Throwables

If you're looking for a more grounded area of effect attack, then Throwables might be useful to you. These include several types of bombs with different properties and effects. Similarly to spells, it is assumed that a creature using a Throwable can accurately throw it within range.
Besides being thrown, Throwables can also be fired from a Hand Cannon to double their effective range.
Explosive Bomb Weight: 1lb

All targets in a 15ft diameter sphere must make a Dexterity Saving Throw. On a fail, targets take 3d8 Explosive Damage and are deafened for one round, or half damage on a success and are not deafened.
High Explosive Bomb Weight: 1lb
Range: 60 feet
Specializes in delivering a devastating blast, but in a smaller area. All targets in a 10ft cube must make a Dexterity Saving Throw. On a fail, targets take 4d8 Explosive Damage, are deafened for one round, and are knocked prone. Targets take half damage on a success and are not deafened or knocked prone.
Low Explosive Bomb Weight: 1lb

Shrapnel Bomb Weight: 1lb
Range: 60 feet
All targets in a 25ft diameter sphere must make a Dexterity Saving Throw. On a fail, targets take 3d8 Piercing Damage, or half as much on a success. Creatures behind half-cover automatically succeed the saving throw, and creatures behind 3/4 cover and full cover take no damage.
Incendiary Bomb Weight: 1lb
Range: 60 feet
All targets in a 10ft cube must make a Dexterity Saving Throw. On a fail, targets take 3d6 Fire Damage and are caught on fire. On a success, targets take half damage and are not caught on fire. While on fire, targets take 1d6 Fire damage at the start of their turn until they use an action to extinguish the flames.
Stench Bomb Weight: 1lb
Range: 60 feet
Duration: DM chooses duration based on wind speed
Creates a 20ft diameter sphere of stench. Creatures caught in the stench must succeed on a Constitution Saving Throw DC 15 or become poisoned (Disadvantage on ability checks and attack roles) until the creature(s) leave the cloud.
The duration of the stench depends of the wind speed and the DM's discretion. Generally, the cloud will last ten rounds with no wind, six rounds with light wind, four rounds with moderate wind, and one round with heavy wind.
Smoke Bomb Weight: 1lb
Range: 60 feet
Duration: DM chooses duration based on wind speed
Creates a 20ft diameter sphere of smoke. Creatures in the smoke must succeed on a Dexterity Saving Throw DC 12 or lose sight of opponent(s) and are blinded. (Attack rolls against the creature have advantage, and the creature’s attack rolls have disadvantage).
Creatures outside the smoke lose sight of those caught inside as well and treat it as a Lightly or Heavily Obscured area depending on the duration and wind. The duration of the smoke depends of the wind speed and the DM's discretion.
Generally, the smoke will last ten rounds with no wind, six rounds with light wind, four rounds with moderate wind, and one round with heavy wind.
