Bump in the Night

Whether it is in the pages of forlorn books or by the telling of tall tales around campfires, you have come to be quite the fanatic of horrors. Well, scary stories at least.  Thanks to your delightful knowledge of such awful tales, you find yourself better aware of the monsters you may face. 

Choose three monster types, except humanoid, to gain the following benefits:

- You are immune to the surprised condition by those creature types.
- You may add your proficiency modifier to saving throws against those creature types. If you are already proficient in a saving throw, you still add the proficiency modifier again. 
- You use your bonus action to predict the monster's next action to alert your team. Roll a d20 + proficiency modifier + investigation or perception. DM determines how high a roll allows you to predict accurately.
