Grimarillion is designed toward merging multiple stand-alone mods into one single mod - how the classes and gear interact with each other is far beyond ASYLUM’s scope. There are no Satyr crafts for D3 characters, but you can craft the Jade Set beginning at level 30 that gives +2 to all skills (D3, Zenith, GQ, all of them) when you equip them both. Whether D3 characters can reasonably level through the game with their current gear is not something I care to test, but any issues with early-game skills being too weak should be taken up in the D3 thread.
One further point: the reason GQ and Zenith have those crafts is because they have no Epic or Legendary items early on that give +skills to any of their abilities. They have items that give +1 to all skills in those classes, but those bonuses don’t have much of an impact until Level 50 or so anyway, if only because you don’t have enough skill points early on for those bonuses to matter in any significant way.
