We Are One ᴴ

You utter a word that unravels individuality itself. Willing creatures of your choice within a 20-foot-radius Sphere centered on a point you can see within range become united in a single consciousness for the duration. Minds, memories, and instincts merge into perfect oneness—save for two immutable laws: whether or not you are among the linked, only you maintain Concentration on the spell, and no other creature can will for you to lose it; and affected targets gain a Neutral alignment for the duration. 

Unwilling creatures in the area must make a Charisma saving throw. On a failed save, the creature’s mind is drawn into the collective and both gains and grants access to all proficiencies, abilities, and features within the shared consciousness. On a successful save, the creature is Stunned until the end of its next turn. If it succeeds by 5 or more, it is instead Dazed until the end of its next turn. Once joined, a creature cannot leave the collective until the spell ends.

All linked creatures share senses, languages, and memories, gaining unlimited Telepathy with one another. Anything perceived by one is perceived by all. Each participant can use the proficiencies, class features, and spellcasting abilities of any other member, drawing on that creature’s remaining resources. When a linked creature makes a d20 Test, another linked creature can use its Reaction to grant a +5 bonus to that roll.

When the spell ends, each participant must make a DC 20 Wisdom saving throw. On a failed save, the creature gains 2 levels of Exhaustion. On a successful save, it gains 1 level instead.
