The PHB defines the charmed status with the following rules:
- A charmed creature can't attack the charmer or target the charmer with harmful abilities or magical effects
- The charmer has advantage on any ability check to interact socially with the creature
However, several spells and abilities use charm as 'complete control' over the victim.
In Awaken, it says the animal is charmed, full stop. Is this only the minor kind of charm? If so, at the end it chooses to remain friendly or not. What does that mean? It has the same status condition as charm forever? Or that it just likes you?
Examples of this are Dryad charm, dominate/anything, suggestion (for one sentence) succubus charm, animal friendship, bag of tricks, the list goes on. All of them describe the condition as charmed but you completely direct the targets action
