This magnificent platinum shield seems to pulse with an air of invincibility.

When you activate a shield that has this property, you can avoid injury by manipulating time. You are invulnerable to all attacks, spells, and powers (both harmful and helpful), beginning immediately after you activate the effect and ending at the end of your next turn.
The time buttress property functions once per day.

Prerequisites: Craft Magic Arms and Armor, temporal stasis or timeless body (EPH 138).
Cost to Create: 12,500 gp (plus 150 gp for base item), 1000 XP, 25 days.
