Currently trying to brainstorm stuff for a norse demon/wendigo druid subclass and I'm trying to think of thematic options

Thinking of a new wildshape option which gives bonus stealth/stalking abilities and possible extra necrotic dice with melee attacks, OR being able to speak while in wildshape form and the ability to cast necromancy/illusion/enchantment spells. Any thoughts for other features like level 6 and 10 bonuses?
