Master Bomber (5e Feat)

You have mastered the esoteric nature of fighting with bombs (See pages 267-268 of the Dungeon Master's Guide), gaining the following benefits:

As an attack, you can light and throw a bomb as if it was a ranged weapon with the two-handed property. This enables you to throw multiple bombs in one turn if you have Extra Attack or a similar feature.
A bomb you throw has a DC equal to 8 + your proficiency modifier + your Strength or Dexterity modifier.
You are skilled in crafting your own explosives. With access to appropriate tools, you can build a bomb in 1 hour by using a powder horn of gunpowder, or similar materials that cost 35 gp.
When you make a Dexterity saving throw against a bomb, you take half damage if you fail the saving throw, and take no damage if you succeed.
