Inventory vocabulary for Concordia / Section 0 — tools, keys, scrap, currency, and identity items you carry in Pack while playing on arco.host.
Wrench is the harvest / dismantle channel. In public watched rooms, facility security may interrupt harvest with a laser — see Systems · Harvest / security. Your own apartments stay safe for harvest.
Skeleton key opens certain locked public or keyed doors. Apartment keys bind to owned units and follow the property code under Residences / Real Estate.
Copper is the base unit for small asks and fees. Silver equals 100 copper and covers apartment buys and larger asks. Listings that opt in appear on the website Real Estate board — never an automatic dump of every unit.
Stackable scrap from dismantle lives in Pack bag slots. Catalog furniture and ceiling fixtures are placeables in Design / World Builder, not Pack tools — see Building parts.
A micro-avatar is a tiny front-walker portrait captured from your active character; successful uploads show on Account and your public profile. Profile photo is the larger Directory orb image — separate from the micro-avatar. Details under Systems · Micro-avatar.
Hit points are segmented (max 100). A security laser harvest zap drains 10% of max HP; at 0 HP you take a soft stun until you recover. Stamina and magic are not in the live HUD yet — see Systems · Mood & health.
