Changes

[[Shielding]] is a [[Boss Modifier]] that may appear on Champions or Elites in Diablo III.

Shielding causes a shielding bubble to appear around the Champion, boss, or boss' minion for a few seconds, every few seconds. The shield grants immunity to all forms of damage and reduces or deflects many [[CC]] effects as well, for the duration of its presence. Monsters can not be hurt in any way while shielded, though they can still be slowed by some rooting effects. (Ones that have a general area of effect like [[Caltrops]], but not specifically targeted ones like [[Entangling Shot]].)

Shielding is identical in function to the (removed) [[Invulnerable Minions]] effect, except that one only appeared on boss minions, and was permanent. Shielding pops in and out on Bosses and Champions, turning on for a few seconds, then vanishing again without warning or any set on/off time.
