Arcanes in Warframe are powerful components that fit in special Arcane slots on your Frames and weapons. When you first start playing you won't need to worry about them very much, but when you start to get further into the content, you will find that they can solve many problems you might be running into with your builds as the challenge level increases.
The best Warframe Arcanes
The bonuses from the Arcanes shown below assume the Arcane is fully ranked, meaning you need to find and combine 21 of the individual Arcanes. This means repeatedly farming the activity that they drop from, which you will also find listed below. It is possible to trade with other players for Arcanes, but this can be very pricey, depending on the set you are looking for.
