Secret of the Ancient City: Echo Dimension

Things Added and Changed in 1.0.4:

New Biomes: Added Endless Dark Caves and Fatal Ocean, increasing the Echo Dimension biome count from six to eight.

Sculk World Generation: All Echo Dimension biomes now receive denser Deep Dark-style sculk coverage.

Echo Ore Generation: Echo Ore now generates across the entire dimension instead of depending on individual biome files. It appears as rare 1–2 block veins between Y=-60 and Y=-50.

New Echothyst Blocks: Added Dormant Echothyst, Budding Echothyst, and Mature Echothyst with crystal shard growth and drops.

New Mini Structures: Added Altar, Bastion, Crypt, Reliquary, Shrine, and Watchtower structures with unique loot chests.

New Sonar Items: Added Echo Sonar and Echo Sonar Mk II for detecting nearby mobs, caves, and sculk activity.

New Large Echo Staff: Added a larger drilling staff with wider range, longer reach, and hardness-based drilling distance.

Cow’s Bucket System: Added Cow’s Bucket, Cow’s Water Bucket, Cow’s Lava Bucket, and Cow’s Milk Bucket.

Custom Milk Changes: Cow’s Milk Bucket now remains a custom milk bucket instead of turning into a vanilla Milk Bucket.

Echo Sword Changes: Echo Sword now applies Blindness instead of Darkness.

Echo Hoe Changes: Crop growth now activates only with Sneak + Right Click, allowing normal hoe tilling to work correctly.

Echo Shovel Changes: Suspicious Sand and Suspicious Gravel can now be recovered, with archaeology loot and rare diamond rewards restored.

Protector Staff Changes: The staff can drill through all breakable blocks, while harder blocks reduce the total drilling distance. Bedrock and other unbreakable blocks remain protected.

Echoenergy Stone Changes: The stone no longer disappears after supplying energy to the Echo Altar.

Tooltip Changes: Tooltips were simplified by removing unnecessary technical, cooldown, durability, and legacy information.

Pet Warden Changes: Pet Warden now attacks mobs damaged by its owner, follows normally while leashed, and no longer despawns.

Echo Warden Monarch Changes: The boss now drops one Warden Heart with a 100% drop chance.

Arena Changes: The arena area is cleared before generation to prevent terrain and structure overlap.

Echo Water Changes: Poison now activates only after approximately eight seconds of continuous contact.

Echo Book Updates: Added new information for items, bosses, progression, Echothyst, Sonar, and a warning that Diamond-tier or stronger pickaxes are required for mod blocks.

Performance Improvements: Removed heavy legacy scans, reduced unnecessary entity checks, optimized mob cleanup, and split large world generation tasks across multiple ticks.

World Generation Stability: Fatal Ocean terrain cleanup, structure placement, teleport safety, and chunk processing were improved to reduce freezing and generation errors.

Important: New biomes, structures, Echothyst, sculk coverage, and Echo Ore only appear in newly generated or previously unexplored chunks.
