Sith determination and Zeltron empathy make for curious bedfellows. Erinyes respects a willingness to "do what has to be done", but has no patience for those who inflict suffering on other people for no reason.

Erinyes' sudden transition from warrior to diplomat and PR manager has forced her to rethink her approach to her duties. She's becoming more comfortable with employing sweet words, half-truths, and "certain points of view", but she hasn't given up on her old ways. Goading a counterpart into doing something out of spite and leveraging her knowledge of Dun Möch to pick apart a diplomatic opponent's weaknesses are both fair game in her mind.

Like most Zeltrons, Erinyes is quick to develop intense attractions, and is reluctant to make the subjects of her affections suffer. She's easily distracted by humanoid females with pretty faces and/or well-sculpted bodies, and often acts in a flirtatious manner towards them, which frequently leads to putting her foot in her mouth. When interacting with those she finds attractive, Erinyes typically demurs to or goes easy on them in a bid to win their approval, except in the most dangerous of situations.

Erinyes never does—or says—anything halfway. She is well accustomed to speaking her mind to anyone if she thinks she can get away with it, regardless of their relative positions, up to and including fellow Elders and even Grand Masters of the Brotherhood. The only opinions she truly values are her own, unless they come from someone who can make her follow them by force. It's even common for her to use her forthrightness as a battle tactic, throwing opponents mentally off-balance with the most outrageous, outlandish, offensive, and downright unbelievable commentary she can.

Erinyes' combat style focuses overwhelmingly on offence. She strikes out with words through Dun Möch even before her opponents draw their weapons. Though she carries two lightsabers, she typically only uses one; instead, she amplifies Juyo's relentless assault by switching hands and grips to strike from any angle, while using Force-granted speed and mastery of Tràkata to bypass her opponents' parries. If an opponent forces her to remain at a distance, she employs either a blaster, the pistol mode of her lightsaber, or Telekinetic Combat. On defence, Erinyes heavily favours mobility, and draws on the Force to compensate for her lack of physical endurance (or more rarely, to shield herself from attacks she simply can't dodge). Like many Force users, her fighting style relies on being able to access those powers, and her effectiveness in combat suffers when that option isn't available.

Erinyes enjoys fighting the same way she enjoys dancing or other physical activities. When faced with an opponent who provides an interesting challenge in battle, she’ll take steps to prolong the battle, such as letting a weary opponent rest or using the “training saber” phase of her main-hand lightsaber when fighting opponents who don’t possess lightsaber-resistant weapons. Sometimes this leads her to prolonging fights unnecessarily, a risky tactic when her fighting style requires a great deal of energy to maintain.
