Cruces Shifting is a means by which an undead entity uses their undead Essence Pool to shift their manifestation. Undead who consume Essence can store the it and use it to shift what was once their physical properties – improving them on a 1:1 basis, improving their Undead Tenacity, or gaining 1/3 their normal movement.
Action of Shifting: Shifting is performed as either an Attack, or Reaction – whichever is fastest or most useful.
Shifted Focus: While the effect is running, no Hunger checks need to be made.
