Adamus could possibly be somewhat overpowered at the end of the game, yes. Depending on how high your attack is at the time, you could get a huge damage bonus. At the moment I'm looking at how to fix Elly and Gendalf, the latter has a bit of a problem as there is no "-X% leadership req of all units" item mod, there's only a handful specific ones which combined do cover a lot of the units but not all of them. A possible workaround could be to change the parameters of the function for griffins by expanding it to all units but this would mean that I would have to completely change that griffin banner which gives -30% leadership req for griffins. Not a big price since I reckon not many people use it but I'd rather see I didn't have to make compromises to make something work. The actual functions are probably hardcoded so at the moment I don't see any alternatives other than changing what the baby does. Thoughts?
Oh and as a side note, making new babies probably shouldn't be much of a problem, if anyone has any nice ideas let me know. Haven't tested it yet though, will get around to it once I finish the game (in a day or two).
