Head Banger

The second-window-specific spawn

Head Banger is unique among enemies because its spawn location is tied to a shop upgrade. Per the existing in-game documentation, the entity appears at the second check-in window — which means it can only spawn after you've purchased the Extra Check-In Window upgrade. Before that upgrade, the threat doesn't exist for you.

This is the one trade-off case in the shop catalogue: a permanent throughput upgrade that opens a new threat surface.

The Coffee (or food) counter

Per Destructoid's walkthrough, the counter is Coffee OR food — applying either to the entity ends the encounter. Coffee is the more accessible option because it's the universal sanity restorative (5 sanity per sip, 3 sips per cup — see /wiki/items/coffee) and you'll typically have one in inventory anyway. Food references the broader set of consumables; the specific food items aren't widely documented as Head Banger counters across community sources.

Why this enemy is "fair"

Most enemies require you to interrupt your current task to deal with them. Head Banger is anchored to the second check-in window — if you're already processing intake there, the response is essentially zero-overhead (apply Coffee, continue). It punishes ignoring the window entirely, not the workflow itself.

If you're running Secretary class for the per-check-in sanity passive, that passive doesn't directly counter Head Banger, but the increased time spent at the window means you're more likely to handle the encounter on contact.
