Shipping Request Form

The  is an item in Risk of Rain 2, added in the Survivors of the Void expansion.

When entering a new stage, if any player has this item, a Crashed Multishop "Delivery" will spawn somewhere in the stage (one per player who has a Shipping Request Form). The "delivery" is a burning Multishop Terminal which is different from a normal one in a few ways: it costs no gold to use, it has only 2 choices instead of the usual 3, and one of those 2 choices is a question mark icon (meaning the item of that rarity is unknown).

Math
The weight for each tier of item is calculated as follows:
 * for common
 * for uncommon
 * for legendary

Where  is the amount of Shipping Request Form.

To calculate the chance for a tier, add together all weights then divide that tier's weight by the total sum of all weights.

For example, if a player has 2 Shipping Request Form items, then the weights are 0.79 (common), 0.2 * 2 = 0.4 (uncommon), 0.01 * 2^2 = 0.04 (legendary). Then, the chance an item is legendary is 0.04 / (0.79 + 0.4 + 0.04) = 0.04 / 1.23, or approximately 0.0325, around 3%.

The table below shows the probabilities calculates for each value of. Note however that each delivery includes 2 choices. See the section below for odds of at least one legendary.

At least 1 Legendary
Each item tier is independent of each other, but each delivery drop contains 2 items. You can calculate the probability of getting at least one item from a tier by using the complement:, where   is the probability of getting at least one that tier (shown above).

For example, with a stack of 3, the chance of one item being chosen as legendary is 6% = 0.06. The chance that it is not legendary is, so the chance that both are not legendary is. The complement of this is the chance that at least one is legendary:, roughly 11.5%.

The table below shows the probability that at least one legendary item will appear a given stack of Shipping Request Form.

Tips

 * Having the allows the player to obtain both items from the delivery, instead of choosing one over another.
 * This is even more effective in multiplayer when multiple players have Shipping Request Forms; the player with the Executive Card can open each of the other players' deliveries for them.
 * Using the allows the player to find the Crashed Multishop "Delivery" faster, as it will be represented as two adjacent chest icons (InventoryIconOutlined.png) upon scan.
 * In multiplayer, all stacks of Shipping Request Form from every player will increase the item rarity of each Multishop spawned from this item. For example, if a player has 5 stacks of this item while another player has 1, both multishops that spawn from the two players holding it will have the item rarity of having 6 Shipping Request Form. So it is not advised for one person in multiplayer to horde all the Shipping Request Forms, as you lose out on more loot.

Trivia

 * This item has a very similar effect to the effect prior to the Anniversary Update.
