A Universal Time Update 6.4 Codes

I found two codes, but no source lists their rewards yet, so treat them as unverified.

How to Complete Willow’s Halloween Quest?

  1. Talk to Willow at the Witch’s Hut.
  2. Go to Hollow’s Garden, finish Hollow’s quest and talk to him again.
  3. Return to Willow. She asks for three materials.
  4. Complete Ignis’s quest for the Hollowed Frame.
  5. Complete A Certain Pumpkin’s quest for the Luminous Soul.
  6. Complete Kodama’s quest (near the Witch’s Hut) for the Spectral Solvent.
  7. Give Willow all three to receive the Hollowed Lantern.
  8. Defeat Grim, then return to Willow.

Tip I’d flag: Kodama needs you to craft Green Senbei. Crafting it before the right quest step won’t count, so accept and progress the quest first.

Finishing the quest also gives you a badge and the “Complete Willow’s Quest” title.

Accursed Lantern Subpower

Use the Hollowed Lantern on the Sinkhole gates to open the path to Grim’s Arena. You can repeat Willow’s lantern quest to put the Subpower on multiple abilities. Revenant is only vulnerable after you hit it with the Accursed Lantern, so get this first. Our Sinkhole and Grim guide goes deeper.

Boss Rewards: Grim and Hollow

BossEvent CurrencyOther Drops
Grim500 (top), 400 (2nd-3rd), 300 (4th-5th)Random skin 85% (top 3), Grim’s Scythe 15%, Inhumane Spirit 20%, Veilshard Fragment 100% (top attacker only)
Hollow250 (top), 200 (2nd-3rd), 150 (4th-5th)Random kill effect 85% (top 3), Hollow’s Scythe 15%, Pumpkin 30%, Cursed Apple 20%

To summon Hollow, unlock the Event Ladder, talk to Hollow again and spend one Veilshard Fragment. Only the top Grim attacker gets that fragment, so push your damage. Grim also earns the “Defeat Grim” title.

Event Ladder and Unusual Reroller

Deposit uE in the Event Ladder to claim rewards. Completing a stage lets you refresh it. uFragments appear at stages 3, 5, 7 and 10. The official description promises 20+ free cosmetics from the ladder.

The Halloween Unusual Reroller rerolls patterns on the new skins for uE. Halloween Crates also return, with old and new prizes. Four new charms appear on unusuals: Blood Moon (21), Pumpkins (22), Horns (23) and Hex (24). Spend uE carefully, because the ladder, crates and reroller all use it.
