FAQ & Guide

How to get verified and where to find every tool and feature.

Getting started & verificationBuying, selling & auctionsTools, calculators & timersReputation, vouches & trustPolygon Passport & progressionGoblin's Forge

Getting started & verification

How do I verify and unlock the community?

In Discord, open the #how-to-verify channel and press the Verify button. Your Discord account must be a few days old (this blocks throwaway alts). Then go to #roles and choose your realm(s) and language — that unlocks the trade channels and filters pings to what you care about.

How do I link my in-game character?

Use /link in Discord, or open your profile here on the site. Linking proves ownership (via a quick market listing under your character name, or a moderator) and lets you sell on that realm and earn a Verified badge.

Buying, selling & auctions

How do I sell or buy?

Post a listing on the site or in Discord with /sell (selling, WTS) and /buy (wanted, WTB). Item listings support Excellent options and Ancient sets. Toggle your availability with /online.

Sell →Buy →Browse listings →

How do auctions work?

Use /auction for a timed auction — the highest bid when the timer ends wins. Bids are placed in Discord. There is an anti-snipe extension on last-second bids.

How do I find things or get notified?

Use /search to search active listings, and /watch to get a DM when a matching listing is posted. Reference prices live on the Market Index and Trending pages.

Market Index →Trending →

Big deal — how do I stay safe?

For large trades open a Guarantor (escrow) ticket with /mm. Pay untrusted sellers only after the service. Check anyone with /blacklist info, and report scams with /report.

Tools, calculators & timers

What calculators are there?

Stat Calculator (damage/DPS/optimizer), Enhancement cost (+12…+15), Elemental Resist, the Chaos Machine odds simulator, Set Bonus and a fair-price appraisal (/appraise in Discord).

Where is the item info and Ancient sets?

The Item Library has every item with stats, requirements, options and live listings. Ancient Sets lists all 63 sets and their bonuses. In Discord: /item, /ancient, /drop and /farm.

Item Library →Ancient Sets →

Where is the Chaos Breach timer?

In Discord use /breach — it shows the Chaos Breach timer and lets you form parties with shared timers. Boss respawns are on /spawn and the event schedule on /events.

Live server data?

Server status, rankings, Castle Siege and per-realm stats are on the site and in Discord (/status, /rankings, /siege, /char, /server).

Status →Rankings →Castle Siege →Servers →

Market prices & alerts?

The Market Index tracks median prices twice a day. Use /price for a live price, /pricealert to get a DM when a price crosses a threshold, and /rate for community exchange rates.

Reputation, vouches & trust

Vouches vs reputation?

A vouch confirms a completed service (/vouch @user <service>) — not an item trade. Reputation (/rep @user) thanks helpful members for advice, pricing and builds. Check anyone with /card.

How do service-provider ranks work?

Unique service vouches automatically grant provider ranks — the live ladder is posted in #rep-ladder. Do the service, get vouched, climb the ladder.

Polygon Passport & progression

What is the Polygon Passport?

Your level, XP and badges across everything you do — trading, vouches, arena, the enchant mini-game, sieges, giveaways and tenure. Use /passport to see your card and /passport badges for the full badge catalogue and how to earn each one. Your level and badges also show on your profile.

Your profile →Goblin's Forge mini-game →Tournaments →

My level looks stuck — why?

XP is computed from recorded activity and refreshes automatically after sales, auctions and vouches, and on a daily pass. Open /passport to force a refresh. Each source is capped so no single activity dominates. If it still looks wrong, ask a moderator to recompute it.

Goblin's Forge

What is Goblin's Forge?

A Ranked mini-game on the site (and /enchant in Discord): craft Wings of Satan, enchant them toward +15 with jewels, shop for talismans and protection at the Goblin, bank Ascended trophies, and climb the season ladder. Failures can shatter wings; Phoenix Feather can revive your last pair.

Open Goblin's Forge →Ranked ladder →

Where do I earn currencies (jewels / feathers / flames / essence / arcane)?

Jewels (◈) come from the daily allowance and arcade games (Cache, Boss, Gemfall, Wheel, Rune). Feathers (🪶), Flames (🔥) and Arcane (💠) drop from arcade jackpots and events. Wing Essence (✶) is earned from enchant milestones, deep-shatter salvage, Commission claims, Gambit wins, and the Refinery (convert feathers/flames → essence, capped per UTC day).

Wallet →Arcade / Arena →

What can I spend each currency on?

◈ Jewels — craft wings and enchant rolls (or spend free Daily Sparks). 🪶 Feathers — Forge gear (talismans, Diligence, reroll), Refinery. 🔥 Flames — protection (Chaos Assembly / Ward), Goblin’s Gambit stake. ✶ Essence — Harmony, Coin of Fate, Guardian, Phoenix, upgrade, some Forge prestige. 💠 Arcane — Ascend, engraving, high-end auras/dyes.

How does enchanting (точка) work?

Create Safe or Risky wings, then apply Bless / Soul / Life / Chaos jewels on The Anvil toward +15. Luck and excellent options matter for power and score. Three shatters on a tier demote you; Phoenix restores the last destroyed wing. At +15 you can Upgrade (tiers I–IV) or Ascend (tiers III–V) into your Wing Collection.

What are Daily Contracts and Goblin’s Commission?

Daily Wing Contracts — three UTC-day goals (e.g. reach +11, land Double Damage). Claim Essence/Feathers when done; one Feather can reroll a goal. Goblin’s Commission — three weekly goals mixing Forge spends, contracts, +12 pushes and arcade actions. Ranked only. Claim rewards to your wallet when progress fills.

What is Forge 2.0 (Sparks, Heat, Molten, Gambit, War)?

Daily Sparks — free enchant clicks that reset each UTC day. Forge Heat builds on manual rolls; at 100% you get a short Molten window (+odds or −cost). Goblin’s Gambit stakes 1🔥 on the next soul/chaos roll for Essence + double Commission progress. Forge War is a weekly realm race; Duels of Smiths are timed 1v1 climbs. Live Feed shows other smiths’ big moments.

What rewards should I chase?

Wallet payouts from Contracts / Commission, Ascended wings for prestige and avatars, season ladder rank, War / Duel glory, dyes & Sigil auras for cosmetics, and achievement feats (including Molten and Mastery hunts).
