You touch a creature and diminish their sense of feeling, imbuing them with an undead-like resilience. Until the spell ends, the target gains a damage threshold equal to 1d4 + your spellcasting modifier. The target is immune to all nonpsychic damage types, unless the amount of damage from a single attack is equal to or greater than the target's damage threshold, in which case, it takes damage as normal.   In addition, the target's speed is halved, and it has disadvantage on Strength and Dexterity saving throws.
