Should you spare Xanthe in The Blood of Dawnwalker?

When deciding whether to spare Xanthe in Blood of Dawnwalker, one must consider the consequences. Xanthe is an evil ancient vampire who has kidnapped and killed innocent women, but she may be using Brencis as a convenient tool. Sparring with her will result in a less challenging castle assault, as you won't have to fight Rebel Wolves or Blood Guard enemies.

Additionally, you won't have to endure the nightmare sequence that comes with killing her. However, the real benefit of allying with Xanthe is the Blood Surge ability, which unlocks upon drinking her blood. This ability allows you to perform a powerful melee attack that can be useful in combat. Alternatively, killing Xanthe results in additional dilemmas, such as deciding Chariklea's fate and managing the dark magic that keeps her alive.

Ultimately, sparing Xanthe offers advantages in terms of difficulty reduction and granting a new ability, but the moral implications and potential long-term consequences must be weighed before making a decision.
