World Level

World Level affects the strength of some enemies from Breath of the Wild.

Whenever Link kills an enemy, a hidden counter goes up a certain number. When the counter reaches a specific number, the World Level will be increased, and some enemies and weapons will be upgraded by one tier - for example, many Blue Bokoblins would be replaced by Black Bokoblins.
