Too much anime, but a term that would help your tiny heroes who want to wield BIG weapons might be helpful here.
Prerequisite(s): small size
You might be small, but that doesn’t mean your weapon has to be! You gain the following benefit:
- Increase your Strength or Consitution by 1, to a maximum of 20.
- When you wield a heavy weapon, you no longer have disasdvantage.
