Borg

You create a sphere around yourself that protects from any harmful attack. This barrier has 5 hit points and when they reach zero the sphere breaks. Then if there’s any remaining damage you must make an Arcana check against a DC equal to half the remaining damage. If you succeed on this check you don’t take anymore damage but if failed you take the remaining damage.

At Higher Levels. When you cast this spell using a spell slot of 2th level or higher, the number of hit points is augmented by 5 for each slot level above 1th.
