Quick checklists

Short, practical lists you can run through in under a minute.

After an update

  • Rejoin a fresh server (old servers can hide features).
  • Redeem newest codes first and confirm rewards.
  • Avoid blind summoning until you verify the current featured banner.

Before you summon

  • Set a Gems budget and stick to it.
  • Summon for roles you’re missing (DPS / CC / support).
  • Plan upgrades before spending everything on summons.

If you’re stuck

  • Leaking early: add early coverage or crowd control.
  • Timing out late: add scaling DPS or boss damage.
  • Use calculators to choose the cheapest upgrade breakpoint.
