You can take the Study action to examine a creature as a Bonus Action. You learn the target's creature type and make a DC 15 Intelligence check using a skill from the Examine Specimen table, corresponding to the target's creature type. If you succeed, you learn one of the following pieces of information of your choice about the target: its AC, Immunities, Resistances, or whether it is Bloodied.
Whether you succeed or fail, you can't use this feature again to target that creature or another creature of its specific kind (such as humans or unicorns) until you finish a Short or Long Rest.
