Altar

Altar may refer to:
 * The Hall of Storms is sometimes called Altar.
 * When a team captures both shrines on Dragon Shire, it unlocks the Dragon Altar located at the middle of the map. Once captured, the altar unlocks for that team only, and a hero may channel it for several seconds, during which he can be interrupted by taking damage or moving. If successful, the hero transforms into the Dragon Knight which lasts for a couple of minutes.
 * On Towers of Doom both Cores are protected by a barrier that cannot be attacked by Heroes. Periodically Altars will rise across the battlefield. Activate them to have your Bell Towers fire upon the enemy’s Core.
 * On Tomb of the Spider Queen minions and Heroes drop gems upon death. Whichever team turns in enough gems on the Spider Queen' Altars first will unleash the Webweavers to destroy their enemy's defenses.
