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)

Average Damage Multiplier per second only applies to single target DPS calculations. Note that hits marked as "Slam Attacks" will not apply at the epicenter of a single target hit so these will not be accounted for in avg dmg multi/s calculations. Combo animation lengths are approximate and are only accurate within a few tenths of a second.

Trivia

• The name of the weapon may have come from the English word "Arum", and Italian word "Spinoso".
  • The arum is a flowering plant seen in Europe, northern Africa, and western and central Asia.
  • "Spinoso", in Italian, means "Prickly", or "Thorny".
