When does the Arknights Monster Hunter collab start?

Global: November 16, 08:00 through November 30, 03:59 (UTC-7) for the side story Thunder in the Azure Dream and the limited headhunt. Unlock: clear Main Story 1-10.

What is on Hunters of the Umbral Wilds?

Rate-up Limited: Violet Mizutsune Orchid (6★) and Zinogre S Catapult (5★). Phantasmal Pursuit Headhunting — they are not in Standard or Kernel. Violet Mizutsune Orchid is guaranteed every 120 pulls; the count resets when you obtain her.

Is there a free operator?

Yes. Rhodes Island Recon (1★ Vanguard) comes from Thunder in the Azure Dream event missions (Mandate of the General). Not from the limited headhunt.

What are the free 10-pulls?

Hunting Time login (Nov 16–30): days 1 and 8 each give a Song of the Bow, Leap to the Sky Headhunting Permit — a 10-pull locked to this collab banner that expires November 30, 03:59 (UTC-7).
