Enchant Scarecrow (Bomb)

The user spends an hour performing a ritual, after which they touch a standing scarecrow and imbue it with magical power. The Scarecrow will chase enemies or intruders who enter a range of 50 ft., if not designated as welcome by the caster. Upon reaching the target, the scarecrow explodes, dealing 8d6 force damage in a 20 ft. radius sphere. The Target must make a DEX Save equal to the Caster's Spell Save DC. On success, the target takes half damage. If the remnants of the scarecrow are not destroyed, it reforms in one hour and returns to its designated location. Casting this spell at a higher level adds an extra 1d6 damage per spell level beyond level 3.
