Dunno. +4 to Str and Con is probably stronger than your second favorite epic boon. Or any of the paladin transformations.That definitely seems like an exploit to me. I'd veto that, as I strongly doubt that it's the intent and even if the wording permits it, it's bad design. I very strongly doubt the intent of epic boons is to make multi-classing basically mandatory.
If that's RAW, which again I think is unlikely, I'd instantly overrule it.
Ranger capstone is terrible though. Multiclass rogue 1
You also need to line up the levels to get a second epic boon. Warlock 13/bard 5 isn't getting any.
