From a point of the casters choosing that they can see clearly a small ebony black flower with a red aura appears. Un a 30ft radius from that flower, all plant life is immediately killed off, leaving behind dusty remains and creatures who have intent to harm the caster are plagued with fatigue and all dexterity based roles are made with disadvantage. The more enemies in the afflicted area, the bigger the flower gets. If the enemies are in the area for 5 seconds, they take 2d6+3 Necromancy damage and this damage increases by one d6 for each enemy in the area.
