- Can certain classes replace cantrips with other spells when they level up?
- How to allow cantrips to be changed
It seems that everyone has agreed that once learned, a spellcaster can not swap out/change/replace their cantrips. To allow so would have to be under some house rule.
However, while researching a new character build, I found this in Xanathar's, under Divine Soul Sorcerer:
Your link to the divine allows you to learn spells from the cleric class. When your Spellcasting feature lets you learn or replace a sorcerer cantrip or a sorcerer spell of 1st level or higher, you can choose the new spell from the cleric spell list or the sorcerer spell list. You must otherwise obey all the restrictions for selecting the spell, and it becomes a sorcerer spell for you.
So there is a rule in the books specifically stating that cantrips can be replaced. As stated, this line only occurs under the Divine Soul Sorcerer, but it doesn't sound like replacing cantrips is something only they can do. Just that when replacing them, they need to follow special rules.
So I'm opening up an old question to see if we get a different answer, based on this phrase.
Can spell casters change out cantrips when they level up, just like 1st level and above spells?
And if not, how can you explain the line from Xanathar's?
