To maintain smooth performance and protect your account resources in DRAGON BALL Z DOKKAN BATTLE, clear your app cache from the title screen menu when visual issues occur and save your Dragon Stones for high-value anniversary or major campaign banners.

Technical Maintenance and Asset Management

Major patches introduce large asset updates that can cause performance issues or verification errors on local files. Execute these steps to keep the game running reliably:

  1. Clear the Game Cache: If character animations stutter or display graphical glitches, open the game to the main title screen, select the menu option, and clear the cache before attempting a fresh download.
  2. Download Large Assets over Wi-Fi: Perform full data downloads only while connected to a stable Wi-Fi network to avoid corruption during high-resolution animation updates.
  3. Monitor Maintenance Windows: Check the in-game news feed for announced maintenance schedules. Server-side maintenance typically begins several hours before new banners or major updates go live.

Summon Strategy and Unit Evaluation

Managing your Dragon Stones efficiently requires evaluating a unit's long-term utility rather than spending currency on every new release.

Evaluating Defensive vs. Offensive Stat Passives

Units with defensive utility hold their value longer as new events introduce tougher boss encounters. When deciding whether to spend Dragon Stones, compare the character's kit against these design archetypes:

Kit FocusKey Passive MechanicsMeta DurabilityRecommendation
Defensive UtilityDamage reduction, stat stacking, defensive buffsHighPriority investment for long-term content
Pure OffensiveHigh turn-one attack stats, minimal defenseLowHigh risk of falling off during power creep shifts

Resource Hoarding Strategy

  • Save for Major Celebrations: Prioritize spending Dragon Stones on anniversary banners and major global campaigns. These banners feature top-tier units that define the baseline requirements for future challenging events.
  • Skip Regular Banners: Avoid spending sporadically on standard releases between major events, as non-campaign units carry higher risks of quick obsolescence.
