Grell's Prowess

You have developed traits similar to those possessed by a grell, granting you the following benefits:

• You gain proficiency in Stealth. If you are already proficient in Stealth you gain expertise in it.
• You gain resistance to lightning damage.
• You gain blindsight out to a range of 60 feet.
• Once per turn, when you hit a creature with a weapon attack, you can force the target to succeed on a Constitution saving throw (DC 8 + your proficiency bonus + your Constitution modifier) or be poisoned for 1 minute. The poisoned target is paralyzed, and it can repeat the saving throw at the end of each of its turns, ending the effect on a success. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
