I have a character in my game who is having fun imagining himself army crawling around our druid's fog cloud, planting claymores and lobbing grenades. To that end I am looking to create a spell that reflects a bit of that power fantasy.
I tried to balance the spell by looking at Magic Stone and Scorching Ray for inspiration. I would like the damage of the spell to be relevant as a turn-to-turn weapon in a fight at early levels, but really shine as a distraction and trapmaking tool.
Casting Time: 1 action
Components: V, S, M (an acorn and a bit of peat moss)
Duration: 10 minutes
A magical bandolier of vines grows about your chest with three fist-sized acorns hanging from it. As an action, you can take one of the acorns from the vine and remove its cap, arming it. As part of this action, you may throw the armed acorn at a point within 60 feet, where it explodes. Any creatures within a 5-foot radius of that point must make a Dexterity saving throw. On a failed save, a creature takes 1d12 fire damage, and half as much on a successful save.
If any armed acorns are dropped, hit, crushed, or stepped on, or take any damage, or have not exploded when the duration of the spell ends, they explode, with the same Dexterity saving throw and the same damage as described above. Any acorn that takes fire damage explodes, whether it is armed or not.
When the duration of the spell ends, the bandolier and any unarmed acorns wither and crumble into nothing. You may have only one bandolier and set of acorns at a time. If you cast this spell again while you still have a bandolier or acorns, they crumble into nothing.
At Higher Levels. When this spell is cast using a spell slot of 3rd level or higher, the bandolier grows one additional acorn per slot level above 2nd.
Available on the Druid and Ranger spell list.
