Made a GIth Spell Sword, What is a good high dex weapon to use?

[T'is The Way]

As the title says, I have been using The fire Sword from the first boss fight and want to get something dex based for my gith spell sword.
Any recommendations?

If you're thinking early... Phalar Aluve's available during Act 1 and is a +1 longsword with finesse and useful ability.

There's a +2 finesse halberd (!) w/ a Whirlwind Attack ability you can buy in Act 3.

Rapiers, shortswords, scimitars and daggers are all finesse-tagged as well, so you can use Dexterity as your attacking stat.

Phalar Aluve for sure. Not much in act 2 . I guess the Mizora quest reward (rapier) one that comes to mind . my dex based char's are always ranged. You have duelist prerogative in act3. Blood Thirst and Crimson mischief (Orins weapons) are insanely good though thats at the very end of the game
