Drauth a Basic 5th monster

Here's my first shot at a 5th edition Basic monster:

Drauth Medium Fey, Neutral Evil
Armor Class: 14
Hit Points: 22 (5d8)
Speed 30 ft
STR: 13 (+1)	INT: 12 (+1)
DEX: 13 (+1)	WIS: 11  (+0)
CON: 10 (+0)	CHA: 12 (+1)
Skills Perception: +4
Senses: darkvision 60ft., Passive Perception 14
Languages: Goblin, Elf
Challenge 2 (450 xp)
Shape Change- Grow, when the Drauth has advantage it may grow, effectively gaining a point of Strength and a foot in height each round.
Attacks
Sword, Weapon Attack +3 to hit, 1d8+1
Reactions
Regenerate slowly, regaining double HP per short rest
Drauth always save at an advantage vs Magic Drauth are a race of gaunt subterranean dark elves that dwell in underground kingdoms but also hide among other races as chengelings using their shape changing powers.

I ampretty sure it isn't perfect as i said above it is my first attempt at making a monster for 5th edition play.  I might revisit this as my knowledge of that edition grows (if it does).  My old-school version is here in my previous post.

Edit: chnages the regeneration entry, healing is really generous in 5th, i';m not sure somehtign like slow regeneration actually works in the game.
