Perks

Perks are a type of power-ups in MultiVersus that grant various buffs to the Fighter they are attributed to. If the same Perk is selected by both players of the same guild, then that Perk will become Stacked.

Perks can come in one of the following categories: Offense (symbolized by the color red), Defense (symbolized by the color blue), and Utility (symbolized by the color green). There are also Fighter-specific Perks (titled "Signature Perks") that are symbolized by the color yellow.

Tips
While MultiVersus has not fully released yet, some Perks already found their place as the best in the game. Here are the best Regular Perks:
 * Triple Jump
 * Coffeezilla
 * Aerial Acrobat

These all provide either boost to movement or Cooldown reduction for abilities. Having more options for moving around the stage is always a huge bonus in platform fighters. As each Fighter has special abilities that may have Cooldowns, reducing this allows you to use your abilities more often.
