To reach the end game content in Runes of Magic and progress through the quest zones efficiently, here's a step-by-step guide:

Starting Zone: Begin by creating a character and completing the starting zone quests. These quests introduce you to the game mechanics and provide basic gear and experience.

Varanas City: Once you finish the starting zone, you'll be directed to Varanas City. Here, you'll find several quest hubs that act as gateways to different zones. Speak with NPCs marked with exclamation marks (!) above their heads to receive quests.

Quest Hub Progression: Follow the quest chains in Varanas City, completing all available quests before moving to the next quest hub. Each quest hub will direct you to a specific zone based on your level.

Zone Progression: As you complete quests in each zone, you'll unlock access to new zones with higher-level content. Be sure to fully explore each zone, as there may be hidden quests or side objectives that reward valuable items and experience.

Grouping: Some end game zones may require group play due to their difficulty or specific mechanics. Consider joining or creating a guild to find like-minded players for group content. You can also use the game's chat channels to find groups or ask for help.

Instance Dungeons: Runes of Magic features various instance dungeons that provide challenging content and valuable rewards. As you progress through the quest zones, keep an eye out for quests that unlock these dungeons. Completing them with a group can yield powerful equipment and additional experience.

Elite Skills: As you advance further into the game, you'll gain access to Elite Skills. These skills offer additional abilities and powers for your character. Pay attention to quests or trainers that unlock these skills, and make sure to train and utilize them effectively.

End Game Zones: After completing the main quest zones and reaching the maximum level, you'll enter the end game phase. At this point, focus on accessing and completing high-level raids, dungeons, and PvP content. These activities typically offer the best rewards and provide the most challenging gameplay.

Remember to regularly upgrade your gear, enhance your equipment with runes, and allocate your talent points wisely. Additionally, participating in events, joining a community, and staying updated on game forums or official announcements can enhance your end game experience.

Keep in mind that game updates and changes may occur, so it's always a good idea to consult the official Runes of Magic resources and community for the most up-to-date information and strategies.
