Grand Spectrum

Grand Spectrum is the name shared by three different unique jewels that each grant scaling bonuses based on the number of jewels called 'Grand Spectrum' placed into jewel sockets on the character's passive skill tree. The jewel limit is shared across all three types of Grand Spectrum. For example if you have 3 Cobalt Grand Spectrums socketed in your passive tree you cannot use any Viridian or Crimson Grand Spectrums.

Mechanics

The total magnitude $\color[RGB]{163,141,109} M_t$ of the bonuses granted by socketed Grand Spectrum jewels of type $\color[RGB]{163,141,109} t$ is

$$\color[RGB]{163,141,109} M_t = b_t \times n_t \times g$$

where $\color[RGB]{163,141,109} \text{b}_t$ is the nominal magnitude of the bonuses granted by Grand Spectrum jewels of that type, $\color[RGB]{163,141,109} \text{n}_t$ is the number of socketed Grand Spectrum jewels of that type, and $\color[RGB]{163,141,109} g$ is the total number of socketed Grand Spectrum jewels.
