⚠️ PRAXIC is in early development. Detection accuracy is improving with each release but false positives may occur. Not recommended for large production servers until a stable release. Use at your own discretion.

| Movement | Combat | World | Client | ||||

🔮 Smart Engine
🧠 Physics Prediction — Simulates vanilla gravity tick by tick. Compares predicted position to actual. Catches fly and hover that threshold checks miss.
🌐 Lag Compensation — Thresholds scale with each player's latency. No configuration needed.
🔄 Violation Decay — VL decreases over time without new flags. Clean players recover on their own.
↩️ Setback — Silent teleport to last safe position instead of disconnect.
⚙️ Actions
Every check carries its own configurable response:
| Action | Behavior | |
|---|---|---|
| ⚠️ | Warn | Alert the player, log the violation |
| 🚪 | Kick | Immediate disconnect |
| 🔨 | Ban | Permanent, automatic |
| ↩️ | Setback | Silent teleport to last safe position |
🔔 Integrations

💬 Discord Webhook — Rich embeds with full details. One line in config.
🔗 Event API — PraxicViolationEvent for custom mod integrations.
🔥 REVEX — Escalation Addon
Graduated punishment system built on top of PRAXIC. Warn → 15 min → 1 hour → 1 day → permanent. Fully automatic.
