(Rhonari) Linebind Oathkeeper

Prerequisite: Rhonari heritage or DM approval

Increase your Wisdom or Charisma by 1, to a maximum of 20.

When an ally within 30 feet fails an ability check or saving throw while attempting to keep an oath, defend a community, resist intimidation, or protect another creature, you may use your Reaction to allow that ally to add your Proficiency Bonus to the roll, possibly turning failure into success.

You can use this Reaction a number of times equal to your Proficiency Bonus, regaining all uses when you finish a Long Rest.
