UR Child Emperor - Core UR

How to get UR Child Emperor?

As always, it is not recommended to skip core units. Get it if you can.

KEEPSAKE

Ironically, KS is not really recommended since the +40% block doesn’t do much (as explained it only applies to normal base damage). Of course the extra +10% block rate is good, and the option to 5P, but for F2P is really not needed. Better to save your resources for UR DK. For whales/PVP competitive, you definitely want the KS and 5P.

Let’s break down this core’s mechanics—its strengths and weaknesses.
Essentially, this is a more advanced and "heavier" version of the Bomb core, now with extra mechanics. It centers around two key stats: Block and Tenacity. At the bottom of the purple shield icons, you'll see a number like "x1". This number indicates the percentage of max HP the shield holds. For example, x1 = 100% HP, x2 = 200%, etc.

Since each point of shield absorbs 10 damage, x1 equals 10x your max HP in total absorption. So x3 would absorb damage equal to 30 times your unit’s max HP.

Weakness of Block

Block only reduces basic attack damage. It does not affect DoTs, extra damage effects, or similar sources. However, in this case, the goal is not how much damage we reduce—it's simply to trigger Block, which grants Tenacity, and that in turn restores Specialized Resilience.

That’s why Block RATE is the stat that matters here—not the Block value itself.

• Block RATE = Chance to block an attack

• Block = How much damage is reduced when a block happens

About Tenacity and Shield Recharge

Although the initial 150% Tenacity granted at the start of battle does not scale with Shield Rate, any Tenacity gained later does benefit from it. This means Tenacity helps recharge the purple shields, up to a cap of 5x max HP.

Example:
If normal TTM casts an ultimate and gives 20% Tenacity, and you have Alloy+ on the team providing +70% Shield Rate, the 20% becomes:
20% × 1.7 = 34% Tenacity
That means your shields regenerate faster.

⚠️ Important: The purple shields are not classified as Tenacity or Resilience. So Lightning Genji’s buff that enhances Tenacity/Resilience has no effect on these shields.

Another Bonus Mechanic

Even if UR CE dies, the core effect persists. Allies will still be able to block attacks and recharge shields as usual.

So, how should we build around this core?

Use characters that:

• Boost Shield Rate

• Grant Tenacity

• Increase Block RATE

Recommended Characters:

• Alloy+ → +75% Shield Rate at 5★

• Melz+ → +50% Shield Rate + Rebirth effect

• Tank Top Vegan → Budget pick, +70% Shield Rate at 5★

• Gouketsu → +70% Shield Rate for 2 rounds in a cross shape

• Amai+ → +30% Shield Rate at the start

• TTM w/ KS → Grants 30% Tenacity

• Bang (Silverfang) → +30% Block RATE and +7% Tenacity when blocking

• Hellfire Flame → Grants 20% Tenacity to his column at the start of each round

Additional Tips:

• Shields scale off Max HP, so units with HP buffs are great:

  • WDM → +25% HP for the column

• Emblems:

  • Use Undying Emblem for free Tenacity (upgrade it to Ultimate for best effect)

  • Upgrade Eternal Heart fully – it adds a significant amount of Block RATE

• Talents:

  • Offense: Use Piercing Sigil to reduce the chance of your attacks being blocked

  • Defense: Use Vitality for more shield generation (based on HP) or Bastion for stable defense

• Gear: Tanks in this core setup should now prioritize x3 Block RATE

• Damage-sharing allies like MG Mosquito or Gouketsu help distribute incoming damage across the shields

• Let UR CE move first (via SPD gear or pairing with Speedster) so he can ult early and grant Block RATE to allies

• Upgrade the core level ASAP, as each level brings massive bonuses:

Core Scaling:

• Level 4: 180% Tenacity (Max HP), 11 damage absorbed per shield point

• Level 10: 210% Tenacity (Max HP), 12 dmg per point

• Level 17: 250% Tenacity (Max HP), 13 dmg per point
