Be it during a fight or life in general, moral compass means little to Tabriss. If you don’t want a person harmed, you had better specify. General terms mean nothing to him as Tabriss only deals in specifics. If the rules of a duel say you can’t shoot before the count of three? A grenade over the shoulder is fair game, then. Tell Tabriss to stop someone at all costs, well, you better not be concerned if they’re brought back dead or alive.

When Tabriss does things, he makes sure everything is done correctly, no matter how long it takes. This means there are frequent delays in Tabriss's work, but it's usually done right, at least.

Tabriss considers his work to be the most important aspect of his life. This borderline obsessions with the "job" leaves little room for any kind of personal or social life, making it difficult for Tabriss to relax and enjoy spending time with others. he excels in activities that relate to their work, but the idea of work-life balance is an altogether abstract concept.

Tabriss is extremely cocksure and headstrong. Possessing a keen wit and exceptional level of intelligence, Tabriss will often use his superior intellect to humiliate lesser minds. Basically, he is kind of a jerk, and that can sometimes get Tabriss in a bit of trouble.

Sometimes the only way to prepare for the worst is to always expect it. Tabriss takes this philosophy one step further by never leaving home without accounting for every possible scenario he might expect to encounter. Tabriss tends to always have the right tool or item for a situation and has a habit of quietly and almost smugly presenting solutions before anyone even recognizes there is a problem. This foresight is far from infallible, however, and he often finds himself at a loss in situations that go beyond what he could have imagined. While incredibly practical and often a life-saver in a pinch, his perpetually pessimistic outlook on daily life can be a bit draining on more optimistic-inclined companions.

Tabriss vastly prefers ranged combat, taking every opportunity to use skills and Force Powers to disengage from melee and instead fight at range, so much so that he has become competent at staying out of melee in the first place.
