Use the equations below and the one above as a system of equations to find out the rarity of each tier of items:Īll variables mean the same things as they mean in the first equation. For legendary items, you would use x 2/149, which would give you about 0.0604, meaning that 6.04% of items found would be legendary. This means that 40.27% of items also collected from rusty lockboxes would be uncommon. For uncommon tier items, it would be 20x/149, which would be approximately 0.4027 because you have 3 keys. Divide it out, and it is approximately equal to 0.5369, meaning that 53.69% of items collected from rusty lockboxes will be common tier.

The rarity of common items is 80/149, where 80 is the rarity value of common items and 149 is the net rarity. The equation has the net rarity of items equaling 149. For example, say you have x = 3 keys in your inventory. X = The number of keys in the team's inventoryĪ specific tier of rarity can be found by dividing its rarity value by the net rarity. This equation can be used to help you find the rarity of each tier of item:

The Rusted Keys multiply the chances of getting a Legendary tier item by the amount of keys the team has squared. The Rusted Keys multiply the chances of getting an Uncommon tier item by the amount of keys the team has. After choosing the rarity, it chooses an item at random from all available items from that tier. Then the chest, during its creation, uses this weight selection to select the rarity of the item.

To understand how the Key affects the chance on a specific rarity of item, one first needs to understand how a normal chest chooses an item: A normal chest has 80 chances for a common item, 20 for an uncommon item and finally 1 chance for a Legendary item. The key is not consumed upon opening a Rusty Lockbox, and losing the key using a 3D Printer will not prevent the Rusty Lockbox in that level from being opened. This item is unique in the fact that it doesn't modify the current stage and is quantified by all keys among the team rather than an individual. Whenever a new stage is entered, a Rusty Lockbox will spawn with the rarity of the contents based on how many Rusted Keys the entire party had when entering the stage. The Rusted Key is a new item in Risk of Rain 2. Special: Additional items increase the effect using a unique formula specific to the item
