D&D Avengers: Maximoff Twins

Long time no talk! I've been busy getting ready for a new job at a new school and its has been a mess. Actually, today is my first day back with kids and it was an adventure. Anyways, time to finish translating the Avengers to D&D characters because...well I started, I might as well finish.

Pietro Maximoff is just the Way of Celerity Monk I made back for Wally West, but with a Criminal or Urchin background.

Martial Arts

Gear: a shortsword, an explorer's pack, 10 darts, a small knife, a map of Sokovia, a token to remember your parents by, and a set of common clothes.

Leveling Up Pietro: Alright, so leveling up Pietro, up his Dex as much as possible and grab the new Way of Celerity path I made. He should be a punching machine who is always in the right place. Good luck getting away from this speedster. I'd like to see him and Wally duke it out. 

Now its time for his sister Wanda. She is basically a straight up Wild Magic Sorcerer (wow I'm not doing much homebrew this time). Great idea! New feat called Volatile. Similar to the Magic Initate but allows you to overcharge the spell you learn. 

Volatile 

You have trained hard to bring out an explosive power in your spells.
Prerequisite: Able to cast 1-st level spells

• Using this feat, you can cast a spell you know at one spell level higher without using a higher level spell slot. For example you could cast a 3rd level fireball as a 4th level fireball, but using only the 3rd level slot. You must finish a long rest before you can use this ability again. 
• Your volatile nature channels your energy at the expense of your health. As a bonus action, you can expend a hit dice and add its damage to a spell attack. 

Wanda Maximoff
Level 1 Human Urchin Sorcerer
Str 10 (+0), Dex 10 (+0), Con 10 (+0)
Int 14 (+2), Wis 14 (+2), Cha 16 (+3)
HP 6, AC 10, HD 1d6

Saves: Con +3, Cha +5
Speed: 30 ft.
Languages: Common, Orc, Giant, Goblin
Skills: Deception +5, Insight +4, Persuasion +5, Sleight of Hand +2, Stealth +2

Quarterstaff +2, 1d6 bludgeoning, versatile 1d8
Dagger +2, 1d4 piercing, range 20/60, finesse, light

Feat: Volatile
Sorcerous Origin: Wild Magic (Wild Magic Surge, Tides of Chaos)

1st-level spells: charm person, thunderwave 

Gear: a quarterstaff, an explorer's pack, two daggers, an orb, a small knife, a map of Sokovia, a token to remember your parents by, and a set of common clothes.

Leveling Up Wanda: Pump her Charisma and maybe grab some feats to make her a little less squishy. Her spell choice should center around hypnosis and telekinesis. This can include some illusion effects that target only one creature and thunder spells that simulate telekinesis, like I did with thunderwave. She should be a pretty fun character.
