Blood lust

Blood lust was an enchantment spell that granted a person or creature a heightened state of awareness and increased fortitude for a limited amount of time.

Effects
When this spell was cast, an individual touched by the spell's caster became immune to pain, illness and any fear-like effects. They gained strong feelings of confidence, as if their morale was completely unshakable.

Additionally, the recipient of blood lust gained a keen sense of smell. It was so heightened that it allowed an individual to track another being akin to a scent hound or a skilled outdoorsman.

Components
The casting of blood lust required only verbal and somatic components.
