How to Get the Colossal Titan in Attack on Titan Revolution (Ultimate Guide)

Understanding the Colossal Titan

The Colossal Titan is widely considered the strongest and rarest Titan Shifter in Attack on Titan Revolution. Unlike other Shifters that may offer mobility or hybrid utility, the Colossal Titan is built for one specific purpose: devastating, screen-clearing power. It is the largest Shifter in the game, capable of eliminating Pure Titans simply by walking over them.

Its kit is centered around "Atomic Ascension," a massive AoE nuke that, when combined with full Awakening and max mastery, can clear raid phases and waves instantly. While it lacks a healing roar—making it distinct from other Shifters—its unparalleled ability to output damage in PvE content makes it a top-tier choice for endgame players.

Prerequisites for Unlocking the Colossal Titan

Before you attempt to grind for the Colossal Titan, you need to ensure your account meets the strict entry requirements. Attack on Titan Revolution enforces these barriers to prevent under-geared players from failing high-difficulty raids.

• Prestige Level: You must be at least Prestige 2.
• Gear Rank: Your average gear rank must be A- or higher.
• Family Restriction: Ensure you are not using the Zoe, Ackerman, or Helos families. The Colossal Serum will not function if you are using these specific bloodlines.
• Access: You must have access to the lobby raid queue.

If you do not meet these criteria, the raid queue will not accept your entry. If you are currently under-geared, focus on leveling your Prestige and upgrading your gear through lower-tier missions before attempting this grind.

How to Unlock the Colossal Titan: The Raid Process

The Colossal Titan is unlocked by obtaining the Colossal Serum, which drops exclusively from the Colossal Titan Raid on Aberrant difficulty. This raid is mechanically complex and requires coordination.

1. Enter the Raid: Queue for the Colossal Titan Raid on Aberrant difficulty. A party of four is highly recommended for efficiency.
2. Phase 1 (Cannon Duty): You cannot damage the Colossal Titan with blades in this phase. One player must focus on operating the wall cannons to reduce the Titan's HP by 50%. The remaining players must defend Eren from waves of Pure Titans.
3. Phase 2 (Direct Combat): Once the Titan's HP reaches 50%, it will breach the wall. Switch to direct combat. Use AoE damage perks and, if available, leverage the Shiki family buff to boost output and maintain knockback immunity.
4. Looting: Upon completion, ensure you clear both the Free Raid Chest and the Emperor's Trove. The Colossal Serum has a low drop rate, so maximizing your chest openings per run is essential.

Optimizing Your Serum Farm

Because the drop rate for the Colossal Serum is quite low (typically ranging from 0.20% to 0.60% depending on your chests and luck modifiers), most players will need to run this raid dozens, if not hundreds, of times.

Team Composition Strategy

Solo farming is possible, but it is inefficient. A solo run can take 5–10 minutes and carries a high risk of failure. A coordinated team of four can clear the raid in 1.5–3 minutes. For the most effective farm:

• 1 Dedicated Operator: Focuses solely on the wall cannons during Phase 1.
• 2–3 AoE Damage Dealers: High-level players (Prestige 4–5+) with A+ gear to clear Pure Titans and maximize Phase 2 damage.
• Ground Clearer: Protects Eren to ensure the mission does not end prematurely.

Increasing Efficiency

To speed up your grind, prioritize "Luck" boosts before starting your raid sessions. Additionally, keep an eye out for "Titan Cards." Recent game updates have introduced these cards to allow players to shortcut mastery leveling. Using these cards can quickly take your Titan from level 3 to level 13, saving you hours of repetitive grinding.

Building the Perfect Colossal Titan

Once you have successfully obtained and consumed the Colossal Serum, your build will determine your effectiveness. The Colossal Titan is not a jack-of-all-trades; it is a specialist.

Arlert Family

The best-in-slot choice for the Colossal Titan. It provides +10% Colossal stats, +20% Nuke AoE, and includes Shifter Regen. This is the only family that directly expands the radius of your nuke.

Fritz Family

A strong alternative focused on pure damage output. This is an excellent choice for team-oriented players who want to maximize their contribution during raid boss phases.

Essential Artifacts and Skills

Equip the Colossal Scars artifact. This item is a raid drop that increases your Colossal Titan stats by 15%. For your skill tree, invest 100% of your nodes into damage. Do not attempt a hybrid defensive build; the Colossal Titan relies on its ability to "one-shot" raid phases. Always aim to fill your Awakening bar completely before shifting to ensure you get the maximum mushroom-cloud AoE effect.

Is the Colossal Titan Worth the Grind?

The decision to grind for the Colossal Titan depends on your playstyle. It is arguably the most powerful PvE asset in the game, but it comes with distinct trade-offs.

If you are looking for a Shifter to carry you through high-difficulty raids and farm materials efficiently, the Colossal Titan is the definitive choice. However, if you prioritize mobility or consistent PvP performance, you may find the Attack Titan or other Shifters more versatile. The Colossal Titan is a "nuke"—use it when you need to delete everything on the screen, not when you need to outmaneuver an opponent.

Frequently Asked Questions

How long does it take to unlock the Colossal Titan?

There is no guaranteed timeframe due to the RNG nature of the drop. Most players report receiving the serum within 30 to 80 successful raid clears. Some exceptionally lucky players may see it in under 10 runs, while others may require over 150.

Is the Colossal Titan free to unlock?

Yes. You do not need to spend Robux to acquire the Shifter. While gamepasses (such as the +1 Drop Gamepass) can increase your efficiency, the entire process is achievable through free-to-play grinding.

Does the Colossal Titan have any new moves?

Yes, recent updates have introduced new abilities and improved the UI for the Colossal Titan. Key moves include Atomic Ascension, Seismic Shock, Heat Wave, and Instant Volley. These moves, when maxed out, provide significant crowd control and damage potential.

Can I trade for the Colossal Serum?

Yes, if you are Prestige 3 or higher, you can trade for the Colossal Serum. This usually involves a 5,000 gem tax per trade. This is a viable path if you have the resources but lack the time to grind the raid.
