Phantasmal Deathray

For more elaborate strategies on defeating the Moon Lord and learning about his abilities, including Weapon and Arena recommendations, see Guide:Moon Lord strategies.

The Phantasmal Deathray is a devastating laser beam fired by Terraria's final boss, the Moon Lord. The Deathray emerges from the central eye of the Moon Lord as a thick line that reaches beyond the edges of the targeted player's screen, and will sweep the area, covering most of the screen in its path. If his target is to his left, it sweeps clockwise. If they're to his right, it sweep counter-clockwise. The central eye takes at least 2 seconds to charge the attack and will remain open for a further 2 seconds before closing, accommodated by two phantasmal bolts prior and after. The Phantasmal Deathray deals incredibly high damage: 150 in Normal Mode, in Expert Mode, and  in Master Mode.

The True Eyes of Cthulhu can each fire their own version of the Phantasmal Deathreay, however theirs are thinner, deal half the damage, and have much less range.

Tips



 * It is possible to avoid the Deathray by staying close to the Moon Lord's head, and moving up and around the central eye as it fires the ray. The ray does not sweep as quickly when nearby its origin point, due to the nature of rotational movement, so being as close to its origin as possible makes it easier to maneuver around.
 * The Mechanical Cart's speed allows the player to outrange the laser, as well as the Eyes' own.
 * The Rod of Discord is a significantly easier option as it allows the player to instantly warp past the laser.
 * The ray doesn't go through solid blocks in the, allowing the player to build overhead cover to shield themselves from it.
 * The beam can pass through blocks in the, however, meaning the player should not try to shield themselves.
