How to Get Unbound Chrollo (Spider Boss) in ASTD X Guide

If you’re playing All Star Tower Defense X (ASTD X) and aiming to collect some of the rarest units, then Unbound Chrollo, also known as the Spider Boss, should be on your radar. This limited unit is currently one of the hardest to obtain in the game and comes with some powerful abilities that make it worth chasing. Here’s how you can get your hands on it and what to expect once you do.

Where to Find Unbound Chrollo

• To get Unbound Chrollo, you’ll need to focus on Banner X.
• This is important — do not waste your time in Banner Y or other banners.

The unit is only available through Banner X, and the chance of pulling it is extremely low at just 0.01%. Yes, that means it’s one of the rarest units in the game right now. Since it’s such a rare pull, be prepared to grind heavily. You’ll need plenty of gems and luck to summon him. Make sure you’re farming efficiently, completing daily missions, and staying updated with any limited-time banner rotations.

Is Unbound Chrollo Worth It?

Absolutely. If you’re wondering whether it’s worth the grind — the answer is yes. Once fully upgraded, Unbound Chrollo deals impressive AoE damage and comes with strong utility for higher wave runs. His range and skill effects are designed to handle large groups of enemies, making him a solid pick for both early game and late game strategies.

Unbound Chrollo is rare, strong, and definitely a flex unit in ASTD X. If you’re a collector or want to stay competitive in harder modes, start grinding now while he’s still available in the banner.
