Deathnote

You touch a single piece of parchment and imbue it with the power to control life and death. While the magic is active, you can write one name on the parchment and specify the exact description of that person's death. At the end of the minute, the magic will take effect as long as you are imagining the face of the intended target (so the wrong person is not affected). The spellcaster must make an Arcana check (DC = 10 + proficiency bonus + spellcasting ability) to effectively cast the spell. The DC increases by 2 for each successful use of the spell.

If the spell fails, the parchment is consumed and the same person cannot be targeted by the spell again
