Radiant Edge
Radiant Edge is a Kido-type skill essence in VV: Ultimatum obtained as a direct drop from the boss Lord Nivis, producing a blade whose color matches your reishi color.
Radiant Edge sits in the Kido group of skill essences - unlockable skills that drop from bosses and raids rather than being bought from the skill trees. Its acquisition is documented plainly: it is a direct drop from Lord Nivis, the frost boss tied to the Everwhite Enclave questline, meaning you must deal enough damage to qualify for the kill credit and then rely on the drop roll.
The one documented mechanical detail is cosmetic-adaptive: the sword the essence produces takes its color from your reishi color, so the skill looks different from player to player. Community documentation does not yet record the move's damage, cooldown, Reiatsu cost, or stat requirements.
Because Lord Nivis is also the source of the Frostvein Crystal needed for the Upgrade Shrine questline, farming him serves double duty - hunting Radiant Edge and progressing the shrine unlock happen in the same fights. Until fuller documentation lands, treat every unlisted stat as unknown rather than zero; details are subject to change per current documentation.
