If you find a daedalus hammer, here's a small tip for beginners who get all the way to hades from a vet of the game:

If it has the option to choose for your attack to strike twice instead of once? TAKE IT.
Enemies that revive themselves will have their "souls" killed off faster by spamming the respectively X2 buffed attack if you have sufficient boons and upgrades. Don't use the anvil before facing hades or you'll lose this effect to an gamble of benefits, and you'll need the strike twice for those hordes of rats and satyrs.

Pairing it with dash nova, another daedalus hammer artifact, makes it an absolute decimation combo.

You must be thinking about Double Edge (Stygius), Double Nova (also Stygius), and maybe Pulverizing Blow (Aegis), all of which I generally like in spite of the tradeoff of losing knockback. And although there is also Twin Shot (Coronacht), these kinds of Daedalus Hammer Enchantments are actually quite rare among all the possibilities for all the weapons.

Also, what about Serrated Point, which deals a triple-type attack? It's basically my favorite Varatha Hammer Enchantment, but I'd only recommend it to those who are good at dash-striking. Otherwise, it should be passed up since it reduces the dash range. Triple Bomb (Exagryph) is a nice one as well.

(Also, I actually disagree that Dash Nova is good for beginners, as it screws around with player movement — better once you have a handle on character movement in general.)
