Targets of your darkness spells radiate darkness.
Prerequisite: Tenebrous Spell.
Benefit: An umbral spell gains the darkness descriptor. As long as the spell is in effect, the creature or object affected radiates darkness in a 10-foot radius, reducing illumination similar to the effects of the darkness spell. Nonmagical sources of light, such as torches or lanterns, do not increase the light level in this area. Magical light sources only increase the light level in an area affected by an umbral spell if they are of a higher level than the umbral spell’s unmodified spell level. This effect does not stack with itself or with any other effect that creates darkness.
Level Increase: +2 (an umbral spell uses up a spell slot two levels higher than the spell’s actual level.)
You cannot use this feat on a spell with an instantaneous duration or a spell that does not target a creature or object.
Protection from the dark times of Earthfall was but one of Zon-Kuthon's “gifts” to the terrified people of Nidal. To ensure the grip of his Umbral Court would remain forever unbroken, the Midnight Lord bequeathed to his mortal servants the secrets of blending shadow and magic. Though most shadowcasters practice wizardry (and indeed, wizards can choose the shadowcaster archetype if they wish to fully embrace this style of magic), Zon-Kuthon's gifts can be used by any spellcasting tradition. Beyond the borders of Nidal, cabals practicing shadow magic haunt the fringes of Galt and Taldor, some in service of the Midnight Lord, and others serving only their own lust for power.
