Taste of Blood

You touch the freshly spilled blood of a creature that has taken at least 1 point of damage within the last minute. The blood must have been spilled within the last minute, or the spell has no effect. As part of the spell's casting, you can make a melee spell attack against a creature within reach, dealing 1 necrotic damage on a hit. You then taste the blood of the creature, learning one of vital piece of information about it from the list below:

• The creature's highest or lowest ability score
• One immunity, resistance, or vulnerability the creature has, if any
• One disease or poison affecting the creature, if any
• The creature's hit point maximum
• One of the creature's movement speeds
• One of the creature's senses

At Higher Levels. When you reach 5th level, you learn two pieces of information about the creature, three when you reach 11th level, and four when you reach 17th level.
