Can multiclass characters gain Epic Boons

Are Epic Boons only available to players that take one class to 19 or could a multiclass character attain them without a DM giving it to them?

There has been some debate about this. In my case, I agree with the following interpretation:

No official ruling besides what the core rules say. Main key points why such multiclassed character can take an Epic Feat is;

• The Epic Boon Feat Prerequisite: Level 19+ is your total character level, not your level in a particular class.
• If you’re instructed to choose a feat and no category is specified, you can choose from any category. 

The threads I remember about this topic:

-  Epic Boon Eligibility confusion (the previous quote is from here)
- 2024 Epic Boons
- A question regarding the Epic Boon Feats

A multiclass character can take an Epic Boon in some fairly narrow circumstances. Specifically, they would have to be reaching a total character level of 19 (or 20) at the same time that they're reaching a class level with a class feature that grants a feat.

The "Ability Score Improvement" class features that provide feats don't place any restrictions on what kind of feat you can take with them; you just have to meet the prerequisites for the feat itself. Epic Boon feats generally have a prerequisite of "Level 19+", but that refers to character level rather than levels in any specific class.

So, for example, if you had 15 levels in Sorcerer and 3 in Bard (total character level 18) and took another level of Bard, you'd now be Sorcerer 15/Bard 4, for a total character level of 19. The 4th level "Ability Score Improvement" feature from the Bard class grants you a feat. That feature doesn't place any restrictions on what kind of feat you can take with it, so you can take any feat you meet the prerequisites for. Since your total character level is 19, you meet the prerequisites for most Epic Boon feats, so you can take one of those.

If, on your next level up, you took a level of Sorcerer, you'd then be Sorcerer 16/Bard 4. You get another "Ability Score Improvement" feature from the Sorcerer class at level 16, so you get another feat, which can be another Epic Boon feat if you want (since you still meet the Level 19+ prerequisite, as your total character level is 20).
