Stella appears only at the Fort once the Laurifer Gladiator quest is begun.
She has a number of special perks that increase her effectiveness in unarmed combat. In combat with the player character, she can easily cripple limbs in one or two hits, making her a dangerous opponent.
Stella has all three ranks of the Iron Fist perk, despite it being a Fallout 3 perk and unavailable in Fallout: New Vegas.
Killing Stella does not lower the player character's reputation with the NCR.
Upon death, Legion soldiers at the Fort will be impressed and comment on her death.
Killing Stella with the machete counts for the Gun Runners' ArsenalchallengeArmed For Bear. A machete is always equipped for the arena, so one will gain a point towards this challenge unless the machete is unequipped and one kills her with their bare fists.
↑The Courier: "I'd like to fight in the arena." Otho: "I have a dangerous one for you - an NCR Ranger by the name of Stella. We got lucky, since we rarely capture Rangers alive. Even though she's a woman, she's killed every man who's faced her in the arena, even one of the elite Centurions. With her bare hands." (Otho's dialogue)
