Crimson Storm Bolt

Edition: Java Edition · Minecraft Version: 1.21.5 · Mod Loader: Fabric

Quickstart

1. Craft the Supercell Storm Bolt (lightning rod + redstone blocks) — see recipe below.
2. Hold it and right-click to summon a randomized supercell. A bold chat message names the storm type and its starting coordinates.
3. The sky fills with a massive dark rotating cloud deck. After 2–4 minutes tornadoes may begin to touch down.
4. Craft a Radar block, place it, and right-click to open the dual-tab GUI — track storm intensity, tornado positions, and core location on a circular scope.
5. Right-click the Bolt again at any time to immediately dismiss the storm and despawn all tornadoes.
6. Operators can spawn any specific tornado with /Tornado emf1 through /Tornado emf5 (no argument = EMF5).

Overview

Crimson Storm Bolt is a full storm-chasing experience. One item — the Supercell Storm Bolt — conjures a randomized tornadic supercell that grows over time, darkens the entire sky, and steers toward players in a sweep-and-return pattern. Tornadoes lift mobs and blocks, scale in size with EF rating, and are visible from a great distance. A suite of craftable blocks lets you monitor, survive, and escape: the Radar opens a cinematic dual-tab GUI, the Tornado Siren automatically sounds when a funnel touches down, the Tornado Sensor outputs a redstone signal, the Forecast Station shows the next natural storm countdown, and the Weather Car gives you a deployable escape vehicle with a built-in minimap. Reinforced Stone, Reinforced Glass, and Reinforced Wood provide EF1–4-resistant building materials.

What It Adds

How To Use

Supercell Storm Bolt

• Hold the Bolt and right-click to start the supercell. A bold red chat message displays the storm type and approximate core coordinates.
• The sky shifts to thunderstorm weather and a dark, rotating cloud deck covers the entire sky.
• Right-click again to collapse the storm instantly.
• A 2-second cooldown prevents accidental double-triggers.

Tornado Command

Operators (permission level 2) can spawn tornadoes directly with /Tornado or /tornado:

The command triggers sirens, lightning, and synchronized visual effects and respects the server's active tornado cap. The EMF5 tornado is extremely large with a wide destruction radius.

Weather Commands

Operators (permission level 2):

Radar Block

1. Place the Radar and right-click to open the GUI.
2. Two tabs — RADAR and STORM INFORMATION — click to switch.
3. RADAR tab: Circular scope with real radar colors (green → yellow → orange → red → purple), tornado markers as colored triangles by EF rating, your player position dot, and a compass showing your facing direction at the time of opening. Scroll the mouse wheel to zoom in or out (0.5× to 4×).
4. STORM INFORMATION tab: Storm stage, EF ratings, sizes, threat levels, tornado distances, and the EF color key. Text is laid out to avoid overlap.

Tornado Triangle Colors on Radar

Storm Wind Gauge

Hold and right-click to take a reading:

• Wind line — speed in mph/knots and category (color-coded).
• Rain/Hail line — whether heavy rain or hail is present.
• Action bar — distance to the nearest tornado or storm core.

Wind Categories

Heavy rain flags above 45% storm intensity. Hail activates above 68% intensity within ~135–190 blocks of the core.

Forecast Station Block

Right-click to receive: current storm status, a detail line, and an action bar countdown to the next natural 30-minute cycle.

Tornado Siren Block

Place anywhere. When any tornado touches down, all placed Tornado Sirens automatically activate — repeating horn and bell sounds audible from a long distance, plus particles, for 15 seconds. The block switches to a powered state while alarming.

Tornado Sensor Block

Polls for active tornadoes every 10 ticks. Outputs redstone strength 15 while at least one tornado is active; emits small red dust particles above it. Drops to 0 when all tornadoes dissipate.

Weather Car

1. Hold and right-click to deploy the vehicle ~2.4 blocks ahead. Consumed on placement in Survival.
2. Right-click the car to mount. Drive with W/A/S/D. Sprint to dismount.
3. While riding, a WEATHER CAR MINIMAP HUD appears in the top-right corner showing a ~420-block radar map with grid, range rings, compass, a YOU marker, a CORE cross, and colored EF triangle markers for every active tornado.
4. Live X/Y/Z coordinates, active tornado count, and map range are shown in the HUD footer.
5. The car has 28 HP and can be destroyed. The minimap disappears when you exit.

Abilities And Mechanics

Natural Storm Spawning

• One natural storm may spawn every 30 real-world minutes. The first cannot occur until at least 30 minutes after world creation.
• If a custom supercell is already active, the natural cycle is consumed and no second storm spawns.
• A random non-spectator Overworld player is chosen; the core spawns within ~96 blocks of that player.
• All players receive a bold dark-red announcement of the storm type and coordinates.

The Supercell

Every storm is fully randomized at spawn:

• Intensity ramps from ~12–28% up to 92–100% over several minutes.
• Movement: sweeps past you ~28 blocks to one side, then loops back through your position at half speed. The storm moves at 2× reduced pace overall.
• Tornado delay: tornadoes cannot form until 2–4 minutes after spawn and intensity ≥ 58%.
• Duration: 15 minutes, then the storm dissipates automatically.

Storm Variants

At 90%+ intensity the label gains a MASSIVE prefix.

Cloud Deck

A solid geometry-based (non-particle) cloud deck covers the entire sky, rotating with the storm core — no particle lag. Color darkens with intensity: dark gray → very dark gray (55%+) → near-black (75%+). The storm's visual footprint starts small and expands with reflectivity. Above tornado positions, clouds dip lower and rotate faster, forming a visible wall-cloud shape that marks where tornadoes will emerge.

Tornadoes

• Spawn under the storm's hook-echo position once the delay and intensity thresholds are met.
• Stay attached to the storm — they move with the storm's drift and are pulled back toward the core if they stray too far. Multiple tornadoes are kept visibly separated by a mutual repulsion system.
• Begin at EF1 and grow toward their randomized target EF rating over their lifetime.
• Visible from a great distance — funnel and particle scale increase with each EF level.

EF Scale Effects

• Entity pull: Living entities are drawn inward with swirling lift. Entities near the center take damage once per second, scaling with EF rating and intensity.
• Block pickup: Based on hardness vs. EF level — soft blocks (dirt, wood) at EF1; moderate blocks at EF2–3; stone-class at EF4; obsidian-class only at EF5. Blocks with block entities and fluid blocks are never picked up.
• Particles: Black dust-style particles scale in count and spread with EF rating.

Heavy Rain and Hail

Above 35% intensity precipitation increases around nearby players. Above 68% intensity hail spawns — exposed entities can take light freezing damage (1 heart normally, 2 hearts at 88%+).

Reinforced Blocks

All three reinforced block types resist EF1–4 tornadoes completely; only an EF5 can lift them. They drop themselves when broken.

• Reinforced Stone — mined with a pickaxe.
• Reinforced Glass — non-opaque; use for storm-proof windows. Mined with a pickaxe.
• Reinforced Wood — wood sounds, mined with an axe; natural-looking structural walls.

Progression And Strategy

1. Storms spawn naturally every 30 minutes. Have defenses ready before the first one arrives.
2. Craft early essentials first. Build the Storm Wind Gauge for real-time readings, a Forecast Station for the next-storm countdown, and Reinforced Stone/Glass/Wood to harden your base against EF1–4.
3. Understand the movement pattern. The storm sweeps past, then loops back. Moving away triggers re-acquisition. Plan your escape route before the storm peaks.
4. Note the announced variant. Lightning = no tornadoes but constant strikes. One-Tornado = one funnel. Tornadic = up to four funnels.
5. Use the ramp-up window. The storm starts weak. Place a Radar, Tornado Sirens, and a Tornado Sensor in the first few minutes before tornadoes can form.
6. Watch the Radar. Switch to the STORM INFORMATION tab for stage labels. When the storm reads tornadic or high threat — take shelter.
7. Deploy the Weather Car before the storm peaks. The built-in minimap shows tornado markers and the storm core in real time.
8. Use the Tornado Sensor with redstone to automate shelter doors, lights, or alarms the moment a funnel touches down.
9. Right-click the Bolt to end the storm at any time. All tornadoes despawn immediately.

Tip: EF5 tornadoes are enormous — their funnel and destruction radius are much larger than any lower tier and visible from a great distance. Only Reinforced blocks resist EF1–4; nothing but distance saves you from an EF5.

Tip: The Storm Wind Gauge tells you whether hail is currently falling — players within ~135–190 blocks of the core can take freezing damage at high intensity. Watch for the hail warning.
