To get a 6 charm slot in Diablo 4, the usual answer from recent player reports is that it’s RNG-based : look for a seal with a +1 Charm Slot affix, or reroll/craft seals until one drops with that bonus.

How players are getting it

  • Random drop. Some players report finding 6-slot seals from regular play, campaign completion, or higher-tier farming.
  • Legendary seal with +1 charm slot. A common path is rolling or dropping a legendary seal that explicitly adds one extra slot.
  • Cube-style rerolling. Several reports say combining 3 seals in the cube can eventually produce a 6-slot version, though it sounds very luck-dependent.
  • Mythic seals. A few players say mythic-tier seals can also provide the extra slot, but they seem rarer.

Practical takeaway

If you want the fastest shot, farm seals and keep rerolling or combining until you see +1 Charm Slot on the item. The player consensus is that there is no guaranteed quest reward for it; it’s mostly chance and repeat attempts.

Small caveat

Some forum replies mention bugs or slot-display issues, so if you already have the right seal but the extra slot doesn’t appear, re-equipping, relogging, or restarting has helped some players.

TL;DR: hunt for a legendary or mythic seal with +1 Charm Slot , and if needed, keep rerolling/combining seals until one shows up.
