Shadow Step

The svartalfar killer fades into shadow, Strides up to twice its Speed, and reforms.

This movement doesn't trigger reactions, but the svartalfar killer must begin and end in an area of dim light or darkness.

Sneak Attack

A svartalfar killer deals an extra 2d6 precision damage to Off-Guard creatures.

Spell-Imbued Blade

The svartalfar killer chooses Acid Splash, Ignition, Enfeeble, or Shocking Grasp and makes a melee Strike.

If the svartalfar killer hits, they cast the chosen spell through the weapon at the same target. The spell's attack roll is the same result as the Strike.
