Sea Sight

Your eyes are accustomed to penetrating the murk of the sea and the creatures lurking in it.
Prerequisite: Perception proficiency, swim speed.
• You can see out to double the normal range in the water. If you have darkvision, the range of that darkvision is also doubled underwater.
• When your attack misses a creature in the water due to obscurement, you can reroll that attack once.
• You have advantage on Wisdom (Perception) rolls when underwater.
