Had a great time DMing last night. However, there was one frustrating encounter where the players were surprised by a Remhorhaz. The wizard's response was hold monster, and that was pretty much the end of the encounter. The monster was not proficient in any saving throws whatsoever, meaning it needed a natural 18 or higher in the die to break free. My challenging battle had become a game of teeball. What was the real problem here? Was it that the monster had no proficient saves? Or was the real problem spellcasting itself?
