Druid Shapeshifting
Specialised form: You set your stats in whatever form you're most attuned to, be it cat, bear, stag, owl, or humanoid. Switching to your specialised form is guaranteed, but costs a turn action.

Unspecialised form: If you decide your character is capable of it, they can switch to any druid form by beating a 12 on a D20. No stat applies to this roll, but you can exert mana to improve your chances. When in a form you're not specialised in, all stats are 0 at max (you can nerf yourself if you like).

Metamorphosis
The Reward: Demonic Stats

You get 9 free stat points to distribute in the following four stats: Base Health for a demon is 48, just like a player.
 * Strength for melee attacks
 * Dexterity for evasion and speed
 * Stamina for resilience
 * Knowledge for magical potency

Mana is shared between forms, so you cannot have Spellpower in your demonic stats. To keep it simple you can't do any sacrificing of points like you can for a normal PC.

The Risk: Losing Control

It costs 5 mana to maintain metamorphosis each turn. If you run out of mana before you regain control, your demon takes control instead. Your character will be written off as dead, but you'll get to roleplay their demon as it tries to kill the party. This is non-negotiable, and a fundamental aspect of roleplaying a Demon Hunter.

The Escape: Leaving Demonform

You have to succeed in rolling below your remaining mana-count to quit demonform. The longer you release your demon for, the harder it will be to lock it back up.

Life-tap spells meant to recoup mana from health will take from your Elf form 's healthpool.

Channelling
You can delay finishing a spellcast to add one stack of your Knowledge bonus per turn. If you're damaged or have to move when channelling, you lose all your progress. If something goes horribly wrong like an enemy caster meddling, you can be harmed by the energy you've stored up. This would mean rolling without any bonus, against a roll that benefits from your stacked-up-stats.
