How Perks Work
Each perk has a value range. The value shown on a perk changes how strong the effect is. For example, a damage perk with a higher percentage gives a stronger damage bonus than the same perk with a lower percentage.
Not every perk can appear on every type of gear. Some are limited to weapons, some are limited to armor, some are available on pets, and some can appear on everything. Players should always compare the correct gear type because weapon, armor, and pet ranges can be different.

The best perk depends on the player's goal. For bossing, compare Boss Bane, Attack UP, Crit Stack, and Vampiric in the Best Bossing Perks guide.
For general ranking, use the Perk Tier List. It compares documented perks by practical usefulness across damage, farming, defense, mobility, sustain, and World 10 builds.
Unobtainable and Legacy Perk Ranges
Some perk ranges are listed as no longer obtainable. These older ranges may still matter when checking legacy gear, but they should not be treated as current farming targets unless the game changes again.
For old or removed perk information, use Unobtainable Gear Perks. For gear-specific legacy ranges, use Legacy Weapon Perk Ranges, Legacy Armor Perk Ranges, and Legacy Pet Perk Ranges.
Is It Worth Farming Perfect Perks?
Perfect perks can be worth chasing for players who want optimized builds, but they are not always necessary for casual progression. A strong near-perfect roll can still be useful, especially when the perk effect matches the build or activity.
For farming, focus first on getting the right perk type. After that, look for a higher value roll. Perfect rolls are best treated as long-term goals because some perfect perk drop rates are listed with very low chances.
