If the tail keeps missing you like it always does with me, I do it on PlayStation, just so you know because the controls may be different. Keep holding up your shield even after she’s grabbed you, it’s best to already have the containment chamber on hand aswell. Reaper pheromone glands are really easy to get, use a high melee pump shotgun on the low levels. Be out of their impregnating range though, because then you would need an abortion.
