Out of Combat: I will tend to Avoid Notice (Stealth+8). I frequently spend time up in rafters or climbing anything that can be climbed, with my Acrobatics+10, Athletics+9 (Assurance 17 result), & Steady Balance feat.
In Combat: Position myself to provide flanking with allies, even if it involves tumbling through an enemy's space. Once in position, I will initiate a Flurry of Blows, followed by casting shield. If I have an action remaining, I will Trip or Grapple (depending on if I think Reflex or Fortitude is the better DC to target) using my Assurance 17.
