Phantom Captain Secret Unit Explained
Phantom Captain is classified as a Secret Unit, making it one of the rarest pulls in the game. Unlike standard mythic units, Secret Units usually have exclusive mechanics, higher value in late-game content, and strong long-term potential.
Phantom Captain is only obtainable during this limited-time event, meaning once the banner ends, there is no guarantee it will return anytime soon.
Captain’s Step Up Banner – How It Works
To get Phantom Captain, you must summon using the Captain’s Step Up Banner, which is only available for a limited time during Operation White Rose. Here is how the banner system works:
- The banner has 7 steps in total
- Every summon moves you forward by one step
- After reaching Step 7, the banner resets back to Step 1
- Each step requires a different gem cost
This system rewards players who commit to multiple pulls rather than single summons.
Best Steps to Get Phantom Captain
Not all steps have the same rates. Some steps are far more valuable if your goal is Phantom Captain.
Special boosted steps:
- Step 4 – 4x Mythic chance
- Step 5 – 2x Shiny chance
- Step 7 – 3x chance to summon the Secret Unit Phantom Captain
Step 7 is the most important step. If you are limited on gems, it is highly recommended to plan your summons so you can reach Step 7 at least once.
Summoning Tips to Save Gems
To improve your chances without overspending:
- Avoid stopping mid-way before Step 7
- Save gems until you can fully commit to multiple steps
- Focus summons during boosted steps only
- Do not waste gems on regular banners during this event
Because the banner resets after Step 7, players with enough gems can loop the banner multiple times for better odds.
Is Phantom Captain Worth Pulling?
Phantom Captain is designed as a high-value unit with strong late-game relevance. Since it is a Secret Unit tied to a limited banner, missing this event could mean waiting a long time for another chance. If you enjoy collecting rare units or want to future-proof your team, Phantom Captain is absolutely worth aiming for during Operation White Rose.
The Phantom Captain Secret Unit is one of the main reasons Operation White Rose stands out in Universal Tower Defense. With the Captain’s Step Up Banner offering boosted rates at key steps, players who plan their summons carefully can significantly improve their chances. If you have been saving gems, this is one of the best times to spend them. Make sure to take advantage of Step 7 before the event ends, as Phantom Captain may not return anytime soon.
