"Command +X" is bugged. It should add +X Insightful bonus to all CHA skills, but instead of adding the stated X value, it actually adds a higher value (this value, let's call it Y, corresponds to the "Insightful Alluring Skills" bonus of that level, which is the same as the Cannith Crafting Insightful Skill value for said level). This still correctly counts as an Insightful bonus. This affects named items, randomgen items (namely "Celebrated" ones), and the new Brightbane Emeralds (both varieties).

Regarding the diamond only, for some reason many effects are often +/-1 compared to what's advertised, due to some weird fractions (where on earth do they come from?) that don't make sense.
If you look in the character log, Brightbane is giving +7 COMPETENCE to all cha skills, which is where his error is coming from, it is not giving insight as all other properly working Command items are. It is not user error, it is coder error.
