Ward

Casting Ward summons a shield either on the caster's self, or someplace in line of sight, if they try to cast Ward out of sight roll disadvantage,

A Ward looks like water that has spilled onto a surface, circular with it's edges splashed but unlike water it is made of glowing blue crystals that emits a smoke that will blind enemies within 2 ft and deals 3d10+5 to any undead within that range unless they have a magic immunity.

Ward will be destroyed after 3 rounds of battle or until struck 1 time

can only be cast the caster's level number of times and requires a short rest to recharge if ward still has at least 1 more use, or long rest if all uses have been used
