Arcane shield

Create a 5x5 ft magical stationary shield, it is immune to poison damage and psychic damage. When creating it, you can determine if it has a 2ft long horizontal or 3ft long vertical arrow slit on it. The arrow slit is wide enough to look through easily and it is also wide enough for a spear or an arrow to go through. The shield is light enough for an average person to carry it with ease but it won't make a good shield to wield in your hand because of its size.

The hp the shield has is defined by the caster's hp + caster's level. If its hp goes down to 0 or below 0, it will disappear instantly

If the mending spell is cast on it, heals 1d6 hp
