Why can I not change my pick?

Because a call you can revise is not a call. Locking it is what makes the credential mean anything.

Does entering cost anything?

No. The pick is free; only the waiting costs you.

What is the credential?

An epic-tier badge on your profile for that week's boss. It is cosmetic, and that is the point.

Weekly Boss

One free pick. One real event. One week of waiting.

The Weekly Boss is a single hard call on an event that resolves in the real world, on its own schedule. One free pick per player, no edits, and then a week of finding out. Beat it and you collect a fixed PP prize and an epic credential on your profile — worth having precisely because most of the people who tried got it wrong.

How it works

Read the week's boss market and lock in one pick.
Wait. The event resolves for real, when it resolves.
Beat the boss and take the fixed PP prize plus an epic credential.

The rules that matter

One free pick per player, and it cannot be changed.
A voided event is a clean slate: no hit, no miss, no reward.
