So, one of my characters failed successive wisdom saves as the Aboleth sought to dominate him. It took him over, leading to a slow realization as his behavior got more bizarre and the rest of the PCs caught on.
A decent sized tousle and subsequently subduing him in ropes saw him dropped before a priestess of Thor who tried to break the creature's hold. Multiple failed rolls later and he was motionless, the Aboleth's grasp firm. The priestess projected the rest of the 5 person party into the mind/spiritual realm of the afflicted where the group tried to save their friend. They had some buffs, he got to use the Aboleth's stat block, it was chaos and amazing. Printed and painted the mini for the event, they loved it.
They DID succeed in brining him back, defeated the aboleth in its own mind!
