Final Fantasy 15 All Royal Arm Locations Guide
Search the indicated locations to find all 13 Royal Arms and get the “Faithful Heir” achievement. Each Royal Arm has unique attack patterns and stat boosts. They can be used in combat by Noctis. They are more powerful than normal weapons but using them depletes your own health. Even if you do not want to use these weapons, you should equip them for the stat boosts they provide. Additionally, the Royal Arms bypass all enemy resistances and always deal full damage (no enemies are resistant to them). You automatically get the first seven Royal Arms during the main quests.
The remaining six Royal Arms are from dungeons and Royal Tombs that you must find on your own. None of them are missable. There is free roam after completing the story that allows you to go back to any place in the game. The dungeons are fairly difficult — one of them is for Level 55+. You can attempt to do them before leaving for Chapter 9, but they will be very difficult. It is recommended to first complete the story to get stronger. Note: You can also switch to the Easy difficulty in the game options at any point in the game. You cannot die while playing on the Easy difficulty.
