Companion Boon

Characters have spent enough time working with their adventuring companions that their own skills rub off on their friends.

A 7th level or higher a character is granted one of their fellow adventurers a boon. No character may benefit from more than one boon gifted by a companion. The boon is like a leveling up "gift" the character gets to share with a companion by training them in a bit of what they do. Here are the boons based on the boon-giver's starting class:

Class	Boon
Artificer:	Train one companion in learning one infusion into a nonmagical item.
Barbarian:	Train one companion to add +1 to AC when not wearing medium or heavy armor.
Bard:	Train one companion to grant one bardic inspiration die (d6) per short or long rest.
Cleric:	Teach one companion a cleric cantrip.
Druid:	Teach one companion a druid cantrip.
Fighter:	Train one companion to add +1 to melee weapon attacks.
Monk:	Train one companion to add +5 ft to their movement speed.
Paladin:	Permanently increase one companion’s maximum HP by 5.
Ranger:	Train one companion to add +1 to ranged weapon attacks.
Rogue:	Teach one companion Expertise in one skill of the recipient's choice.
Sorcerer:	Teach one companion a sorcerer cantrip.
Warlock:	Teach one companion a warlock cantrip.
Wizard:	Teach one companion a wizard cantrip.

• Artificers who train companions only teaches them the ability to infuse magic into nonmagical items, not a specific infusion. When a companion learns from an artificer the recipient picks the infusion.
  
  
• Spellcasters train their companions in the art and science of magic itself, not in particular spells, so they do not need to personally know the cantrips they teach their companions.
  
  
• Rogues train their friends to hone their own skills, so the rogue doesn't need to be proficient in the skill they grant expertise in.
