EndSustain 0.2.0 Changelog

New Boss Skills

• Added Touhou Danmaku Barrage:
  • Uses the native danmaku system from Touhou Little Maid;
  • Fires four large purple projectiles toward the target player per cast;
  • Each projectile deals 1,000 damage;
  • Projectiles spread in a narrow fan pattern.
• Added Glacier Strike:
  • Uses the native glacier projectile from PeyroScythe;
  • Summons a large glacier above the target and drives it downward;
  • Preserves the original impact damage, falling ice, area damage, and ice-quake visuals.
• Added Earthquake:
  • Uses the native Earthquake AOE from Iron's Spellbooks;
  • Creates an 8-block-radius earthquake at the target position;
  • Includes area damage, slowing, ground particles, sound effects, and camera shake.
• Danmaku Barrage, Glacier Strike, and Earthquake are now part of the Boss's normal ranged skill pool.

Charm Finisher

• Charm and the finisher are now explicitly treated as one complete skill instead of two independently scheduled abilities.
• The Boss must continuously track the same player for 12,000 ticks—10 minutes—before casting the Charm finisher.
• The timer resets if the player leaves the targeting range, dies, changes dimension, or the Boss changes targets.
• The timer restarts only after the full Charm, time-stop piercing, and sheathing sequence is complete.
• The piercing phase retains its client-side screen-tearing overlay without forcibly changing the player's camera direction.

Post-Death Final Execution

• The final execution no longer activates early at low health. It now begins after the Boss receives combat-fatal damage.
• After death, the Boss remains present at zero health.
• Damage, healing, health changes, and repeated death transactions are blocked during this state.
• After a 30-tick delay, the Boss summons a Star Arrow formation:
  • Eight directions;
  • Five arrows per direction;
  • Forty Star Arrows in total;
  • A 20-block-radius Boss-centered domain;
  • A horizontal 6-block instant-kill domain around each arrow.
• A Star Arrow's instant-kill domain only activates after the arrow descends to battlefield height and approaches the player, preventing immediate kills while the arrows are still high in the air.
• The Star Arrow phase lasts 200 ticks—10 seconds. The Boss disappears and grants rewards only after this phase ends.

EndSustain Blade

• Increased the forced return time for player-thrown EndSustain Blades from 10 seconds to 30 seconds.
• Combat-fatal Blade attacks against the Boss now enter the Boss-specific final execution instead of being removed early by the generic death transaction.
• Fixed the Boss repeatedly casting its finisher after being reduced to extremely low health by the Blade.
• Improved the reliability of returning the thrown Blade to the player's inventory.

Boss Combat and Phase Fixes

• The Small Zhanjiang companion no longer triggers passive targeting, skill targeting, or Charm tracking.
• Added real-time targeting-range validation to normal teleportation. Teleports are rejected when the target is too far away.
• Added a complete phase-transition invulnerability lock:
  • Rejects all damage events;
  • Rejects external health changes;
  • Rejects healing and death calls;
  • Unlocks only after the dimension transfer completes.
• Fixed stale QunU UUIDs causing invalid sleeping-phase protection.
• Sleeping protection now updates when a QunU dies or is removed by any source.
• Added a 10-tick rate limit for entity-sourced non-player damage and a 5-tick limit for environmental damage. Player damage remains immediate.
• Added persistent encounter and phase data to reduce duplicate Bosses, duplicate portals, and phase rollback after dimension transfers.

Reward Fixes

• Boss-exclusive rewards are now granted only once.
• Every death-drop event removes exclusive ground drops before checking whether the inventory reward transaction has already completed.
• Fixed rewards appearing both in the player's inventory and on the ground.
• Rewards are inserted into the player's inventory first, and inventory changes are synchronized immediately.
• Fixed repeated death events duplicating the EndSustain Core, Halo, and enchanted books.

Other Changes

• Removed the old test command and test projectile path that fired Star Arrows directly toward players.
• Preserved the official eight-direction vertical Star Arrow formation used by the final execution.
• Updated the mod version to 0.2.0.
