To help you build the most effective defense, we’ve broken down every unit in the game into tiers from S to F based on their current performance, rarity, and utility in various scenarios. This tier list is based on in-game testing and community feedback, and within each tier, units are listed from strongest to weakest.

Stud Tower Defense Tier List

S Tier – Top Picks (Best of the Best)

These units are considered essential in almost every strategy. Whether due to high damage, utility, or synergy, they are the core of a powerful defense setup.

• Magmamancer (Epic)
• Grappler (Common)
• Shopkeeper (Epic)
• Zeus (Legendary)
• Gunner (Common)
• Echo (Celestial)

These units offer a mix of reliable crowd control, DPS, and utility, making them extremely effective across all game modes.

A Tier – Strong and Reliable

Great choices for most stages. While not as dominant as S-Tier units, these towers still deliver excellent results when used well.

• Archer (Common)
• Viper (Celestial)
• Knife Dealer (Epic)

These units can form the backbone of a solid defense, especially when you lack access to S-tier picks.

B Tier – Situational Picks

Good in specific setups or early game stages, but generally less efficient than higher tiers in tougher scenarios.

• Rain Dancer (Rare)
• Boxer (Rare)
• Greatsword (Rare)

B-tier towers can still shine when placed strategically but often need support from stronger units.

C Tier – Mediocre Performance

These units have limited value. They might work in early-game or themed challenges, but they’re typically outclassed by higher-tier options.

• Pyromancer (Uncommon)
• Cowboy (Epic)
• Golden Monkey (Celestial)
• A Bad Dream (Legendary)
• Ballista (Uncommon)

While some of these may look promising due to their rarity, their actual impact in-game falls short.

D Tier – Weak Choices

Mostly underwhelming units that don’t offer much value in combat. Avoid using them unless you’re experimenting or have no other options.

• Necromancer (Epic)
• Grenadier (Rare)
• Grug (Rare)
• Butcher (Rare)

These towers either lack damage, range, or utility, making them hard to justify in most team comps.

F Tier – Not Recommended

These are the weakest towers in the current meta. They bring little to no value in actual gameplay.

• Trapper (Uncommon)

Unless you’re testing for fun or completing a challenge, it’s best to avoid deploying F-tier units.

The meta in Stud Tower Defense is always evolving as updates and balancing tweaks roll in. While this tier list offers a solid overview of the current top performers, your choice of units should also depend on your playstyle, map, and team composition. That said, investing in S and A tier units will give you the best chance of success in most situations.
