Class features level cap and Mythic Class features.

[Frostfire v3]

Hello everyone, i've registered just to ask this question that is troubling me a lot lately.

In my current campaign i'm playing a Death Knight, [Antipaladin variant from Genius Games] and all his class features have a level cap like:
"Deathly Boon" At 5th level, this spirit grants the weapon a +1 enhancement bonus. For every three levels beyond 5th, the weapon gains another +1 enhancement bonus, to a maximum of +6 at 20th level.

The mythic version [from the Mythic Heroes handbook] states: Mythic Weapon Divine Bond: The death knight infuses his
connection to deathly powers with his mythic energies. He adds
his mythic tier to his death knight level when determining the
effectiveness and duration of his weapon bond.

So does the mythic version increase the cap of the ability up to 30? Or it's still capped at level 20 making the mythic version crap?

The same thing can be applied with many others abilities that have the same wording and i couldn't find anything about this.

In general, if an ability says it has a cap at Xth level, then it has a cap at that level - even if other abilities help you reach that cap faster. If they raise the cap, they'll say so.

(Thus, it may help to retrain those abilities later on...)

[PossibleCabbage]

Generally speaking when rules text has a "to a maximum of x at nth level" clause, that clause serves to let the reader check that their math is correct, while the actual rule is what precedes it.

[Fuzzy-Wuzzy]

A strict reading agrees with GM Rednal, a "what did they really mean" agrees (IMHO) with PossibleCabbage. So it comes down to what kind of rules-reader your GM is.
