Which Is Better?

It mostly depends on your build.

But Memento for me

 

Memento for me as well as I'm using the spell damage aside of the mana regen.
What else do you want to use/are you using?

 

Nothing's really final, but Blue Mask, Libra, Dark Channeler, and Ethereal with 2 thunder powders.
I'd also am planning on adding some thunder powder to my armor, since my thunder defense (with Memento) is 5.

 

I would prefer riverflows 24% water if I was on a budget build(and I never am sadly)

 

If you want to use Memento, reroll it pls
2/4 Mana 56 Raw Spell Dmg (55 is lowest)

 

So, I re-id'd it and got max mana regen xD
definitely going with Memento.

 

Spell Dmg?

 

ugh I logged out.
