Tool Expert (5e Feat)
From D&D Wiki
You have honed your proficiency with particular tools, granting you the following benefits:
- Increase 1 ability score of your choice by 1, to a maximum of 20.
- You gain proficiency with 2 tools of your choice.
- Choose two tools in which you have proficiency. You gain expertise with those tools, which means your proficiency bonus is doubled for any ability check you make with them. The tools you choose must be ones that aren’t already benefiting from a feature, such as expertise, that doubles your proficiency bonus.
