In a game patch, the developers change a character. They increase damage, reduce cooldown, or add health. That is a buff. The opposite is a nerf. Buffs make a character stronger. They are usually welcome. Players celebrate. But buffs can also break the game. A buffed weapon can dominate. A buffed hero can become a must-pick. Then the developers have to nerf it later.

The word has a physical origin. A buff person is muscular. To buff something is to strengthen it. The gaming use came from MMOs like EverQuest and World of Warcraft. A buff was a temporary spell that made you stronger. Now it applies to any balance change. "The new patch buffed tanks." "They buffed my main, I'm so happy."

Types of buffs

• Stat buff: increase health, damage, or speed.
• Utility buff: improve a skill or item.
• Indirect buff: nerfing a counter makes a character stronger.
• Quality of life buff: makes a character easier to play, not stronger.

Buffs are a conversation between developers and players. Players complain. Developers adjust. The cycle never ends. A buff is a gift. It is also a test. If it is too strong, it becomes a problem. If it is too weak, it is ignored. The perfect buff is invisible. It makes the game better without anyone noticing.
