Arc Absorption Shield

The Arc Absorption Shield is an Arc shield carried by some enemies, including Taken Centurions and Colossi. Arc shields are identified by their electricity. Enemy shield types can change in Nightfall strikes and other harder activities: Colossi have Arc shields during the Nightfall strike. Some enemies gain shields in higher-difficulty activities, and some modifiers, such as the Epic modifier, can activate shields on enemies that normally lack them.

Breaking the shield

Arc damage drains the shield faster, and Arc grenades can break it. Deactivating it with an Arc weapon sets off an area explosion that damages nearby enemies. Other weapons can still break it given enough damage, but more slowly. If an enemy takes no damage for a while, the shield recharges quickly. While the Match Game modifier is active, breaking the shield with a non-matching weapon is very difficult, so bring Arc damage.
