Mask: Sea Urchin

While wearing this mask, you can use a bonus action and expend a use of your Bardic Inspiration, rolling a Bardic Inspiration die to heal yourself for a number of hit points equal to the number rolled plus half your bard level (rounded up). Additionally, you can use an action to attempt to immobilize a creature you can see within 30 feet of you, injecting it with magical toxins. The target must succeed on a Constitution saving throw or become restrained for 1 minute. At the end of each of its turns, the target can repeat the saving throw, ending the effect on itself on a success. You can use this ability a number of times equal to your proficiency bonus, and you regain all expended uses of it when you finish a long rest.
