Shadow

Three levels:

Shadow-Touched

The creature has a gray pallor. Its hair or fur, if any, tends toward dark and drab colors. Its eyes darken to nearly black. Its shadow seems more intense, despite the fact that ambient light levels are noticeably lower in its vicinity.

• +2 to all saving throws, attack rolls, skill checks, spellcasting checks, spell DC's
• Once/rd, add 10 shadow damage to any successful damaging attack or spell
• See through all darkness, including magical
• When standing in darkness or dimness, gain Fast Healing 10%/rd
• Resist (shadow)

Shadow-Infused

Shadows gather around the creature, curling around it like living tendrils, which protect the creature, but can also quest out to attack its enemies. Its eyes are pools of blackness, its voice resonates with an otherwordly bass. All light seems to pour into the creature, whereupon it is extinguished.

• +200% to max HP
• +5 to all saving throws, attack rolls, skill checks, spellcasting checks, spell DC's
• Once/rd, add 20 shadow damage to any successful damaging attack or spell

  • Shadow Jump: Teleport up to 10 squares; target location must be in dimness or darkness.

Void-Sworn

The creature seems comprised entirely of shadow, save for a dull, ultraviolet aura around its body, and two (or more) piercing, violet eyes. Light, hope, joy, and warmth seem to fall into its event horizon, erased from the universe.

• +300%
• +5 to all saving throws, attack rolls, skill checks, spellcasting checks, spell DC's
• Advantage to all saving throws, attack rolls, skill checks, spellcasting checks, spell DC's
• Can add 20 shadow damage to any attack or spell 3 times/rd. If it does not possess this many attacks per round, it may combine multiple uses on a single attack.

• When standing in darkness or dimness, gain Fast Healing 10%/rd

• Emanations
  • Gloom: Automatic once/rd, centered circle 20; area's light level decreases by one step (daylight -> bright light, bright light -> dimness, dimness -> darkness).
  • Void Zone: Automatic emanation 3; area is pitch black, even to natural darkvision. Creatures suffer 40 shadow damage on turn start in area (Fort DC 22 half). If they reach 0 HP in the area, they become shadow-infused, and are dominated by the Void-Swarn. Killing the Void-Swarn ends its thrall over them, and removes their shadow infusion, but returns them to a dying state.
