One of the main objectives of FFXV is for Noctis to gather the royal arms. These weapons have a lot of in-game lore behind them... but they don't seem all that powerful.
Royal arms drain your health each time you strike an enemy, sometimes have other adverse effects (Axe of the Conqueror greatly reduces defense just by having it equipped), and seem to not gain the damage type bonuses you would expect for a weapon of that class.
Why would I want to have one active?

Aside from boosting your stats exponentially, there are two benefits for using the Royal Arms:
Deals non-specific weapon type damage, which are useful against enemies who have physical resistances. i.e. The Katana of the Warrior functions with mobility and style of a sword, but deals regular damage to enemies who have resistance or weakness to swords.
Enhances Warp Strike, Blitz Combos, and/or Directional Attacks to make them more powerful and effective by giving them additional abilities. iDigitalTimes Royal Arms contains a breakdown of each of the Royal Arm's hidden abilities

The biggest reason to user royal arms are the stat boosts. A very viable and highly suggested strategy is to equip 3 royal arms and one actually "used" weapon or spell, to maximize the stat bonuses. Personally, I use the sword of the father and Axe of the conqueror in two slots as they increase str, which increases Noctis' dmg per hit. I then use the star of the roue just to have a ranged option, but Sword of the Wise is a good option for well rounded stats, and shield of the just is great for HP and defense, but it takes away stength. If your have built as a mage, there are arms such as the Scepter of the Pious that give a bonus to magic, and even uses magic for its normal attack damage.
They are also useful against enemies who are resistant to elements and/or weapon types. Royal arms all have no elemental affinity and also do not "count" as any weapon type for damage resistance. So if an enemy has two handed sword resistance, you can use the Sword of the Tall, or Axe of the Conqueror royal arm, you will bypass that resistance.
As a side not, if the enemy has an elemental resistance you want to exploit, but has weapon resistances that dont make you happy, you can use Ignus' Enhancement ability on your royal arm to give it the elemental damage bonus while still avoiding the weapon resistance of the enemy.
I just found out a little secret behind the notoriosly mediocre royal arms after equipping four at a time. Not only does it boost my stats, but somehow, when I have 4 royal arms equipped, Noctis can't be hit by projectiles. It looks like Noctis is being shielded with tiny royal arms and I can prove it as I tried only 3 (katana, shield, star) and it didn't work. When I added the Sword of the Father, I started getting the effect. I'm still testing other combinations, though.
EDIT: so ive just tested it. Turns out, you only need the sword of father equipped for the bladeguard(that would be what ill call it now) To work.
EDIT 2: ive tested all arms already. Turns out, all royal arms has bladeguard. And only royal arms. I could be wrong but, as i test these, im using the kingly raiment. It could be the suit+arms.
1equip the best get for stat boosting solely. i havent found them overly useful for combat, but you can get some epic set ups to buff primary use weapon
