File management, paper pushing and a small side of somewhat shady business dealings. Since Roo isn't an amazing fighter she tends to help out with small causes by finding otherwise slightly seedy paper trails left by less than reputable people. If you did a bad boy thing in the past and it was written down somewhere chances are Rooen can find it, even if she has to piece together ripped or chard bits of parchment. Her room and board are covered by the company she works for as a guild historian and record keeper, she travels all over looking for informative books or information to stock the company with so they have a decent pull of references for any subject. Think of an over zealous librarian. Social and cultural exchanges are also on her list as she is often sent out to forging lands to secure trade with different races and regions for companies. Roo has a knack for money management and even haggling so shes sought after by high buyers to try and wiggle cheaper prices from merchants or competitors and that often includes learning very detailed cultural customs so she dosn't end up offending clients.
As a secret hobby from time to time she's been contacted for work with Magitek. While she can't make any grand strides in engineering new items she's a master at old tech repair and upkeep. Changes are she can tell you where the item came from, who used it and why it was used.
Books, information or money shes your girl...if you pay her.
