An invisible barrier of magical force appears and protects you or a creature of your choice within range, granting it a +1 bonus to AC for the duration, including against the triggering attack, and the target is resistant to force damage.
The Nesting Shield spell’s effects stack with any other Shield spell’s effects. The maximum number of active Nesting Shields you are capable of casting that a target may benefit from is limited to ½ your (Proficiency Bonus + Spellcasting Ability Bonus) rounded up. Each layer of a Nesting Shield resists force damage, reducing the force damage in half rounded down at each layer to a minimum of 0 force damage. If cast multiple times on a target, the Nesting Shield Spells are automagically self-arranged in layers in order of longest duration being innermost and shortest duration being exterior. Nesting Shield Spells cast on a target with any other Shield Spell will always be inside of the other Shield Spell.
