Just the lvl 85 techs will empower you to beat Hades without much effort, no matter how your gears are.
From what I have seen and heard, full mage build is put to test towards the end of Ragnarok and further. I've not seen any BR of pure mage beating Skuld yet(it could have been done before, but I'm sure it's very rare).
If you are determined to play pure mage and if you are patient enough to get all armors/cloaks max enhanced/enchanted, along with books and horns, along with G1-1 weapons/mounts(if possible), then yes you should have a chance.
It's the slowest and most expensive path, so you should be prepared for what to be expected
Nevertheless, Heph is a must-have for Poseidon and he's worth triple wash and any sort of investment you can give.
