Skydrummer

A howlerbeast that grew up in the wilderness. This beast is indigenous to Talos-II. Strong membranes on its head and neck allow it to unleash powerful howling loud enough to shake...

Skydrummer is a Normal enemy of the Wildlife family in Arknights: Endfield. You will run into it in Transboundary Activation Point - Experimental Zone. Defeating it drops Howlerbeast Braid. Triggers when the boss drops to low HP. While enraged it performs charge-up attacks more often, deals more damage, and gains damage reduction — during this state apply Arts abnormalities (Shock, Freeze, Corrode, or Burn) or a physical Crash effect to strip its shield and reduce the danger; Crash is the faster route since it only needs one application.

How Skydrummer attacks — and how to dodge

Stagger HP: 320

Enraged State — Triggers when the boss drops to low HP. While enraged it performs charge-up attacks more often, deals more damage, and gains damage reduction — during this state apply Arts abnormalities (Shock, Freeze, Corrode, or Burn) or a physical Crash effect to strip its shield and reduce the danger; Crash is the faster route since it only needs one application.
Airflow Shield (Hard mode) — Outside of the enraged state, damage you deal generates airflow; when the boss enrages it absorbs all accumulated airflow and raises a shield whose strength scales with how much airflow was stored. Minimize damage output during the calm phase and prioritize dodging over sustained attacking to keep the eventual shield weak.
