Our take on Imperator's regalia

“Earned in the Weekly raid”

+14% damage to bosses plus +8% damage makes it the best set for the Trials and the Weekly Raid, and -8% Blessing cooldown helps in long boss fights. The catch is access: its tagline says “Earned in the Weekly raid” and every piece is “Sold by Umbra”, so you need all four Trials cleared before you can even start on it.

What does the Imperator's regalia set bonus do?

+14% Damage to bosses

Extra damage against bosses only. It pays off in the four Trials, the Weekly Raid and boss rounds such as Cerberus at round 20, and does nothing against normal waves.

+8% Damage

A flat damage increase for everything you do, the same kind of bonus as the Gladius node Sharpened Edge (+2% per rank).

-8% Blessing cooldown

Your Blessing comes back sooner. Our Whirl Cut showed an 8.4 s cooldown and Piercing Pilum 9.8 s, so a few percent means noticeably more casts over a long Survival run.

+28 Vitality and +140 Max HP

On our level-1 Gladiator with 124 Max HP, the set’s +140 Max HP alone would be a 113% increase. Every set adds flat health that scales with rarity. Mythic sets give +28 Vitality / +140 Max HP, against +23 / +115 for Legendary.

The set’s own tagline is “Earned in the Weekly raid”. The raid (Hydra of Lerna Extreme) opens only after you clear all four Trials, which need level 10. See the Trials & Weekly Raid guide.

Mythic gear can also come from chests. These are the chests that can roll Mythic items:

ChestMythic chanceArmor / weapon splitPrice
Epic Chest5%Armor 60% · Weapon 40%3,200 Cash or 99 Robux
Legendary chest15%—not sold (from codes and rewards)

A chest that rolls Mythic still picks one item from every Mythic armor and weapon, so a specific piece of Imperator's regalia is much rarer than the Mythic chance. The Epic Chest shows the split for Mythic rolls: “Weapons 1.7% · Sets 0.83% each”.

Who should use Imperator's regalia?

  • Trials, Weekly Raid and boss rounds: +14% Damage to bosses, +8% Damage.
  • Long Survival runs: +8% Damage.
  • Blessing builds (Numen path): -8% Blessing cooldown.

How to build around Imperator's regalia

Trials, Weekly Raid and boss rounds. Boss bonuses matter in the four Trials (from level 10), the Weekly Raid and boss rounds such as Cerberus at round 20. The Gladius capstone Executioner (+20% damage to foes below 30% health) speeds up the end of every boss fight.

Long Survival runs. For long Survival runs, pick boons that match the set, never leave early (the result bonus drops to x0.50), and push past round 21, where Forge Embers start dropping for your next Legendary or Mythic set.

Blessing builds (Numen path). Blessing builds start at the Crystal of Fortuna: two slots are free, and Lucky spins give a 12% Legendary chance. From level 15, the Numen path adds Blessing damage (Inner Fire, +3% per rank) and its capstone Will Of The Gods turns every Blessing hit into cooldown.

Fit: our reading of the bonus Based on the class cards and skill tree we saw in game, not on damage tests.
