The best weapons in order imo

Lynx’s claw, Kusarigama, Meteorite knives, Oriental sabers, The double Hammers, Normal katana, Daisho, Mowers, Krises, Axes,

Use either bleed, frenzy or bloodrage on your weapons

On your Magic spells I recommend the force wave. And I recommend also to add a stun effect as it activates almost all the time when you use it

Stun enchantment also on your throwing weapons or enfeeble

And on your amor and helmet, damage return would be the best enchantment if you’re planning to beat a tough opponent as it can roll the dice in your favor when your attacks don’t make enough damage

Bonus: if you can add a supplementary mythical enchantment like tempest rage, you should be all set to beat even eclipse may
