Caving Enthusiast

You have developed an interest in spelunking, making you comfortable in dark and tight spaces. You gain the following benefits:

• Your attack rolls do not have disadvantage while squeezing into a smaller space, nor do attack rolls have advantage against you. You do not have disadvantage on Dexterity saving throws while squeezing.
• Your eyes are accustomed to the dark, granting you 20 feet of darkvision. If you already have darkvision, you instead gain an additional 20 feet of darkvision.
• You gain a climbing speed equal to your walking speed.
• You take 1d4 points of bludgeoning damage for every 10 feet you fall, as opposed to the normal 1d6.
