Squire of Gawain

The young Sir Gawain, known for his supernatural day-strength, healing abilities, and overall charm, has mentored you and taught you (almost) everything he can. You have a +1 to your charisma score.

Daylight
Gawain has given you a glimpse into his strange sunlight-controlled strength and shown you how to harness some of its abilities. In combat, as a bonus action, you can enter a state of heightened strength, granting you advantage on your next attack roll. You can use this feature a number of times equal to your Charisma modifier (minimum of 1), you regain all expended uses of this feature after a long rest, and it lasts for one minute when used in combat. While Daylight is active, depending on the time of day, you gain a number of abilities:

Dawn: You have resistance to radiant damage.

Noon: You have all the effects of Dawn and Sunset, and your melee attacks deal an additional [roll]1d4[/roll] radiant damage on a hit an amount of times equal your proficiency bonus (minimum of 1). You also have advantage on strength checks. The damage increases to [roll]1d6[/roll] at level 10.

Sunset: You can use your bonus action to heal a creature you can touch, restoring hit points equal to your proficiency modifier + your Charisma modifier (min 1). You can use this ability a number of times equal to your proficiency level.

Twilight: You have disadvantage strength checks and saves until the effect ends.

Midnight: You cannot use Daylight.

The Disrespect!
After watching Sir Gawain's "polite" interactions with other knights, you've learned a thing or two. You gain access to the vicious mockery cantrip and have advantage on intimidation checks used to insult or sass someone, but be warned! When you use this ability, roll a D20. Depending on the score (DC set by the DM), there is a chance the target will become offended and challenge you to a fight to restore their honor.

The Knight of Maidens
As a squire trained by Sir Gawain, you managed to pick up some things from watching him interact with others. You've gained a natural charm and charisma that can sway others to your cause. You gain half-proficiency in Persuasion and Deception, and at 6th level you gain full proficiency. When you make a Charisma (Persuasion) check to charm someone friendly with Sir Gawain, you have advantage on the roll. However, if you're attempting to persuade someone Sir Gawain has scorned, you have disadvantage. 

Close
As Gawain's Squire, you've spent a lot of time together. This means Gawain is more likely to open up to you than other people, so long as you're in his goodwill. You have advantage when persuading or using insight on Gawain.

 Patience
You can't always rely on Daylight.
You know how to heal wounds of the flesh the old-fashioned way. This ability takes a full hour and heals an ally of half their HP without using any materials. At level 10, you can restore them to their full health.
