What Are Orbs in Roblox All Star Tower Defense?

If you’re new to All Star Tower Defense, orbs are equippable items that supercharge your units with massive stat boosts. Think of them as the difference between a regular unit and an absolute monster that melts through enemies. You can only equip one orb per unit, and you can only own one of each orb type (except Water Orbs).

S+ Tier Orbs – The Meta Definers

Ultra Magic Orb

Effect: Initial RNG 20%, Overall DMG Buff 5%, Overall Cost Reduction 7%
Obtained: Random Boss Rush 2 Raid
Works On: All Units
Why It’s S+ Tier: The only orb that buffs literally everything. That 5% damage boost compounds with each upgrade, making maxed units absolutely devastating. The cost reduction lets you deploy faster, while the range boost ensures better coverage.

Super Blueeye Orb

Effect: Initial RNG 40%
Obtained: Prestige (Relic)

How to Get Orbs in Roblox ASTD?

I’ve spent countless hours farming orbs, and here’s the most efficient path:

1. Farm Mode Materials

Head to the FARM mission in the Infinite/Trials building. Every enemy drops random crafting materials – it’s RNG, but consistent grinding pays off.

2. Orb Shop Crafting

Most orbs require specific material combinations. For example:

Prey Eye: 1350 Unknown DNA + 1350 Silver + 1350 DualTooth + 1750 Gems
Snake Orb: 1350 Leafs + 1350 DualTooth + 1350 Unknown DNA + 1750 Gems

3. Trials and Raids

Some of the best orbs drop directly from extreme difficulty content:

Trial 2 Extreme: Bomba Orb
Trial 3 Extreme: Cost Orb
Raid 3 Extreme: Universal Reduction Orb

4. Special Challenges

Unique orbs like Fire Rage come from specific challenges. These are often time-limited, so jump on them when available!

Pro Orb Strategies for 2025

After mastering the orb system, here are my top strategies that separate good players from great ones:

The Economy Rush Build

Combine Universal Reduction + Cost Orb + Prey Eye on your money units. You’ll have your full team deployed while opponents are still saving for their second unit.

The Range Supremacy Setup

Super Blueeye + Blueeye + orbs with Initial-RNG bonuses create units that cover entire maps. Perfect for lazy farming infinite mode.

The One-Shot Wonder

Fire Rage + unit-specific damage orbs can create opening gambits that instantly delete early waves, giving you a massive economic advantage.

Common Orb Mistakes to Avoid

I see these errors constantly, even from experienced players:

1. Wasting Universal Orbs on Weak Units

S+ tier orbs like Ultra Magic should ONLY go on your absolute best units. Don’t waste them on temporary team members.

2. Ignoring Unit-Specific Requirements

That God Heart orb won’t do anything on your Onwin. Always check compatibility before equipping!

3. Hoarding Instead of Using

I get it – you want to save that Fire Rage for the “perfect” unit. But using it now to progress faster often leads to better rewards than waiting.

4. Neglecting Cost Reduction

Damage is flashy, but economy wins games. Don’t underestimate cost reduction orbs, especially in infinite mode.

ASTD X Update – What’s Changed?

With All Star Tower Defense X launching, many players wonder about orb changes. While ASTD X features a completely new orb system with Skill Trees, classic ASTD maintains its traditional orb mechanics.

Frequently Asked Questions

Which orb should I craft first as a new player?

Start with Prey Eye – it’s affordable, works on all units, and provides a nice all-around boost while you farm for better options.

Can I remove orbs from units?

No, once equipped, orbs are permanently attached to that unit. Choose wisely!

Do orbs stack with each other?

Different orbs stack their effects, but you can only equip one orb per unit. Plan your combinations carefully.

Are Water Orbs worth using?

Only in very specific infinite mode strategies. For 99% of content, any other orb outperforms Water Orbs significantly.

What’s the drop rate for raid orbs?

Extreme raids have approximately 20% drop rates for exclusive orbs. Expect to run them multiple times.

Should I save gems for orb crafting?

Absolutely. Once you have a solid unit roster, investing gems in orbs provides the biggest power spike.

Which units benefit most from Universal Reduction?

High-cost 6-star units and money generation units see the biggest improvements from cost reduction.

Orb Tier List Summary

The ASTD orb meta in 2025 heavily favors universal orbs that work on any unit. Ultra Magic, Super Blueeye, and Universal Reduction remain the undisputed kings, while newer additions like Azure Orb shake up the A-tier rankings. Remember – even the best orb can’t save a weak unit, so always prioritize getting strong characters first before investing in orbs.

Whether you’re pushing infinite mode records or just trying to beat that annoying story chapter, the right orb setup makes all the difference. Start with budget options like Prey Eye, work your way up to crafting S-tier orbs, and always match orbs to your playstyle.

Keep grinding, keep experimenting, and most importantly – have fun defending! The ASTD community continues to discover new strategies daily, so don’t be afraid to try unconventional orb combinations. Who knows? You might discover the next meta-breaking setup.
