Mentor

You’re a skilled tutor of military training. You gain the following benefits:

• When you are wielding a martial weapon that you’re proficient with, allies within 20 feet of you that can see you are proficient with that weapon for as long as you are wielding it.

• You can tutor others in weapons you are proficient with. You may spend an hour tutoring one creature in using one martial weapon you are proficient with, provided you have access to two weapons of that type. At the end of the hour, that creature can attempt a Strength (or Dexterity, if the weapon is ranged or has the finesse rule) or Intelligence    check, adding your proficiency bonus, with a DC of 18. On a success, the creature you trained becomes proficient with the weapon you tutored it with.
