Partner Portal and Thieves Guild in The Bazaar (Patch 20.0)

Partner Portal lets you pick a second hero as a partner for the run: that hero’s items can then show up at merchants, and your Partner Skill makes them 50% cheaper. The Thieves Guild is a separate encounter you reach only by selling a Thieves Guild Medallion, which the Thug monster carries.

Partner Portal

Rule	Detail
When	Can spawn on Days 1 to 5 (Patch 20.0)
Tier	Diamond encounter
Choice	Choose a Partner hero for this run
Effect	That hero’s items can appear at merchants; Partner Skills give a 50% discount on them
Follow-up	Once chosen, a different Partner Portal can appear that upgrades an item from your partner hero

The portal started as the end-of-season event for Season 19 (Patch 19.4, 28 October) and joined normal rotation with Patch 20.0. Hotfix 20.1 fixed a rare case where the first version of the portal could still spawn after you had already chosen a partner.

Choosing a partner

Partner items keep their own tags, so a partner’s Burn, Shield or Haste items work with your skills that reference those effects. Hero-mechanic items need their mechanic: Heated and Chilled items need a source of the state, and Rage items need Karnok’s Rage skill, which Level Up can offer to any hero holding a Rage item.

Thieves Guild

Step	Detail
1	Beat the Thug (Diamond-tier monster, Day 7). The Medallion is in its loadout, replacing Bar of Gold since Patch 20.0.
2	Sell the Medallion.
3	The Thieves Guild is available at the start of the next day.

Mr. Moo runs the Guild. The Thug’s other loadout items are Double Whammy, Improvised Bludgeon, Pawn Shop and Toxic Brass Knuckles; a win gives one item from the loadout at random, so the Medallion is not guaranteed.
