Gentle Giant (5e Feat)
From D&D Wiki
Prerequisites: Large size or larger
You have a knack for putting others at ease with your large size, rather than scaring them. You gain the following benefits:
- Your Charisma score increases by 1.
- You gain proficiency with the Persuasion skill. If you are already proficient in the Persuasion skill, you may add double your proficiency bonus, instead of your normal proficiency bonus, to ability checks made with that skill.
- You have advantage on Persuasion checks against creatures that are at least one size category smaller than you.
