Using Royal Arms in Final Fantasy XV offers powerful combat advantages, but it also comes with a unique downside—self-damage. The game doesn’t explain this mechanic well, leading to confusion and misinformation among players. In this guide, we’ll break down how self-damage works and, more importantly, how to minimize and manage it effectively, allowing you to wield these weapons without constantly draining your health.

Understanding Royal Arms’ Self-Damage Mechanic

Before diving into mitigation strategies, it’s crucial to understand how self-damage functions.

1. Self-Damage Is Percentage-Based

Unlike typical weapons, Royal Arms inflict self-damage based on a percentage of your true maximum HP (not your current HP). This means stacking HP does not reduce the amount of health lost.

2. Self-Damage Only Occurs on Successful Hits

You don’t lose HP from swinging at the air—damage is only taken when you land a hit on an enemy. Additionally, whether you hit one or five enemies in a single swing, the health loss remains the same.

3. Different Royal Arms Have Different Self-Damage Values

Some Royal Arms deplete health faster than others, and certain attack types—especially Warp Strikes—cause significantly higher self-damage.

Avoiding Excessive Self-Damage

1. Be Cautious with Warp Strikes

Warp Striking with a Royal Arm is extremely risky unless you know exactly what you’re doing. The self-damage from Warp Strikes is disproportionately high, making it easy to drain your HP rapidly. Until you’ve mastered a weapon’s strengths and weaknesses, it’s best to avoid using Warp Strikes with Royal Arms. Instead, keep a non-Royal Arm weapon equipped for Warp Strikes.

2. Avoid Using Royal Arms for Crowd Control

Swinging Royal Arms into a large group of enemies or Warp Striking into a crowd is a quick way to lose massive amounts of health. This is comparable to stealing a cup of noodles from Gladio—a bad idea! Instead, focus on targeting a single enemy at a time to limit self-damage.

Countering the Health Drain

1. Take Advantage of Natural Health Regeneration

Just like self-damage, health regeneration in FFXV is percentage-based, meaning stacking HP is not an effective strategy. Instead, you should boost HP regeneration:

• Equip the Megaphone for Gladio: This allows him to passively increase your health regen during battle.
• Eat food that grants health regen bonuses: One of the best meals is the 100% crit rate food, which also enhances HP recovery.
• Use accessories like the Black Choker: While not always necessary, these can further increase your regeneration rate.

If you have already completed the game, you can use Chapter Select to reset Chapter 15, allowing you to farm multiple Megaphones for Gladio. Stacking three of them results in insane HP regeneration, effectively nullifying the self-damage effect.

2. Make Use of Tactical Pauses

Since Noctis regenerates HP over time, you can use techniques or defensive actions to buy time for healing:

• Ally Techniques: These make Noctis invulnerable for their duration, giving him time to regenerate HP without taking further damage.
• Blindsiding for Link Strikes: Taking advantage of Link Strikes allows you to attack safely while waiting for your HP to recover.
• Warping to Higher Ground: If you need a quick break, warp away to replenish both HP and MP.

3. Utilize Defensive Strategies

If you want to maximize passive healing, try these options:

• Take cover behind objects for fast HP recovery.
• Equip the Shield of the Just, which offers additional healing effects.
• Unlock the Regeneration Ability from the Ascension Grid—it’s cheap (only 99 AP) and highly effective.
• Equip Ignis with the Good Chamberlain accessory to make him use potions automatically if you dislike manual healing.

Building an Effective Royal Arms Loadout

If you’re focusing on Royal Arms, your build should prioritize HP regeneration over raw HP stacking. Here are some key takeaways:

• HP boosts are mostly irrelevant due to percentage-based self-damage.
• Regeneration accessories and buffs are your best friends.
• Switch between Royal Arms and other weapons as needed—don’t rely on Royal Arms exclusively.

Final Thoughts: Royal Arms Are Worth It!

Many players avoid Royal Arms due to self-damage, but once you understand how they work and how to manage their drawbacks, they become some of the most powerful weapons in the game. Their high damage output, unique attack animations, and ability to bypass enemy resistances make them invaluable.

If you’ve previously avoided Royal Arms, give them another shot using the strategies outlined in this guide. With a bit of practice, you’ll be able to wield them efficiently without worrying about constant health depletion.

Happy hunting, and may your Warp Strikes be calculated!
