Modifiers

Gain 30 Mana per Grand Spectrum: Grand Spectrum grants additional maximum mana based on how many jewels called 'Grand Spectrum' are placed into jewel sockets on the character's passive skill tree. Any 'Grand Spectrum' jewels are counted when determining the bonus, not only those with the Cobalt Jewel base type.

Jewel limit is shared among all other versions of Grand Spectrum.

Effect calculation

The total magnitude $\pagecolor[RGB]{15,15,15} \color[RGB]{163,141,109} M_t$ of the bonuses granted by socketed Grand Spectrum jewels of type $\pagecolor[RGB]{15,15,15} \color[RGB]{163,141,109} t$ is

$$\pagecolor[RGB]{15,15,15} \color[RGB]{163,141,109} M_t = b_t \times n_t \times g$$ where $\pagecolor[RGB]{15,15,15} \color[RGB]{163,141,109} \text{b}_t$ is the nominal magnitude of the bonuses granted by Grand Spectrum jewels of that type, $\pagecolor[RGB]{15,15,15} \color[RGB]{163,141,109} \text{n}_t$ is the number of socketed Grand Spectrum jewels of that type, and $\pagecolor[RGB]{15,15,15} \color[RGB]{163,141,109} g$ is the total number of socketed Grand Spectrum jewels.
