Physiology Expert (5e Feat)
From D&D Wiki
Prerequisites: Wisdom or Intelligence of 13 or higher
You have studied certain kinds of creatures and their physiologies, allowing you to recall information about them and know where to strike them most effectively. When you take this feat, choose two types of creatures: aberration, beast, celestial, dragon, elemental, fey, fiend, giant, monstrosity, plants, humaniod, or undead. You gain the following benefits:
- Your attacks against creatures of the chosen types score a critical hit on a roll of 19 or 20. (If they already do, they score a critical hit on an 18-20. If they already do, they score a critical hit on a 17-20.)
- When you score a critical hit on a creature of the chosen types, add your Wisdom modifier to the damage roll.
- You have advantage on Intelligence checks to recall information about creatures of the chosen types.
You can select this feat multiple times. Each time you do so, you must choose two other types of creatures.
