What's on the Hero Siege market
On October 26, 2026, Steam's Market search returned 134 Hero Siege items, the same number our catalog has recorded. Every item in a sample of the most popular Hero Siege listings was flagged by Steam as a commodity. Steam's Market FAQ describes commodities as items where "all the items are identical, and can be traded interchangeably". Every "Companion | Alice" is the same as every other one, which is why they can go on Steam's Multisell page together.
How Hero Siege item names work
124 of the 134 names start with a type, then a vertical bar, then the item's name, for example Hat | Helm of Fafnir. Here's how our catalog breaks down by that type:
| Type | Items | Examples (exact Market names) |
|---|---|---|
| Companion | 21 | Companion | Alice, Companion | Dodo |
| Hat | 13 | Hat | Helm of Fafnir, Hat | Holy Warrior's Helmet |
| Shield | 11 | Shield | Dragon Targe |
| Mace | 9 | Mace | Mjolnir |
| Sword | 9 | Sword | Swordpan |
| Emote | 7 | Emote | Viking Rage |
| Skin | 7 | Skin | Werewolf |
| Axe, Polearm | 5 each | Axe | Ragnarok, Polearm | Ice Lance |
| Dagger, Gun, Staff, Wand | 4 each | Gun | The Beast, Staff | Staff of Origins, Wand | Arcane Coil |
| Bow, Spellblade | 3 each | Bow | Deathstalker's Bow |
| Back Accessory, Cane, Chainsaw, Claw, Flask, Spellbook, Throwing | 2 each | Back Accessory | Ritual Backbag, Claw | Freddy Kruegers Blades, Flask | Timebomb |
| Wings | 1 | Wings | Wings of the Seraphim |
Chests and keys
The other 10 names have no type prefix. Seven are seasonal or themed chests: Christmas Chest, Halloween Chest, Angelic Chest, Steampunk Chest, Hellfire Chest, Northern Chest and Cultist Chest. Two are key items, Satanic Key and Key Fragment, and the last is Troll. Chests and keys are often the items people have the most duplicates of, so they're a good place to start a bulk listing.
The Hero Siege Multisell page lists the full catalog, with a link to each item's Steam Market page for current prices and buy orders.
What you keep from a sale
The Market FAQ lists a separate game fee only for Counter-Strike 2, Team Fortress 2, Dota 2 and Artifact. For Hero Siege, only the 5% Steam Transaction Fee applies, with a minimum of $0.01. It's added on top of your price, so you keep about 95% of what the buyer pays. On very cheap items the $0.01 minimum takes a bigger share. On a $0.05 item, for example, the $0.01 fee is a fifth of the price.
Proceeds go to your Steam Wallet, which caps at $2000. They can't be withdrawn to a bank (Market FAQ).
How to sell Hero Siege items in bulk
- Check your account can sell. You need a purchase more than 7 days old (but not older than a year) and Steam Guard on for 15 days (requirements).
- Make your inventory public (how).
- Open the Hero Siege builder, paste your Steam profile URL, custom URL name or SteamID64, and click Load inventory.
- Pick items and quantities. Duplicate chests and companions show as one row with a count.
- Open the Multisell link while signed in to Steam, set prices, submit, and confirm in the Steam Mobile App if you use the authenticator.
Listings created before you've had the Steam Guard Mobile Authenticator for 7 days can be held for up to 15 days (Mobile Authenticator FAQ). Items bought in-game or on the Market can't be sold until the date shown on the item (Restrictions FAQ). If something won't list, see why you can't sell on the Steam Market.
Pricing tips
- Price by exact name. Each item, such as "Companion | Alice", has its own Market page. Similar-sounding items aren't interchangeable.
- Check buy orders for chests. The Market FAQ says buy orders show "what other users are willing to pay for an item", so you can "do a lower price to sell immediately; or go for a higher price and wait".
- Value the inventory first. Our Steam inventory value guide shows how to total up after fees.
Hero Siege trading cards
Hero Siege also has Steam Trading Cards, according to the Steam Store. Cards go into your Steam inventory, not the Hero Siege one, so they won't show in this builder. See how to sell Steam trading cards for selling, badges and gems.
Load your inventory in the Hero Siege Multisell builder and list your companions, chests and cosmetics in one batch.
