Status Effects indicate a state which is affecting the player. What kind of state can be seen in the lower right part of the screen. The icon's colour will reflect whether it is a buff or a debuff.
They generally do not have chevrons on the icon indicating the strength of the buff/debuff.
There are two exceptions to this: Template:IconLink and Template:IconLink.

Proficiency Indicators
The Proficiency System helps the player know how different gameplay elements (e.g. their own/other Players' Perks, Offering, Add-ons) affect their performance at the interaction they are currently performing by showing them Proficiency Indicators above the progress bar of the interaction.
The intensity levels are indicated by the number of chevrons on the icon. One chevron indicates the weakest form of an effect, and three chevrons indicate the strongest form. Those chevrons are accumulative with other gameplay elements affecting your performance.
The Icons will only appear when performing a specific action that is affected by a Status HUD. This currently applies to the following:

Perk Effects
The Perk Effects was the original system used prior to Patch 1.5.0 to display HUD information regarding Perks and Add-ons affecting Survivors and Killers. As of Patch 1.5.0, it's now only used for the Perks as effects applied by Add-ons are now displayed by the Status Effects and the Proficiency Indicators.
Unlike the newer system, it uses a light turquoise colour to display a buff. The colour is directly applied to the respective Perk's Icon, with a chevron additionally indication a buff/debuff.
