Item drops

Items that drop from monsters or item boxes follow certain drop rate calculations that determine which item or any item at all drops. Certain items, outside those obtained from monster or item boxes, equally follow calculations that determine the chance to obtain them. Examples include gambling items from Coren or redeeming Lucky Coins at the Lucky Roulette minigame. If chance is involved in obtaining items, the mechanism by which it will determine whether the item drops or not is commonly referred to as a "roll".

Item rolls

A roll can be synonymously viewed as rolling a dice, where you aim for a specific dice face to obtain the item. For example, if a monster drops an item with a 1/200 drop rate, it is synonymous to rolling a 200-sided dice where you will obtain the item only when 1 specific face out of 200 faces is rolled.

Monsters

Each time an enemy is defeated, the game rolls to determine whether an item will drop, and if so, what that item will be in the following order:

1. The game rolls for event drops, such as Event Egg, Halloween Cookie, or Present (Christmas)
2. The game rolls for Music disks (1/600 across all enemies)
3. The game rolls based on the enemy's Drop anything rate (DAR) to determine if the enemy has the possibility of dropping anything else
4. The game rolls to decide if the enemy will drop its specified rare item (depending on area, Section ID, and difficulty)
5. The game rolls to determine whether the drop is Meseta, a Tool, or the enemy's set drop (1/3 chance for any of these)

The chance to obtain items from enemies can be increased with drop rate boosts. DAR boosts increase the chance to obtain any item at all from monsters, which can also help with its designated rare drop. Rare drop rate (RDR) boosts only increase the chance for the designated rare drop. However, a monster can't have more than a 100% DAR. Certain monsters already have 100% (Bosses, rare enemies) or high DAR, where DAR boosts can't be utilized fully or only partially. A similar rule applies to RDR, in which the maximum RDR can only be boosted to 7/8 (87.50%). This however only applies to very few monsters (e.g. rare Rappies from VR Temple).

Item box

Each time an item box is opened, the game rolls to determine whether an item will drop, and if so, what that item will be in the following order:

1. The game rolls to decide if the box will drop its specified rare items (depending on area, Section ID, and difficulty). In many areas, item boxes have multiple rare drops assigned to them. The roll order is from top to bottom in the Drop charts
2. The game rolls to determine whether the drop is a Weapon, Frame, Barrier, Unit, Tool or Meseta (depending on area and difficulty; Yellowboze has a higher chance to obtain Meseta from item boxes).
