Unshakable

Upon recieving damage from a nonmagical weapon or any sort of elemental magic, you suppress uncoming damage from similar attacks through intense focus. Until your next turn, you gain resistance to bludgeoning, piercing, and slashing damage from a nonmagical weapon, as well as resistance to elemental (fire, cold, lightning, thunder) damage. You also become immune to several conditions that would interrupt your flow, such as being stunned or paralyzed. This immunity also lasts until your next turn. 

If you already have a condition that you would otherwise be immune to thanks to the spell, this spell clears it up. Any other condition you would not be immune from remains.
