"A delivery containing 2 items will appear in a random location on each stage. Increases rarity chances per stack. Corrupts all Rusted Keys." Every stage you enter, a free Crashed Multishop spawns with 2 item choices - no gold required. Legendary chance scales exponentially with stacks. Works even with Artifact of Sacrifice. Corrupts all Rusted Keys on pickup.
When Sacrifice removes all chests from stages, Shipping Request Form deliveries still spawn. This makes it one of the only sources of item choice in Sacrifice runs.Legendary weight scales exponentially with stacks (0.01 x n²) while uncommon scales linearly (0.20 x n). In multiplayer, stacks from all players combine for rarity weighting.
In multiplayer all players' stacks combine for rarity weighting. If one player has 5 stacks and another has 1, BOTH deliveries use the rarity weight of 6 stacks. It is almost always better to spread Shipping Request Forms across multiple players - more free deliveries AND shared rarity boost.
Executive Card lets you take both items. Normally you pick one of the two delivery choices. With Executive Card you take both - effectively doubling the value of every delivery. In multiplayer one player with an Executive Card can open all teammates' deliveries and claim both items from each.
57 Leaf Clover boosts the hidden rarity roll. The question mark slot's rarity is rolled randomly. Clover's luck bonus improves all random rolls including this one, pushing the unknown slot toward higher rarities. Artifact of Sacrifice removes chests - but not deliveries. In a Sacrifice run, Shipping Request Form deliveries are one of the few remaining sources of guaranteed free item choice. Stack multiple for consistent quality loot when enemies are your only other option.Shipping Request Form is a void uncommon item that spawns a free Crashed Multishop "Delivery" on every stage you enter. The delivery is a burning terminal with 2 item choices (one is a visible rarity, one is a question mark), costs no gold to use, and never offers equipment. Stacking increases the chance of getting higher-rarity items from the delivery. It corrupts all Rusted Keys on pickup.
Yes. Each additional stack increases the weight toward uncommon and legendary items in the delivery. Uncommon weight scales linearly (0.2 x stacks), legendary weight scales exponentially (0.01 x stacks squared). In multiplayer all player stacks combine - so spreading the item across multiple players gives more free deliveries AND better rarity odds.
Generally yes. Shipping Request Form gives a free 2-item choice terminal every stage (effectively 2 free items to choose from with no gold cost), while Rusted Key gives one item per stage from a hidden cache but is consumed on use (requiring a new key each stage). Shipping Request Form also scales better and works with the Artifact of Sacrifice. The main downside is corrupting your Rusted Keys.
At 1 stack the chance of one item slot being legendary is roughly 1%, matching a small chest. With 5 stacks it reaches about 12% per slot (around 22% chance of at least one legendary across the 2 choices). At 10 stacks it reaches about 28% per slot with nearly a 50% chance of seeing at least one legendary in the delivery.
Yes. The Crashed Multishop spawns even when the Artifact of Sacrifice is active, making it one of the only sources of item selection when Sacrifice removes all chests. This makes it particularly valuable in Sacrifice runs where loot options are otherwise entirely random drops from enemies.
The Executive Card equipment lets you take both items from a multishop terminal without closing the other option. With Shipping Request Form deliveries, this means you can grab both choices instead of one. In multiplayer, a single player with an Executive Card can open all teammates' deliveries for free, claiming both items from each.
