Delve

You place a hand on the target of this spell and focus to extend your senses within their body. For the duration, you can take the Magic Action to roll a  +5 Medicine check to sense the health status of the target creature, including pain and ailments, external and internal injuries, presence of diseases, levels of Exhaustion, any mental or psychic Impairments or effects, presence of foreign objects or outside influence within the body, and the presence and effects of Poisons or Toxins. You may only target one creature at a time, but you may target multiple creatures more than once for the duration of the spell, until it ends. If cast on an unwilling creature that creature must make a Constitution Saving Throw, on a Fail the spell Succeeds, on a Success the spell Fails with no effect, however if cast as an Action during Combat the Spell Slot used is not Expended. DC equals your Spell Save DC. 

The spell is blocked by 1 foot of stone, dirt, or wood; 1 inch of metal; or a thin sheet of lead.
