Bots autonomously progress through the skill system with:
- Intelligent task selection based on current level and available resources
- Resource management (banking, inventory management, item acquisition)
- Optimal pathing with gate awareness and world navigation
- Magic teleportation with visual cast animations
- Activity-specific AI (combat targeting, resource respawn detection, etc.)
Bots intelligently:
- Detect closed gates, doors, and barriers within 10 tiles
- Open gates directionally (toward their destination)
- Automatically handle AL Kharid tolls, Karamja boats, and similar gated regions
- Adapt routes when paths are blocked
- Real-time skill level tracking across all 19 skills
- XP-based rankings with visual displays
- Player vs. bot competition leaderboards
- Historical progress tracking
