Roblox ASTDX 3 Update Guide – New Units Showcase & Tier List

The latest update in All Star Tower Defense X brings several new units along with gameplay changes that shift how the game is played. Instead of relying purely on raw damage, this update leans more into mechanics, timing, and team synergy. If you haven’t played in a while or you’re just starting out, this guide will help you understand the new units, how they work, and which ones are actually worth using.

New System Changes You Should Know

One of the biggest differences in this update is the removal of traditional evolution for many units. Instead, most of them now use an Ascend system, which gives a small stat boost (around 20%) along with minor improvements. There are also a few limitations:

• Some units cannot be retraced
• One-placement units have stricter restrictions
• Certain characters rely heavily on mechanics rather than raw stats

Because of this, team composition matters more than ever.

Token Unit – High Damage with Complex Mechanics

Token is easily one of the most complicated units in this update. It uses a swap system between two forms: Kitty and Sun Kokun.

Here’s how it works:

• After several attacks, you can swap forms
• Each form gives different bonuses
• Repeated swapping unlocks stronger transformation states

Main forms include:

• Kitty Mode: boosts damage and special effects
• Sun Kokun Mode: improves attack speed and applies slow

After enough swaps, Token can evolve into:

• Field A: critical-based attacks with counter damage
• Field B: additional attacks but with possible drawbacks

If you fully upgrade and manage the swaps correctly, Token reaches a final form with:

• Extremely fast attack speed
• Strong scaling damage
• Extra summon abilities

However, the downside is clear. This unit is powerful, but the mechanics are not beginner-friendly and can feel frustrating if misplayed.

Summer School Wonder – Top Tier Support Unit

This unit stands out as one of the best supports in the current update.

Instead of dealing damage, it focuses on boosting your entire team with abilities such as:

• Increasing ally damage significantly
• Applying burn effects across the map
• Providing temporary immunity buffs
• Increasing income from kills and farming

Even though its personal damage is low, the overall impact on your team is massive. It works especially well in:

• Long survival runs
• High-level content
• Teams built around DPS units

Right now, this is one of the most valuable units to have.

Stitch Mister – Scaling DPS with RNG Elements

Stitch Mister is a damage-focused unit that builds strength over time.

Its main mechanic revolves around stacking:

• Every few kills increase damage and speed
• At max stacks, it enters a special random mode

These modes include:

• Calm State: more range, crit chance, and stable output
• Crazed State: faster attacks with extra hits

It also deals AOE lightning damage, making it useful against large waves.

The main drawback is consistency. Since the final state is random, performance can vary between runs. Still, once fully stacked, the damage becomes very strong.

Quick Tier List Overview

Here’s a simple breakdown of how the new units perform right now:

• S Tier
  Summer School Wonder – Best support in the current meta
• A Tier
  Token – Very strong but requires skill and timing
• B Tier
  Stitch Mister – Good damage but needs setup and luck
• Situational Tier
  Older units that haven’t adapted to the new system

This list may change over time, but it’s a solid starting point for now.

Tips for Using the New Units

To get the most out of this update, keep these points in mind:

• Build a balanced team instead of relying on one unit
• Use support units to boost overall performance
• Only use Token if you understand its mechanics
• Focus on long-term scaling rather than early damage

This approach will help you stay consistent across different modes.

This update makes All Star Tower Defense X feel more strategic and less dependent on simple upgrades. Each unit now has a clear role, and understanding their mechanics is key to progressing further. If you enjoy experimenting with builds and learning new systems, this update offers plenty to explore. Take your time, test different combinations, and find what works best for your playstyle.
