True Shield

You summon a sphere of force energy that protect you from being harmed. Until the end of your next turn, you gain 50 temporary Hit Points that absorbs damage from attacks, spells and damaging effects (including the triggering damage). Line effects and spells, such as Lightning Bolt and some dragon's breath, stop completely at the sphere if its damage is entirely absorbed. Additionally, you take no damage from the Magic Missile spell.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the amount of temporary Hit Points you gain increases by 10 for each slot level above 5th
