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.

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.

Example

Say the player has 1× and 2×. This would result in:

* 1 * 3 = +% increased Critical Strike Chance

* 2 * 3 = +% increased Elemental Damage

If you equip all three Grand Spectrum of any type, you can use the following table, simply select the number of Grand Spectrum of the given type you intend to equip, and add the results:

Jewel limit

A character can't have more than three 'Grand Spectrum' jewels socketed. This limit is shared across all 'Grand Spectrum' jewels. For example, if a character has 3 Cobalt Grand Spectrum jewels socketed in their passive tree, they cannot use any Viridian or Crimson Grand Spectrum jewels.
