Improved Brain Extraction

When you make an attack with your tentacles, you may attempt to grapple the target, automatically succeeding if the target is surprised. You make an intelligence or charisma check contested against the targets dexterity check, if you win the target is grappled, otherwise the target may take an attack of opportunity against you.

You can make an intelligence check (DC=targets wisdom) to attempt to extract the brains from a creature you are grappling, automatically succeeding if the target is incapacitated or willing. On a success, you pull extract the targets brain, as with the extract brain trait. Either way the grapple ends. Once you use this ability you can not use it again until you finish a short or long rest.
