Creeping Shadow

Electrified Bomb. When hit with Lightning damage the Creeping Shadow's explosion damage is doubled.

Infectious Seeds. When a creature is hit by the Explode attack, they make a DEX save equal to a DC based on the damage direction (seen in the Explode description) if they fail the save then roll 5d4 to determine the amount of seeds in the creature. If left in the creature for one week the creature will slowly turn into a Creeping Shadow within 1d4 days after the week. If the creature dies from the original explosion it gains 3x the amount of seeds and if left for 1d4 days in the body it will become a plant unable to move that can shoot precise and penetrating Infectious Seeds into the target (1d4 seeds from the unmoving plants)

Seeds can be removed with: "Remove Curse" or an effect that removes Disease

Explode. The Creeping Shadow self-destructs. Roll a d100 to determine where most of the damage is going (1-25 is North, 26-50 is East, 51-75 is South, 76-100 is West). 20 ft diameter Exploding. 

If a creature is in an area not selected for most of the Creeping Shadow's damage, it must make a DEX save with a DC=18 (the save has disadvantage if the roller was surprised) on a success they take half damage along with avoiding the creature's infectious seeds, and on a fail they take full damage and are implanted with the infectious seeds. The damage for the area not selected is 8d6 force damage.

If a creature is in the area selected for most of the Creeping Shadow's damage, it also must make a DEX save however with a DC=23 (the save has disadvantage if the roller was surprised) on a success they take half damage along with avoiding the creature's infectious seeds, and on a fail they take full damage and are implanted with the infectious seeds. The damage for the area selected is 20d10 force damage.
