Almost got natick-ed on MEDIC/the 2nd portion of the long word, but was able to suss it based on the absurd amount of prefixes. However, you might want to check the clue for OGRE, as it implies a plural. Fun puzzle overall!
One time I had an entire (mini) crossword as a Caesar cipher—sometimes I want to focus on doing something groundbreaking rather than providing the best experience ;). In any case, thanks for alerting me to the OGRE clue, which I fixed!
