I don't want to build my character entirely because I want to see what scenario they'd be in, but I have two powers I'd like to run past you.

[i][u]Absolutely Superb![/u][/i] ~ With a single compliment the entire world may change. Whenever an ally succeeds at anything they may be complimented, and when they are complimented reality reorders itself so the greatest success possible under the circumstances was achieved. To put it in RPG parlance, he can change any allies ordinary success into a critical success. The ally must be able to hear the compliment for the effect to go off, and he can not apply this effect to himself. 

[i][u]A For Effort![/u][/i] ~ While his first ability is a success magnifier, is one is a failure minimizer. When any ally fails at something he can tell them they were just doing their best and the consequences of their failure are retroactively minimized to the smallest degree possible under the circumstances. If his first power is changing 1 into 10, this one is changing -10 into -1.

Sorry taking a while to get back to you. I like the ideas, although their strength and the whole rewriting reality thing bring to mind another aspect of epithets: epitomes.

Epitomes are the flat-out most powerful use for any epithet. They go beyond the meanings of the word for the user and touch the core concepts related to the word--superset rather than subset. They are extremely rare and can be developed only by individuals with the toughest constitutions, sharpest wits, and creative minds after countless hours of training and use.

For instance, the epithet Sundial might just be able to tell the time of day, and the weather. But the epitome of Sundial can control the progress of any ongoing process with a beginning and end, accelerating, stopping, or reversing.

This isn't to say that I want any epitomes running around, of course. I mention it because maximizing successes and minimizing failures through rewriting reality is pretty incredible. Could be broken.

Other uses of superb could avoid that risk. It can mean excellent, impressive, splendid, top-class. It could be used to improve the quality of materials or devices, refining them, or just making them look better or flashier. I personally have only ever heard people say the word in reference to really good food, so that could be an example. Maybe the character is a chef who can make food so good it confers miraculous, magical effects!

Just spitballing here, of course. But hey, it's fun.
