BrownDust2 Diamond Top Up Guide 2026: How to Recharge on Kardz

BrownDust2’s 3rd anniversary event runs from June 4 to the end of August, giving out more than 1,300 free pull opportunities over 12 weeks. With limited costumes arriving one after another, Diamonds are being spent much faster than usual.

The current July banner is the Beach Angel Teresse rerun. The community recommends pulling her to at least +3 or +5. This character is widely regarded as one of the strongest supports in the game, with dual buffs that increase both ATK and MATK. She is also limited, so if you miss her this time, no one knows when the next rerun will come.

If you are short on Diamonds, this guide explains how to top up on Kardz and the difference between the two recharge methods.

Kardz Has Two Top-Up Methods, So Confirm Which One You Need First

BrownDust2 supports two different methods on Kardz at the same time. This is different from most games, so make sure you understand the difference before placing an order.

Self Top-Up
You log in to your own game account and complete the top-up yourself. You do not need to give your account password to customer support. The process is faster and more secure, making it suitable for players who can log in directly with a Google account. This is the recommended option.

Login Top-up
You provide your account and password to Kardz customer support, and the support team completes the top-up for you. This is suitable if you run into issues with Self Top-Up or if direct top-up is unavailable in your region. Remember to change your password immediately after the Login Top-up is completed.

After entering the Kardz BrownDust2 top-up page, you will see these two options at the top of the page. Choose one first, then scroll down to select the Diamond package.

Self Top-Up Steps

Step 1: Choose the top-up type and package

Go to the Kardz BrownDust2 page, click “Self Top-Up,” then select the Diamond package you need. The page includes monthly passes, sprint packs, regular Diamonds, 3rd anniversary exclusive packs, and more. Choose based on your current needs.

Step 2: Complete payment

Visa, MasterCard, PayPal, and local payment methods in different regions are supported. After selecting your payment method, pay directly.

Step 3: Log in to your game account to complete the top-up

Kardz will guide you to log in with your own Google account and confirm the transaction. The whole process is completed on your own device. Diamonds are delivered directly to your account, with no need to wait for customer support.

Login Top-up Steps

Step 1: Choose the Login Top-up method and package

Select “Login Top-up,” choose the package, then submit your order and complete payment.

Step 2: Provide account information

After payment, provide the following information to Kardz customer support:

• Google account email

• Account password

• Character ID

Step 3: Wait for completion

Do not log in to the game during the top-up process, and keep the account logged out. Customer support usually completes the operation within 15 minutes and will notify you once it is done. After receiving the notification, enter the game and confirm that the Diamonds have arrived.

Step 4: Change your password immediately

The first thing to do after a Login Top-up is completed is to change your password. Once you have shared account information with a third party, changing the password promptly is the most direct way to protect your account. Do not delay it.

Google Account Notes

Whether you use Self Top-Up or Login Top-up, your Google account may require backup verification codes during the process.

If you run into verification code issues, contact Kardz customer support in time and cooperate with them to avoid delayed delivery due to expired codes.

If you need a top-up receipt for reimbursement or records, contact customer support and add a note before submitting the order. It may be too late to request it after placing the order.

How to Plan Diamonds During the 3rd Anniversary Without Wasting Them

The 3rd anniversary event lasts until the end of August, the Teresse rerun runs until the end of July, and more banners are coming afterward.

A few suggestions:

Check your pity distance before topping up. BrownDust2 pity does not carry across banners. Each banner is calculated independently, so confirm whether your current pity still applies before moving to the next banner.

Pay attention to the difference between Paid Dia and Free Dia. Some limited banners only count Paid Dia spending toward Spark, the guaranteed exchange system. Pulls made with free Diamonds may not count. Confirm the rules of the current banner before topping up.

The Teresse +3 vs +5 question. The community currently recommends at least +3. +5 is only worth chasing as a deep investment for players who have MC.Teresse. If you do not have MC.Teresse, get her to +3 first and wait for the next rerun to finish upgrades.
