The Company: muster, the Coffer, writs and boons

How guilds work in The Ember Depths: weekly muster from every run, the five-chest Company Coffer, writs on the company board, Company Boons and Standing.

Every run you play musters points for your guild's week. On Monday (00:00 UTC, with the Rites) the Company Coffer opens at whatever tier the company reached, and every member who mustered claims a chest for each tier. Nothing decays and nobody is punished for a quiet week.

Muster

Each floor 2, dungeon 6, elite 1, boss 10, arena win 4, new Descent depth 4 — plus finished writs.
Up to 600 of yours count toward the Coffer each week; past that you still earn guild XP.
Full share: muster 150+ in a week and your claim gets one bonus roll (a rare item, or epic at the Crown Coffer).
A member adds at most 2,500 guild XP a week, and companies below level 5 earn ×2 guild XP.

The Company Coffer

Tier thresholds scale with the company's active members (at least 3), so a company of three and a company of thirty face the same effort per head. Gold is scaled to your hero level. Each tier reached also adds 1 seal to the treasury. You only claim tiers the company reached after you joined.

Chest	Muster per active member	Adds to your claim
Copper Coffer	40	1× gold · 3 Iron Scrap
Silver Coffer	100	1× gold · 2 Arcane Essence
Gilded Coffer	180	2× gold · 1 Void Crystal · a rare item
Ember Coffer	280	2× gold · 1 Forgotten Soul
Crown Coffer	400	3× gold · 1 Starshard · a epic item

Writs

Townsfolk post contracts on the company board. Hold up to 3; taking one takes it off the board for everyone, and it counts from the moment you take it. Unfinished writs vanish on Monday.

Company Boons

Officers spend seals to light a boon for the whole company until Monday. A company starts with 3 seals and gains 2 per guild level. Boons never apply in the arena.

Standing

Your lifetime muster across every company you've served: Hearthkin (0) → Delver (500) → Warden (2,500) → Lodge-Captain (8,000) → Ember-Sworn (20,000). It follows you if you move on, and shows on the roster.
