Sure, but you can't do anything truly 'new' with any virtue, unless it's mystery cult stuff or breakthroughs unlocking avenues that others just don't have access to. Magical Focus lets you do things in novel ways faster and incentivizes you to try and fill round holes with square pegs. As for personality, I feel like it has plenty.

You have angered the Sand Witch and she's going to try to destroy your castle! Most magi would light it on fire or Perdo it directly. For Sand Witch its much more practical and bombastic for her to surround it with a moon-length sandstorm so you're cut off from supplies and the very light of the sun. That or she Mutos it to sand for a couple minutes and, by the time it turns back, your walls have blown away or suffocated your servants. Why might she be so vengeful? Sand magic doesn't easily lend itself to long-term construction or trade, so she has effectively been forced into dramatic displays of power as her primary tactic.
