WARFRAME Wiki:Glossary

• Purging a page's cache on the server through ?action=purge: Wikipedia:Purge#Purge request to server.
• When talking about client-side (JavaScript) scripts, it may also refer to purging the local browser's cache: Wikipedia:Purge#Purge_local_browser_cache

• See https://warframe.fandom.com/wikia.php?controller=DiscussionPost&method=help&format=json for documentation. For example, to get discussion posts: https://warframe.fandom.com/wikia.php?controller=DiscussionPost&method=getPosts

• Describes how efficient a weapon is in using its ammo to kill enemies. High ammo efficient weapons are able to use less ammo to kill the same amount of enemies compared to a low ammo efficient weapon.
• Another measurement of ammo efficiency is how long a weapon is able to sustain its usage when killing enemies. Since enemies have a chance to drop different types of ammo pickups (each giving different amounts of ammo), an ammo efficient weapon should be able to be used for a long time since there is a net gain in ammo while killing enemies. Ammo inefficient weapons will typically experience a net loss in ammo when killing enemies since they don't do enough damage per shot.
• Not to be confused with the "Ammo Efficiency" stat provided by some mods like  Zazvat-Kar or Arcanes like  Void Fuel.

• affect movement: slows (like  Cold procs), stuns, freeze (like  Avalanche),  Lifted, Blinds, Knockbacks
• affect ability/weapon usage:  Silence, Disarms, interrupts
• force an action: taunts (i.e. increase Threat Level),  Mind Control, fear (like  Terrify), charm (like  Lantern)

• A standard way of measuring theoretical damage output within a set period of time. There are many ways of calculating DPS depending on the period of time (burst DPS for instantaneous point in time or sustained DPS for over an extended period of time).
• May also refer to a player role that is primarily the damage outputer of a squad. Examples include  Mesa and  Saryn.

For example, say a player wants some new weapon, so they need play missions to obtain the blueprints and resources necessary to create that weapon. Then they need to level up their weapon so it can be more powerful. Once the player faces content that is difficult to the point said new weapon is not sufficient, they will need to find a new weapon to invest in.

Opportunity cost can be extended to equipping weapons in certain slots. For example, there is an opportunity cost in equipping a weaker primary weapon like the  Braton over a powerful one like the  Kuva Bramma.

• The weapon defeats an enemy in as few shots as possible (high damage per shot and ammo efficient)
• Or is able to deal lots of damage in the shortest amount of time (high DPS).
