How to Unlock The King in Universal Tower Defense Z

Your journey to mastering Universal Tower Defense Z Yhwach begins by obtaining his base form, The King. This unit is a potential reward from the Moonless Sky Rift, an endgame Tear stage accessed through the Universal Tear portal located behind the World Train building. You can run this stage solo or in a group of four.

To give you a clear picture of the grind ahead, here are the drop rates and pity systems for the Moonless Sky Rift:

Item / Unit Drop Rate Pity Guarantee
The King (Base Unit) 6% 25 completions
Blade of the Patriarch 10% 15 completions
Infused Spirit Blade 10% 15 completions
Boundless Orb 2% 40 completions

The pity system ensures you won’t be stuck in a permanent dry spell. If you are exceptionally lucky, you might even receive the Shiny variant of the unit. Remember that the pity count resets once an item drops, so the Boundless Orb often becomes the primary gatekeeper for the evolution process. If you want to maximize your efficiency, keep running the Rift until you have all the necessary materials.

Evolution Requirements for The Almighty King

Once you have The King in your inventory, the next step is evolving him into The Almighty King. This evolution requires a specific set of materials that you will gather from the Rift, merchants, and challenge maps.

Material Quantity Needed
Universal Fragment 5x
Phantom Fragment 6x
Ocean Fragment 12x
Blade of the Patriarch 1x
Infused Spirit Blade 1x
Boundless Orb 1x
Gold 50,000

Fragments can be purchased from the Virtual Merchant and the standard Merchant, or earned by completing Challenge maps. Gold is the standard in-game currency that you will naturally accumulate from clearing stages. Once you have gathered everything, simply navigate to the Evolutions menu, select The King, and hit the “Evolve!” button to unlock the full power of Universal Tower Defense Z Yhwach.

The Almighty King Forms and Passives Explained

The ultimate power of Universal Tower Defense Z Yhwach lies in his unique Active Ability called The Almighty. This ability allows him to swap between two distinct forms mid-match: Self Buff and Other Buff. The choice you make heavily dictates your strategy for that specific run.

Active Ability: Reishi Manipulation

Before you choose a form, every version of The Almighty King applies Blue Burn for 20% of his damage to every unit in range for 5 ticks with every attack. This built-in DoT is the engine that drives his best damage builds.

Self Buff Form (The Almighty King)

When you select the Self Buff form, Yhwach becomes an absolute powerhouse. Based on community reports and high-level playthroughs, this form turns him into a primary damage dealer.

Passive: All-Seeing Eye (Self Buff)

  • For every owned unit in his range, those allies receive -20% Damage and -20% Range. However, The Almighty King gains +35% Damage per unit (capping at 150%).
  • On attack, the unit makes a Follow-up Attack for 100% Damage, effectively doubling his damage output.
  • When stunned or debuffed, the unit removes the effect and applies it to a random ally in its range. The unit also gains +50% Damage for 10 seconds.

This form creates an interesting dynamic where you want units in his range to power him up, but you need to be careful about the penalties they incur. Players often place high-value buffers or expendable units near him to maximize the damage buff.

Other Buff Form (Support King)

This form turns The Almighty King into arguably the best support unit in the game. He intercepts all debuffs from his allies, acting as a tanky buffer.

Passive: All-Seeing Eye (Other Buff)

  • When an ally in range gets a Debuff, the ally gains +50% Damage for 10 seconds. The Almighty King takes the debuff onto himself.
  • The unit provides drastically different buffs depending on the game mode you are playing.
Game Mode Buffs Provided to Allies
World Raid -30% Cost, +40% Damage, +30% Elemental Damage, +100% Boss Damage
Rift +55% Damage, -10% SPA
Ultra Boss +40% Damage, +50% Hyper Armor Damage, +75% Boss Raid Damage
Raid +45% Hyper Armor Damage, +50% Damage
Infinite +2.5% Damage per Wave (Cap: 200%), -1% SPA per Wave (Cap: -10%)
Other Game Modes +45% Damage

The versatility of Universal Tower Defense Z Yhwach allows you to freely switch between forms using the 30-second cooldown on the Active Ability. This means you can start a game in Other Buff form to strengthen your setup, then swap to Self Buff for final boss pushes.

The Best Build for Yhwach in Universal Tower Defense Z

When constructing your build, the community strongly agrees that his personal Almighty Set is the definitive choice. While many damage sets exist, the synergy of this specific gear with his kit is unmatched.

Why the Almighty Set Works: The set has a unique drawback and massive upside. The unit can no longer crit, but all buff gains are increased by 30% (excluding relic and trait buffs). Since Yhwach relies heavily on his Blue Burn DoT and his ability to give/receive buffs, losing critical hit chance is a welcome trade-off for the raw power the set provides.

Set Bonuses & Stats:

  • +15% Damage, +10% Range, +25% Damage, +30% DoT Damage
  • Unique Passive: Whenever this unit applies DoT, grants 45% Damage for 10 seconds. (Cannot stack, but easily maintained permanently with his attack speed).

Stat Priority Table:

Slot Primary Stat Priority Substats
Headpiece Damage / Elemental Damage Cooldown, DoT Damage
Accessories Almighty Set Pieces Cooldown, DoT Damage, Buff Potency
Relic Ruler Trait S / SS Stat Grade

Trait and Grade Recommendations:

  • Trait: Roll for the Ruler trait. It provides the best overall damage and utility scaling for a hybrid unit.
  • Stat Grade: Aim for S tier or higher. The multiplicative scaling on his buffs and DoT makes high stat grades mandatory for endgame content like World Raids and Infinite modes.

Player experience shows that a fully built Yhwach with the Ruler trait and SS stats can easily hit over a million damage per follow-up attack. Focus on cooldown and DoT substats to maximize his uptime on the 45% damage set proc.

Gameplay Tips and Synergies

Bringing Universal Tower Defense Z Yhwach into your team changes the entire dynamic of your strategy. He is not just a damage dealer; he is a force multiplier.

Best Game Modes:

  • Infinite Mode: The Other Buff form is completely broken here, granting scaling damage and SPA reduction every wave.
  • World Raid: Provides massive cost reduction and boss damage to your entire team.
  • Ultra Boss: The combination of Hyper Armor Damage and Boss Raid Damage makes him a must-pick.

Team Composition: Pair him with other DoT units to maximize his set passive. Since he applies Blue Burn, he synergizes well with units that have debuff-enhancing passives. If you run him in Self Buff form, a single strong tank like Ichigo can stand in his range to absorb the stat penalties while feeding Yhwach his massive damage boost.

Pro Tip: Start every match in Other Buff form to get your team established and reduce costs. Switch to Self Buff during boss waves to delete priority targets. With a 30-second cooldown, you can adapt your strategy fluidly throughout the match.
