True Shield

As a reaction to taking damage, you cause a sphere of magical force to erupt from you, encasing and shielding you from damage. Until the beginning of your next turn, the magical shield absorbs up to 50 damage that you would’ve otherwise taken, including the damage from the attack or spell that triggered the reaction. Spells or other magical effects that deal damage in a line, such as the Lightning Bolt spell, stop completely in front of you if the spell absorbs all of the damage.

When the shield has absorbed all of the damage it can, it shatters.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the amount of damage the shield can absorb increases by 10 for each spell slot level above 5th.
