Final Fantasy XV Royal Arms Ability Effects and Usage Tips: Guide
In Final Fantasy XV, the Royal Arms are a unique set of weapons tied directly to the lore of the Lucian kings. These powerful arms, once wielded by past rulers, offer Noctis unparalleled strength at a cost. Each Royal Arm drains HP with every swing, making them both a blessing and a burden in combat. Mastering their use is essential for players seeking to maximize Noctis’s potential, especially in challenging post-game content and boss fights. This guide delves into the abilities, effects, and strategic usage of each Royal Arm to help you harness their power effectively.
Understanding Royal Arms Mechanics
Before exploring individual weapons, it’s crucial to understand how Royal Arms function. Unlike standard weapons, Royal Arms consume a percentage of Noctis’s HP with each attack. This makes them risky to use, especially when health is low. However, they ignore enemy defenses and often possess unique abilities, such as stat boosts or special attacks. Equipping multiple Royal Arms can further enhance Noctis’s stats, even if they aren’t actively used, making them valuable for build optimization.
There are 13 Royal Arms in the base game, with additional ones available in the Royal Edition and DLCs. Each weapon varies in type, ranging from swords and daggers to shields and poles, catering to different playstyles.
