Harvest Siege

Harvest Siege is a NeoForge 1.21.1 survival-defense mod. Place the Harvesting Core in your base, insert a Harvest Catalyst, and face escalating nightly monster raids — then convert that danger into energy and resources.

How It Works

Place a Harvesting Core anywhere in your world.
Insert a Harvest Catalyst into the Core's GUI.
When night falls, the Core activates and hostile mobs raid your base, all targeting the Core.
Defend the Core to keep it alive and collect the rewards.

Tip: Place the Core near a bed and base utility blocks (chest, furnace, crafting table, etc.) to unlock a Base Bonus — increased max HP, better regeneration, and higher resource output.

The Harvesting Core

Stat	Value
Max HP (base)	1,000
Max HP (with Base Bonus)	1,250
HP regeneration	Passive — resumes after a brief damage cooldown
Automation	FE and inventory via NeoForge capabilities

The Core GUI displays everything at a glance: HP, catalyst slot, orb slot, output slot, survival day, mob level, stored FE, and current output rate.

Plays a hit sound and emits particles when struck by raiders.
Opening the GUI is safe — right-clicking with a block in hand opens the interface instead of placing the block.
Pushes third-party HUD overlays (e.g. Jade) downward to prevent overlap with the Core HP bar.

Nightly Raids

Raiders spawn about 64 blocks away and are built to reach your Core no matter what is in their way.

Block breaking — Raiders breach player-made walls. Break speed scales with block hardness, so tougher materials buy more time, but nothing stops them permanently.
Smart navigation — Raiders climb, step over ledges, and use natural slopes before resorting to digging.
Water traversal — Raiders swim and keep advancing instead of stalling in the sea.
Stuck detection — Raiders that make no progress are discarded and replaced by fresh attackers.
Retaliation — Raiders briefly fight back when hit, then refocus on the Core.
Scaling — Raider stats grow with your survival day count. Using /time set does not affect progression.

Raider Types

Raider	Trait
Standard Raiders	Pathing zombies, skeletons, and similar mobs
Engineer Zombie	Leather helmet, iron pickaxe; places dirt to bridge pits or scaffold upward
Bomber Zombie	TNT head, extremely fast, very fragile; blasts wall breaches or deals burst damage to the Core on contact
Jump Piglin	Zombified piglin that vaults over walls with a powerful leap on cooldown
Mother Spider	Visibly larger spider that releases a swarm of smaller Core-targeting spiders on death

Orb System

Insert an Orb alongside the Catalyst to generate resources during raids. All Orbs and Catalysts are non-stackable. Output scales with mob level.

Orb	Resource	Delivery
Electric Orb	FE (Forge Energy)	Pushed into adjacent cables and machines
Nature Orb	Nature Shards	Placed into the Core output slot
Mining Orb	Earth Shards	Placed into the Core output slot

The GUI shows the current generation rate (FE/t or items/s) in real time.

Shard System

Shards are crafted into bulk vanilla materials via shaped recipes. All conversions output ×16 compared to standard crafting.

Nature Shard → Crops & Growth Items

Seeds, crop items, fungi, canes, bamboo, berries, kelp, and all major sapling/propagule variants.

Earth Shard → Ore-Derived Materials

Coal, raw metal drops, redstone, lapis lazuli, quartz, emerald, diamond, gold nuggets, and other mid-to-late progression minerals.
