Unlike most rituals, Tempesta Scudo can be cast speedily. The necromancer performs a short and awkward dance that ends with her biting through her own lip and spitting the blood in a circle around her. All ghosts’ actions within the circle of blood are made at +2 difficulty.

To cast this ritual successfully, the necromancer must spend one combat turn performing the dance. At the end of the turn, she makes a Dexterity + Performance

roll against difficulty 7 (if done outside of combat, the difficulty is only 6). During the next combat turn, she bites through her own lips (taking a level of bashing damage) and spits (spending one blood point). Then the normal ritual roll is made to see whether the power takes effect.
