Elemental Barrier [two-actions] Focus 4

A barrier of protective elemental energy appears around the target, bolstering their defense. Select an elemental trait: air, earth, fire, metal, water, or wood. Elemental barrier gains the trait you chose. The target gets a +1 circumstance bonus to AC. While the spell is in effect, the target can use the Shield Block reaction as if the elemental barrier was a raised shield.

The barrier has Hardness 6 and 40 HP. It has Resistance 2 to one damage type based on the chosen trait: electricity or sonic for air, bludgeoning or piercing for earth, acid or slashing for metal, fire for fire, cold for water, or poison for wood. Unlike a normal Shield Block, you can use the spell's reaction against spells with the chosen elemental trait cast against the creature.
