Basil's Ominous Octopus Arms

You transform a small continuous flow of water into 3 watery octopus arms. These arms distract attacking enemies, can be used to reduce damage as a reaction, and as an action you can use an arm to grapple an enemy within 10ft of you. when attacked you can choose 1 tentacle that will give disadvantage on an attack and destroys itself in the process. when you suffer damage you can use your reaction to have any number of remaining tentacles to take some of the damage instead. each tentacle can take a total of 10 damage before being destroyed. you can also use an action to grapple and then restrain any creature of medium size or smaller. the grapple and restrain will be against your spell save DC.
