Coven Green Hag

The hag attacks twice with its claws and then uses Hex if not in beast form.

The hag magically transforms into a Large or smaller beast or back into its true form. While in beast form it retains its game statistics can't cast spells can't use Hex and can't speak. The hags Speed increases by 10 feet and when appropriate to its beast form it gains a climb fly or swim speed of 40 feet. Any equipment the hag is wearing or wielding merges into its new form.

Melee Weapon Attack: +5 to hit reach 5 ft. one target. Hit: 12 (2d8 + 3) slashing damage.

A creature within 60 feet that is not already under a hags hex makes a DC 13 Wisdom saving throw. A creature under an obligation to the hag automatically fails this saving throw. On a failed saving throw the target is cursed with a magical hex that lasts 30 days. The curse ends early if the target suffers harm from the hag or if the hag ends it as an action. Roll 1d4:

Charm Hex. The target is charmed by the hag.

Fear Hex. The target is frightened of the hag.

Ill Fortune Hex. The hag magically divines the targets activities. Whenever the target attempts a long-duration task such as a craft or downtime activity the hag can cause the activity to fail.

Sleep Hex. The target falls unconscious. The curse ends early if the target takes damage or if a creature uses an action to shake it awake.

The hag is invisible for 1 hour. The spell ends if the hag attacks uses Hex or casts a spell.
