All drop rates data is obtained from DE's official drop tables. See Mission Rewards#Standard Missions for definitions on reward table rotations. Drop chances are rounded to two decimal places, following the official drop tables repository.
Expected means a player can expect to obtain at least one of a drop every N attempts on average.
Nearly Guaranteed refers to the total number of attempts a player needs to obtain a 1 in 10^2,3, and 4 probability not to have recieved a single drop (99%, 99.9%, and 99.99% probability to have received at least one drop).
The combined probability of multiple drops is 1 - ((1-A%) * (1-B%) * ...) (add drops in same rotation)

  • This Arcane was originally dropped in The Jordas Verdict. Following Update 22.14 (2018-03-01), all Trial missions were retired from the game and the Arcane drops, in turn, were moved to the Eidolons instead.
  • Prior to Update 24.2 (2018-12-18), Arcane Arachne damage multiplier could be stacked upon subsequent wall latches, allowing for a large damage increase on the next hit.

Patch History[]

Update 31.6 (2022-06-09)


We’ve adjusted the values of older Arcanes with the goal of making lower rank Arcanes more viable, and more desirable while collecting as a result. In short, there are three stats that each Arcane tends to have (speaking generally) -- for example, a percentage chance, a stat buff, and the duration of the buff.

Certain Arcanes increase all of these stats per rank (making them scale exponentially), but we are changing it so that only one stat is affected by rank (making it scale linearly). The other stats will now be at the max-rank value regardless of the Arcane Rank, thereby buffing lower-rank Arcanes as a result.
