How to Unlock and Evolve the Universal Tower Defense Z Shiny Gremmy

If you want to completely dominate the hardest raids and legend stages in the game, obtaining the Universal Tower Defense Z shiny Gremmy is the ultimate goal. As an Unrivaled rarity unit, the Universal Tower Defense Z shiny Gremmy boasts some of the most overpowered mechanics currently available, including the ability to spawn clones and unleash massive area-of-effect (AoE) damage.

However, getting your hands on this incredibly rare unit and evolving him into his true "Visionary" form takes serious dedication and a solid farming strategy. From navigating the Special Banners to grinding out Universal Fragments in Sky Tears, the path to maxing out this unit is complex. In this comprehensive guide, we will break down everything you need to know about unlocking, evolving, and optimizing this top-tier unit so you can carry any lobby.

Unlocking the Base Unit and Shiny Variant

Before you can evolve him, you need to pull the base version of Gremmy. He is classified as an Unrivaled unit, which makes him exceptionally difficult to obtain through standard means. Players will need to focus their gems on the Special Banner or Universal Festival Banners.

To get the Universal Tower Defense Z shiny Gremmy, you have to beat the odds twice. First, you must hit the 0.1% drop rate for an Unrivaled unit. Then, you must roll the shiny variant, which drastically alters his cosmetic appearance and provides a unique status symbol. Player experience suggests that having the Shiny Hunter gamepass is practically mandatory if you are seriously hunting for this variant, as it removes the level 10 requirement and boosts your overall shiny luck.

Special Banner Drop Rates

Here is a breakdown of the drop rates you will encounter when pulling on the Special Banner for Gremmy:

Farming Evolution Materials

Once you have secured the unit, the real grind begins. Evolving the Universal Tower Defense Z shiny Gremmy requires specific fragments scattered across various game modes. Community reports indicate that farming these materials can take hours, especially if you attempt to solo the content.

You will need to gather shards from Raids, time-limited Events (like the Hollow Destroyers vs. Reapers event), and Sky Tear legend stages. The most notorious item required for his evolution is the Universal Fragment.

Fragment Locations and Crafting

If you are struggling to get the Universal Fragment to drop directly from event currencies (which costs around 1,200 event points), you can craft it by speaking with the Trickster NPC in the Upgrades area.

Pro Tip: Always utilize Global Matchmaking when grinding Sky Tears or Raids. Bosses in these modes often have upwards of 100 million HP, and playing with a full lobby ensures you clear the stage in minutes rather than failing near the end.

Gremmy's Visionary Kit and Clone Mechanics

What makes the Universal Tower Defense Z shiny Gremmy an absolute monster on the battlefield is his intricate "Visionary" passive kit. First and foremost, he is completely immune to stun, making him reliable against bosses that spam crowd control.

His most defining feature is his Imagination Clones. Every other attack spawns a clone (capped at three). These clones copy 50% of his damage and 50% of his range. When a clone despawns after 20 seconds, it applies a 3-second stun to all enemies in its range.

Active Attack Modes

Unlike standard units that just upgrade their base attack, Gremmy features a "Materialization Arsenal." Using his active ability allows you to swap between different attack styles depending on the situation.

Maximizing Damage: Stats, Traits, and Relics

To get the most out of your Universal Tower Defense Z shiny Gremmy, you need to invest in his base stats and traits. Because he scales so well with damage, you want to ensure his stat ranks are as close to SSS as possible.

If you roll a terrible damage stat on Gremmy, you can use the Stats Transfer mechanic. By paying 100,000 Gold, you can transfer an SSS Damage rank from a fodder unit directly onto Gremmy. Additionally, rolling for a top-tier trait like "Ruler" or "Visionary" will exponentially increase his damage output.

Recommended Relics and Status Effects

Equipping the right Relics is crucial. Since Gremmy applies multiple status effects, you want to build around his elemental strengths and debuffs. Relics can be farmed from Story Modes (Top/Bottom pieces) and the Virtual Realm (Accessories).

Etherealizing and AFK Grinding

To push your Universal Tower Defense Z shiny Gremmy to the absolute limit, you must Etherealize him. Etherealizing requires sacrificing duplicate units or using Etherealization shards of the same rarity. Reaching levels 1, 3, and 5 grants an additional 10 stat points each, while levels 2, 4, and 6 unlock powerful passive buffs.

If you find yourself short on XP to reach the maximum level of 70 (which requires 72,393 XP), you should take advantage of the AFK World. The AFK chamber allows you to passively run stages you have previously cleared. If you hold Premium or VIP status, your clear times are multiplied faster, allowing you to stockpile XP and gold while you sleep.

Frequently Asked Questions

How do I get the Universal Tower Defense Z shiny Gremmy? You must first pull his base Unrivaled unit from the Special Banner (0.1% chance) and get extremely lucky to roll his shiny variant. Having the Shiny Hunter gamepass significantly improves your chances of obtaining the Universal Tower Defense Z shiny Gremmy.

What is the best attack mode for Gremmy? It depends on the wave. "Galaxy Void" is incredible because it turns him into a Hybrid unit with a circular AoE that slows enemies. However, for pure single-target boss damage, "Spiritual Steel" is preferred due to its heavy Bleed effect.

Why can't I buy the Universal Fragment in the event shop? Community reports note a common bug where players have the required 1,200 currency but the purchase fails. If this happens while trying to evolve your Universal Tower Defense Z shiny Gremmy, try switching lobbies or completing one more quick stage to force the server to update your inventory cache.

Is Stats Transfer worth the gold? Yes. Transferring an SSS rank stat costs 100,000 Gold, but it prevents you from having to endlessly reroll stats on an incredibly rare unit. Just remember that the unit you take the stats from will be reset to level 1 and lose all its traits.
