One of 14 primary arcanes on this site, and one of 14 at rare.

(In the planner)

The planner shows this arcane on a build but does not add it to the stats. Its effect only applies under a condition, so a stat sheet that added it in would be showing you a number the game gives you in one situation and not the rest. The same rule governs mods whose values have not been checked: a figure this site prints is a figure it can defend, and one it cannot defend is left out rather than guessed at.

Primary arcanes do not have a slot in the planner yet — Warframe builds are the ones with arcane slots today.

Where the same place appears under several reward tables it is listed once, at the best odds it offers — that is the figure a farm can actually achieve. A dash means the source is known but carries no published chance, which is usually a vendor rather than a drop.
