Doom

R: 50 ft; T: creature; D: concentration

A chill creeps up the target’s spine and their gaze is locked to yours. At 3 [dice], you must loudly proclaim your hatred of them for 3 Rounds without being interrupted or breaking line of sight. At the end of the 3rd Round, they die, no Save.

You must truly hate the target for the spell to work. Even a sliver of pity cancels the spell.
