“Actually, we look at it as "surprise mechanics"”

Loot Box is an item obtained normally from The Mechanic.

Obtaining

Using The Mechanic, 2 Presents can be upgraded to 5 Loot Boxes. It takes 14 hours to upgrade and 70 Murphy Points will be earned.

Usage

Exchanges 10 of the same rare animal for loads of animals and items, as well as a special trophy.

— In-game description

Upon using Loot Box, a form will be prompted. By inputting the name of a rare animal, 10 of the that rare animal will be removed and exchanged for some common animals, rare animals and items. A Rare Animal Trophy corresponding to the rare animal exchanged will be obtained. If it is already obtained, more rewards will be given out.

The animals rewarded will be of the same type or the same leader's favourite animals as the corresponding common animal of the rare animal exchanged, but will not be the exact one. For example, if an Octopus is exchanged, the rewards can only be aquatic animals or Kraken's favourite animals, and neither Squid nor Octopus can be rewarded.

Detailed Formula

After using Loot Box, a counter will begin, starting from 0. There is a 5/9 chance the system rolls a common animal as a reward, a 2/9 chance it rolls a rare animal as a reward, and a 2/9 chance it rolls an item as a reward. The item rolls have the same weighting as rescues and quest rewards, without modifiers such as luck, quest modifiers or Rose.

A common animal reward will increase the counter by 1, a rare animal reward will increase the counter by 5, an item reward will increase the counter by 1 to 4, corresponding to the quality of the item. When the counter reaches 60 or more, no more rewards will be given out. This implies the counter can at most reach 64.

If the corresponding rare animal trophy has already been acquired, rewards will only stop when the counter reaches 75 or more. This implies the counter can at most reach 79.
