Mage/Dark Wizard Water Mage Ring Help

I recently got told of a build to do, and it looks amazing.
The only problem is that it takes 4 hive items. 3 take water tokens, and 1 takes a master token.
I've saved up a water token and a master one from my archer build, and I will be getting another water token from my mage.
I need 1 more water token, which I cannot achieve at the moment.
Does anyone know what water accessory I can do? I need high mana regen/steal.
My build is: https://wynndata.tk/s/CtOvZJ
Planning on getting rid of one Moon Pool.
If there is any other items I should transfer/replace that would be nice to figure out. Possibly finding a better helmet and then getting the second Moon Pool is an option.

 

Replace both Moon Pools with Black Catalyst x2

Wynndata doesn't show Set Bonuses

Black Catalyst x2 Bonus:

2/4 mana, 10% spell, 50 Raw Spell, 20% xp bonus, and 150 HP
Set Bonus will only show in the compass btw, not when you hover over the item; that's the item's gimmick.


Replace Hive Wand with Requiem.

 

You have way more than enough mana. Focus more on spell

 

Alright, thanks guys!
