Core Game Mechanics

Sacrifices & the Altar

Every wave (including wave 0), the Altar spawns 3 sacrifices.
Their effects appear in chat.
Kill the corresponding Villager to select.
The 4th slot spawns a special Llama for refreshing sacrifices (starts with 6 refreshes).
Refreshing increases Anger by 1.

Anger (Bossbar)

Shown permanently at the top of the screen.
Starts at 2.
Each +1 Anger = +10% Special Wave chance.
Wave 5 naturally adds +4 Anger.
At Anger = 10, a special event occurs.

Special Waves

Based on Anger, a normal wave can be replaced.
Enemies gain special bonuses (shown via titles).
Special Waves grant an additional sacrifice choice.
The refresh Llama becomes a special Llama that reduces Anger by 2 when killed.

Negative Collectibles

At wave 0, 2 are selected.
They activate at wave 3 and 8.
Names appear on actionbar and turn red when active.

Negative Collectible Pool

Fragility: Friendly max HP –30%
Weakness: Friendly melee damage –60%
Pollution: Permanent Slime infection
Bleeding: First hit applies Wither III (20s)
Fatty: Enemy max HP +50%
Keratosis: Enemies gain +8 Armor

> Slimes ignore Fatty. Air Strike and Crowded removed.

Llama Camps & Couriers

Llama Camps may appear across the map and can be captured by players or enemies.
Move units into the camp’s area to accumulate capture progress, shown in the sidebar.
At 1000 capture, the camp becomes yours. Enemy presence reduces your progress.

Capture Rewards — Llama Couriers

If you control at least 1 camp, each wave spawns a Llama Courier at your base.
The courier travels to one of the map’s four corners; reaching the destination grants rewards:

1 camp: 100f / 100w / 250o
2 camps: 200f / 200w / 500o
3 camps: 300f / 300w / 750o + Refresh 1 sacrifice
4 camps: 400f / 400w / 1000o + Refresh 1 sacrifice

Slabstone

Slabstone is the key to unlocking the map’s three endings.

Tier I Slabstone

All negative collectibles become cursed:

Fragility: -50% max HP to allies
Weakness: -90% melee damage to allies
Pollution: Allies are permanently slimed; -30% max HP
Bleeding: First hit inflicts 20s Wither IV
Fatty: Enemies gain +100% max HP
Keratosis: Enemies gain +12 armor, +6 toughness

Tier II Slabstone

Beacon victory disabled
A Boss spawns at your base
Defeating it unlocks the third ending

Tier III Slabstone

Unlocks the collectible Redemption:

Allies gain +20% HP
Each unused “Refresh Sacrifice” chance grants an extra +20% HP

Endings

Ending I — Beacon Victory

Win normally by surviving until beacon completion.

Ending II — The Path of Wrath

When anger reaches maximum:

A special llama appears in the extra reward pool
Kill it to trigger Ending II
After beacon victory, an extra special wave starts
Defeat it to earn the second ending

Ending III — Redemption’s End

Triggered by Tier II Slabstone:

Fight and defeat the special Boss
Achieve the true final victory

Troubleshooting

UI or logic malfunction / upgrades not triggering → Run /reload and /rts-hard-reset several times before starting a new game.
Heroes cannot be constructed → Delete ./<world>/data/saved-herounit-data.dat and reload the world.
Performance issues → Lower render distance, particles, clouds, shaders; avoid running alongside other heavy datapacks.

Tips

Manage Anger wisely: refreshing sacrifices with llamas is strong, but increases the chance of Special Waves. Use special-wave bonus choices to reduce Anger when needed.
Plan around Round 3 and Round 8 — when Negative Collectibles activate.
Utilize Llama Camps and Llama Messenger bonuses for huge economic boosts.
Slabstone offers powerful benefits but comes with major risks — choose activation timing carefully.
