Defensive Mindweb

Psychically link the minds of you and your allies, sharing your mentals strengths against pyschic assault. For the duration, everyone in the mindweb has resistance to psychic damage. Additionally, when the target of a spell or ability that requires a Charisma, Intelligence, or Wisdom saving throw, everyone in the mindweb uses the highest creature's modifier for that ability score as their own. 

When a creature in the mindweb takes damage, they must succeed on a Wisdom saving throw to remain in the mindweb. If they move more than 100 feet away once the initial link is established, they are removed from the mindweb.
