Water Manipulation

Would Brewing Mastery be a perfect skill for a character with water magic/hydrokinesis

And would this hydrokinetic use their power to make potions or elixirs.

Note: I'm thinking of changing the powerset of Devil Blue of the Devil Defenders into something that fits the color blue, what do you think?

If a user has ice manipulation, cold manipulation, water manipulation, absolute potential, absolute intelligence,and ability transcendence,Absolute regenaretion how strong will he be? ıwant longf answer pls.

What the title says, i'm just bored.
