Final Fantasy 15 boasts an array of powerful weapons that become more and more necessary as you hunt down hulking daemons across the vast lands of Eos. While some can be modded to craft stronger versions of basic weaponry, the game's playable protagonist Noctis gains access to a number of historic blades thanks to his noble lineage.
As you scour the regions of Leide, Duscae and more, you'll come across a total of thirteen of these storied weapons – known officially as Royal Arms – hidden away deep inside Royal Tombs. As a bonus, players who claim every Royal Arm also unlock the "Faithful Heir" achievement or trophy on Xbox One or PS4, respectively.
Wielding these Royal Arms in battle is something of a double-edged sword, as your Hit Points (HP) continuously drain while one is in use. On the plus side, they ignore enemy resistances, offer a passive stat boost when equipped and play into Noctis' special Armiger Arsenal ability, as well as giving you a strong collection of weapons without having to scour for rare upgrade materials.
For those in a bind, below are the locations of all the Royal Arms in Final Fantasy 15.
