavior

  • Drain Form

    • Applies spatial pressure to nearby entities

    • Inflicts disorientation, darkness, nausea, and slowing

    • Grants movement and mobility buffs to the caster

  • Fracture Modifier

    • Causes spatial collapse and scaling instability

    • Affected entities temporarily lose effective reach, speed, and attack control

    • Represents literal “breaking” of spatial rules


🩸 Abyssal Content

Abyssal Remnant

A new hostile mini-boss encountered under specific conditions.

  • Can manifest under unstable magical conditions

  • Exhibits aggressive and unpredictable behavior

  • Defeating it triggers a critical choice


Hearts of the Abyss

Two powerful items obtained from the Abyssal Remnant:

Enslaved Heart of the Abyss

  • Cannot be held normally

  • Actively moves within inventory slots

  • Periodically grants:

    • Mana Regeneration

    • Strength

    • Darkness

    • Nausea

  • Emits disturbing sounds

  • Occasionally causes hallucination-like effects

Purified Heart of the Abyss

  • Used in advanced crafting

  • Can cure severe magical corruption

  • Acts as a stabilizing catalyst for high-tier sigils


☣ Magical Instability & Magic Cancer

  • Casting powerful sigils increases Instability

  • At 100+ Instability, players risk developing Magic Cancer

  • Effects include:

    • Permanent mana cap loss

    • Severe long-term debuffs

  • Magic Cancer can only be cured by:

    • Death

    • Totem of Undying

    • Purified Heart of the Abyss (with heavy cost)


      ✨ Visual & Audio Improvements

      • New particle effects for Time and Space sigils

      • Ambient and impact sounds for:

        • Temporal freeze

        • Spatial rupture

        • Abyssal entities

      • Improved visual feedback for unstable magic


      🏆 New Advancements

        • Abyssal encounters

        • High instability casting

        • Soul fragmentation
