"""External Bot Agent with deliberate decision-making logic:
- Evaluates targets via Radar sensor.
- Intelligently navigates around impassable obstacles (mountains and forests).
- Decides whether to negotiate party formation or refuse & fight based on strength.
- Explicitly engages in 3-bout D20 battles when adjacent to an opposing party/refusing bot.
- Parses battle results, bout rolls, scores, and absorbed members.
