A multiclass character uses character level to determine the damage of a cantrip. This was added to the Sage Advice Compendium (page 4) as of its initial release in 2015: If a character has levels in more than one class, do the character’s cantrips scale with character level or with the level in a spellcasting class?
Can you use spell slots for cantrips?
Cantrips are free magic — if you know a cantrip, you can cast it as many times as you want, whenever you want. Cantrips don’t need to be prepared, and they don’t use up Spell Slots.
When do cantrips use your character level or class?
I saw a tweet from Mike Mearls that addresses this, Cantrips are intended to use your character level. The example give I believe was a lvl 20 high elf barbarian being able to cast firebolt at max level. The spells refer generally to character level and not spell caster level. The Sage Advice Compendium confirmed this when it was published.
When does a spell assume a higher level?
When a spellcaster casts a spell using a slot that is of a higher level than the spell, the spell assumes the higher level for that casting. For instance, if Umara casts magic missile using one of her 2nd-level slots, that magic missile is 2nd level.
Can a spell be cast at a higher level slot?
Misty Step is way more than merely a bonus move (a Dash). It allows you to get out of being surrounded or grappled, and allows you to move without jump/climb/swim/balance checks. Can any spell be cast at higher level slot or only those that specify an effect at higher level?
Do you have to be a spell caster to use a cantrip?
