Commando

General Feat (Prerequisite: Level 4+)

You've seen life on the front lines of war in the bleakest of modern settings, granting you the following benefits.

Ability Score Increase. Increase your Dexterity, Constitution, or Intelligence score by 1, to a maximum of 20.

Crowd Control. When a Modern Firearm or Explosive (Bomb, Dynamite Stick, Fragmentation Grenade) you used forces a saving throw, you can use a DC of 8 plus your Dexterity or Intelligence modifier and Proficiency Bonus instead of using the base DC. Additionally, a creature that passes the save takes half of the damage rolled if the item would normally deal none.

Grenadier. When you throw a Bomb, Dynamite Stick, or a Fragmentation Grenade, the distance you can throw it increases to 120 feet.

Quick Toss. When you take the Attack action on your turn, you can throw a Bomb, a single Dynamite Stick, or a Fragmentation Grenade in place of one of your attacks.
