RPG Maker MV allows you to create up to three item drops for an enemy. When the battle is over, the player may receive up to any of these 3 items.
When you specify drops, you use something called a "denominator" probability, which is basically you specifying the chances of the item dropping as a fraction of 1.
For example, if an item had a 1/2 chance to drop, then it has a 50% chance to drop. If an item had a 1/3 chance to drop, then it has a 33.33% chance to drop.
Unfortunately, with this system, you could never have any probabilities in between.
This plugin addresses two issues:
You can specify more drops
You can specify probability using percentages
This should give you more flexibility when designing your enemies.
Want more freedom when it comes to enemy drops? Give this plugin a try!
