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 amount of health restored refers to health per second, not the total of the duration.
  • Does not trigger on RhinoIcon272.png Rhino's IronSkin130xDark.png Iron Skin taking damage.
  • Low framerates can lead to irregular health regen properties.
  • Works best on warframes with high base Health and Armor, such as NidusIcon272.png Nidus, GrendelIcon272.png Grendel and InarosIcon272.png Inaros.
