Solar Eclipse



A Solar Eclipse is an event that occurs rarely in Hardmode after at least one of the Mechanical Bosses has been defeated. It is announced at the beginning of a day with the message, "A solar eclipse is happening!", lasting from sunrise to sunset. Light will be only slightly brighter than at night, the moon is visible in front of the sun. A Solar Eclipse has a 1 in 25 chance of occurring on any particular day (for comparison, the Blood Moon has a 1 in 10 chance each night).

A Solar Eclipse is akin to a daytime Hardmode version of a Blood Moon. Enemy spawn rates are very high even near NPCs. It is different in its rarity, and in that the event takes an entire day rather than the shorter night period (15 minutes vs. the Blood Moon's 9 minutes). It also spawns more of its own unique enemies, which can each drop unique rare items: Death Sickle, Eye Spring, Broken Hero Sword, Moon Stone, and Broken Bat Wing.

The event only affects the surface layer, and can be avoided by burrowing well into the underground layer or below.

Strategy

 * All of these have high HP and high damage, and some of them have special features that make fighting them extremely hard. It is recommended to treat this event as a Boss fight mixed with an Invasion, since there will be large numbers of very tough and unusually agile enemies, most of which are resistant to knockback.
 * Every enemy but the Reapers and Vampires use standard Fighter AI, (and even the same jump range as basic Zombies and Goblins,) and will walk into pits just like any other zombie. Lava pit traps will destroy the whole invasion force but the reapers.  Hence, the easiest way to nullify most of the threat is to dig a simple tunnel underneath a small lava pit on some leveled terrain. That allows players to simply focus on fighting the Reapers alone, (which are rare enough that you rarely fight more than one at a time,) while collecting all the drops.
 * More advanced arenas involve putting the player in a floating room above where the Reapers can reach, with lava pits and traps set to Timers to kill off mobs, and a teleporter or two to get to loot-collection points or out of the safe room. Even without traps, a weapon that attacks through blocks, (Inferno Fork, Mushroom Spear, Nettle Burst, etc.,) allows players to ignore most of the threats.
 * If the player wishes to fight the Solar Eclipse enemies directly, it is best to fight in prepared terrain. Flat terrain is good against most of the enemies, forcing enemies to come at only two angles, but many players recommend a pair of mounds on either side of the player to cut down on the distance at which the Eyezor can attack.
 * The enemies have a relatively large amount of health, defense, and offense, so use top-tier weapons specifically good against crowds. This basically means either high-rate-of-fire, or piercing combined with good knockback. (Eyezors don't suffer knockback, however.)  This includes weapons like the Flamethrower, Leaf Blower, Chlorophyte Shotbow, Rainbow Gun, Paladin's Hammer, among others.
 * As with most fights challenging enough for a player to want to prepare for, a Heart Statue (and Star Statue for magic-users) set to multiple timers, a Campfire, and a Heart Lantern all allow greater health regeneration. (Add a Crystal Ball as well for magic-users.)
 * Like the Blood Moon, a Water Candle and Battle Potion ups the spawn rate of enemies even higher. If you are farming enemies for the top-tier Death Sickle or Broken Hero Sword drops, these will indirectly help increase the rate of drops.
 * The high rate of enemy spawns makes getting a Dungeon Key Mold relatively more common. In building an arena, a player might swap out the tiles they surround themselves with in order to get a chance to spawn different molds.

Trivia

 * It is not a total Solar Eclipse. It is actually an annular ring eclipse, when the moon is not quite close enough in its orbit to cover the entire sun. The moon has a elliptical orbit around the Earth, being closer or farther in its orbit at times. The moon also revolves around Earth at a 5 degree plane, where as if it was at a 0 degree plane, you would have a Solar Eclipse every lunar month.
 * The music that plays during an eclipse is the 'Terraria 1.2 Update - Music Spoiler' that Red uploaded to his Youtube Channel 'Demilogic' (http://www.youtube.com/user/demilogic?feature=watch) on August 10, 2013.
 * Solar eclipses only last for a few minutes in real life. A day-long solar eclipse would be impossible in real life, as well as the frequency of the event occurring.
 * While in Terraria a solar eclipse can happen any day, when in real life they can happen only during a new moon.
