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)

  • The additional armor is not affected by mods and is additive to total armor. For example, a ChromaIcon272.png Chroma with a max rank Mod TT 20px.png Steel Fiber, and active Rank 5 ArcaneGuardian64x.png Arcane Guardian will have an armor rating of:
    Base Armor × (1 + Armor Mods) + Arcane Guardian = 350 × (1 + 1.1) + 900 = 1,635 armor.
  • The Arcane Duration cannot be refreshed, while one instance is still active.
  • This Arcane cannot be activated while RevenantIcon272.png Revenant's MesmerSkin130xDark.png Mesmer Skin is active.
  • This Arcane cannot be activated when RhinoIcon272.png Rhino's IronSkin130xDark.png Iron Skin is hit.
    • However, the Arcane can be activated during 3 seconds of invulnerability after casting.
