Cause Fear: Should specify if caster is source of fear (for frightened condition)
Ceremony: Great spell, but I think component should be consumed for Bless Water. Might be interesting if each application had it's own component, some consumed some not. IE, Bless Water consumes 25 gp of silver. Marriage requires a 10 gp gold ring for each recipient (not consumed), atonement requires a 25 gp gem (consumed) etc. I might also change "Marriage" to be "Marriage/Fellowship," since it could be applied well to a fellowship commitment. (If that is not somehow too political...)
Chaos Bolt: Neat concept, but damage is low; people will use chromatic orb instead
Healing elixir: I like to think of mixing up the elixir and imbuing it with magic, rather than having it magically appear. To that end I think you could assume the vial is included as part of the alchemist's supplies. And I'd rather the school were transmutation.
Infestation: Random movement doesn't seem that useful, to burn a cantrip slot on.
Sense Emotion: Doesn't seem very useful
Snare: I would add that the target is "magically suspended" to avoid confusion about whether the rope itself is holding them up (and thus subject to being cut etc). Also kind of strange the creature is considered prone here. Ranged attacks on the target would have disadvantage?
Sudden Awakening: Awfully situational. How about adding an effect that any surprised target can act normally on their first turn of combat (if that turn hasn't yet passed).
Toll the Dead: Not sure about the name, but the mechanic is fine. Maybe "Death's Call"?
Virtue: Seems like a pain to keep track of, also not sure it would often be worth an action to cast.
Wild Cunning: I don't like how this steps on the toes of skills. It is also pretty situational. I'd rather it gave a bonus or advantage on a variety of skill checks related to wilderness.
Zephyr Strike: I like this, but there is a wording issue. For quite a while I was reading it that you got advantage (and the speed boost) only once per casting, not once per turn. I think the language is genuinely ambiguous. Try "On each of your turns until the spell ends, the first time you make a weapon attack you have advantage on the attack roll. Whether the attack hits or misses, your speed increases by 30 feet until the end of that turn." Assuming that is what you meant
