You inhale deeply. You have advantage on the next ability check you make that relies on smell, and you can track creatures by scent. When you reach 4th level as a spellcaster in one of the classes above, this spell gives you an increasingly acute ability to identify the source of scents or strange odors. When you reach 5th level, whenever you make an ability check that relies on smell, you can treat a d20 roll of 7 or lower as an 8. At 11th level, a roll of 10 or lower is treated as an 11, and at 17th level a roll of 13 or lower is treated as a 14.
A willing creature you touch gains a preternatural ability to perceive the weaknesses in a creature’s defenses. The first time the creature makes an attack while under the effect of this spell, it makes the attack with advantage. After it makes an attack, the spell ends. This spell augments the creature’s ability to strike at vital points when you reach certain levels. When you reach 5th level, the augmented attack scores a critical hit on a roll of 19 or 20. At 11th level, this range is increased to 18 to 20, and at 17th level, this range becomes 17 to 20.
You utter a bestial, magically-augmented howl that can be heard for 1000 feet. The howl can manifest as any animal call you’ve heard, such as the screech of a hawk or trumpet of an elephant. Choose one creature with whom you are familiar as the recipient: if it can hear your howl, it understands your meaning and can respond in a likewise manner. Creatures other than your recipient that hear the howl and that are under the effects of the comprehend languages spell or similar magic, or that can understand beasts, can understand the howl’s meaning. Otherwise, the howl is unintelligible to creatures that can hear it.
You touch one object that is no larger than 10 feet in any dimension. Until the spell ends, the object sheds bright light in a 20-foot radius and dim light for an additional 20 feet. The light can be colored as you like. Completely covering the object with something opaque blocks the light. The spell ends if you cast it again or dismiss it as an action. If you target an object held or worn by a hostile creature, that creature must succeed on a Dexterity saving throw to avoid the spell.
