[@SimplyJohn] That is much better John, thank you for your speedy reply and pleasantness against my rougher nature of critiquing, I'm a much fun person when I'm not "business" seriously.

Two things really-

One: Reusable Resource, yes, just keep in mind this is a desert environment, it won't take that long for it the water to fizzle out or soak in, but, circumstance always. Like the salt flats, probably would eat spilled water faster than a starving child with a bunny.

Two: There is a 2:1 ratio that you must adhere to, unless something is won in the little contests I do (riddles, clues, prizes.) That is: Strengths/Abilities to Weaknesses. You're weaknesses can exceed your Str/Abil ratio, but not vice versa. This prevents too many "perks", granting overly absurd powers and prowess, which is why many of our character have simple-focused skills sets. 

Example Ability: "Huntress" could combine her keen eye for "natural detail", like spotting something out of place, with her ability to accurately gauge the lay of the land to stalk and hunt her prey.
