Epic Boon Eligibility confusion

Quote from SmiteMakesRight_3_5 >>

Also note that if someone were to publish an Epic Boon feat that did not have a character level requirement, you could take it at class level 4, 8, 12, 16, or 19, regardless of character level. Character level 19 is a requirement of specific Epic Boons, not of the Epic Boon feat category. It just happens that all currently published Epic Boons require character level 19, but that is not actually a requirement of the feat category.

This raises the question, why is there a separate Epic Boon Feat category at all then, if there is no difference at all between general feats and epic boons.

My opinion is that Epic Boons are for single class characters and are only attainable from 19th level up in a single class. They are not attainable by multiclassing and adding up different class levels to eventually total 19 character levels.

This is a house rule. Every currently published Epic Boon has a requirement of character level 19+, not class level 19+. There is no support in the rules for your opinion, so it is clearly in house rules territory. That's fine but be clear about it.

The Multiclass rules also reference character level in a few circumstances, but only where the general rules reference level ambiguously.

• Experience points to gain a level is based on your character level, not an individual class's level.
• You only get the maximum value for you class hit die at character level 1.
• Your proficiency bonus is based on you character level rather than the sum of your bonuses from your class levels.
• Cantrips improve based on your character level not your class level.

Epic Boon feats already reference character level so they do not need a call out in the Multiclass section unless they wanted to block them. There is no call out so a Wizard 15 that just leveled up to Fighter 4 (character level 19) is eligible for an Epic Boon. Leveling up to Wizard 16 allows for a second Epic Boon. This is RAW and anything else is a house rule.

Organizational choice. It also gives the option to specify a General Feat versus an Epic Boon feat. There may have been plans to do so in certain cases, but I am not aware of any.

It doesn't change the fact that when you get a feat choice at level 4, 8, 12, 16, and 19, no feat category is specified so you can choose from any feat category as long as you meet the requirements for the individual feat.

I think some people dislike the idea of attaining two epic boons due to a perception that it would be overpowered. However, there are costs to achieving that, especially, for full-casters, sacrificing access to 9th level spells.
