Review Illagers & the Crimson Altar

Illagers & the Crimson Altar — README

Version: Reign of Nether v1.2.1a · Minecraft Java: 1.20.1

Read Me First (Must-Read)

• This map is heavily driven by datapacks. Late-game unit counts can be high and performance-heavy. Lower your graphics settings if needed for smooth play.
• Before each new run, execute /reload and /rts-hard-reset a few times to refresh datapacks and the world. (Or simply re-extract a fresh copy of the world.)
• If Heroes cannot be constructed, delete:
  ./<your world>/data/saved-herounit-data.dat and reload.

Overview

Illagers & the Crimson Altar is a rougelike tower defense RoN map built with datapacks. Each wave you’ll pick one sacrifice bonus at the altar, manage Anger to influence Special Waves, and survive as Negative Collectibles introduce global debuffs as the run progresses.

• Spawn: blue pad at map center (150, 60, 150).
• Do NOT place your TC (Town Center) anywhere else. Seriously—don’t.

Recommended Game Settings

• Population Cap: 300
• Beacon Victory Timer: 20 min
• Heroes: Enabled
• Difficulty: 9 min / wave or 6 min / wave (hard but rewarding once you learn the map)

Core Mechanics

1) Sacrifices & the Altar

• At the start of every wave (including Wave 0), three sacrifices spawn on the altar near spawn. Their effects are shown in chat.
• Claim an effect by killing the matching Villager.
• A fourth slot usually spawns a special llama. Killing it refreshes the sacrifice set but increases His Anger by +1.

2) Anger (Bossbar)

• Visible at the top as a bossbar; starts at 4.
• Each +1 Anger = +10% chance the next wave becomes a Special Wave.
• Anger changes via interactions (e.g., different llamas, certain bonuses). Wave 5 also adds +2 Anger naturally.
• At 10 Anger (max), something special happens.

3) Special Waves

• Based on Anger, a Special Wave may replace a normal wave; enemies receive special bonuses (announced center-screen).
• Special Waves grant one extra upgrade choice: after you take your normal sacrifice, an additional option appears on the altar.
• In this extra choice, the usual refresh-llama is replaced; killing it reduces Anger by 2. Proceed carefully.

4) Negative Collectibles

• At Wave 0, the run rolls 2 Negative Collectibles from a pool for this run.
• They activate at Wave 3 and Wave 8 respectively.
• Displayed on the action bar; once active, their text turns red.

Pool (internal key → effect)

• "bony": Friendly units −30% Max HP.
• "air_strike": Each wave, two waves of lightning-charged Creepers drop randomly within 80 blocks of map center.
• "weakness": Friendly melee units −60% damage.
• "water_pollution": Friendly units permanently Slime-infected.
• "open_wound": The first time a friendly unit is hit → Wither III for 20s.
• "fatty": Enemy units +50% Max HP.
• "keratosis": Enemy units +8 Armor.

Troubleshooting

• UI/logic seems off or bonuses don’t appear → Run /reload and /rts-hard-reset before starting a new run.
• Heroes can’t be built → Delete ./<world>/data/saved-herounit-data.dat, then reload.
• Performance drops → Lower graphics settings (render distance, particles, clouds), reduce shaders, and avoid running other heavy datapacks concurrently.

Tips

• Manage Anger: refreshing sacrifices via llama is powerful but pushes you toward Special Waves. Use Special Waves’ extra choice to lower Anger when needed.
• Plan for Wave 3 / 8 when Negative Collectibles activate.
• Some Special Waves can be opportunity waves if you’re prepared; others are better avoided by keeping Anger in check.
