Calamity Meter Mod
This mod brings two combat meters inspired by Terraria's Calamity Mod into Minecraft. Each meter has a unique charging mechanism and rewards skilled play with multiplicative damage buffs.
🔥 Rage Meter
The Rage Meter fills when you stay close to enemies. Get aggressive and push into danger to build up your fury.
Charging
- The meter ranges from 0 to 100.
- Charge rate depends on distance to the nearest enemy:
- When within 10 blocks of an enemy.
- During boss fights, the charge rate is tripled.
Draining
- The meter starts draining when you are out of combat (no enemies within range).
- Drain rate: 3.33% per second – a full meter empties in 30 seconds.
Rage Mode (Activation Key: G – customizable)
- When the meter is full, press
Gto activate Rage Mode. - Grants a +35% multiplicative damage bonus (applied after all other damage calculations).
- The bonus is multiplicative, not additive – meaning it scales with your existing gear for massive damage output.
⚡ Adrenaline Meter
The Adrenaline Meter is a high-risk, high-reward system designed for boss encounters. Stay untouched, build power, and unleash devastating damage.
Charging
- The meter ranges from 0 to 10000.
- Charges **only when within *_75 blocks_* of a boss**.
- Charge rate: 1000/3 per second – a full charge takes 30 seconds of uninterrupted survival.
- As long as you avoid damage, the meter steadily fills.
Losing Adrenaline
- Taking damage resets the meter to 0 and pauses charging for 1 second.
- When the meter is full, any hit will completely empty it – no partial loss, full reset.
- The amount lost scales with damage taken:
- lose everything.
Adrenaline Mode (Activation Key: H – customizable)
- When the meter is full, press
Hto activate Adrenaline Mode. - Grants a +150% multiplicative damage bonus – this is multiplicative and applied after all other damage bonuses.
- Use it wisely – once activated, the bonus lasts until you take damage or the effect expires.
🎨 Visual & UI
- Both meters appear as stylish bars near your hotbar.
- Rage Meter (red/orange theme) – located on the left.
- Adrenaline Meter (blue/cyan theme) – located on the right of the Rage Meter.
- Each meter features charging animations and particle effects that intensify as the meter fills.
- When a mode is activated, unique particle bursts surround your character.
