Después de un poco de craneo, algo de codigo y un resto de testeo, implementé las reglas de los Youngs en Felucca:

• Los youngs no pueden ser atacados por jugadores viejos y vice versa.
• Los youngs no pueden ser atacados por monstruos a menos que ellos inicien el combate.
• Los youngs no pueden realizar actos beneficos sobre jugadores viejos.
• Los jugadores viejos si pueden realizar actos beneficos sobre los youngs.
• Los youngs si pueden realizar actos beneficos entre si, pero no atacarse.

Mas algunas reglas especiales del server:

• Los youngs y pks pueden viajar usando Recall, Sacred Journey y Moongates hacia cualquier destino (viajar a Felucca no impone ninguna limitación).

Por si a alguien le interesa implementar este sistema, el codigo es el siguiente: Reemplazar los dos metodos (beneficial y harmful) en Notoriety.cs, el codigo relevante esta en rojo (para modificar Recall, Sacred Journey y Moongates solo basta comentar las lineas correspondientes -las que tienen el texto ‘you cannot travel, etc’ en los codigos de cada hechizo). El codigo siguiente es válido para cualquier mapa con reglas de Felucca:
