Solar Eclipse

A  is an event that occurs periodically in the daytime. It has a 1/30 (3.33%) chance of appearing instead of a normal day. A solar eclipse starts at sunrise and ends when night begins (lasting for 15 minutes). This is similar to the Blood Moon, but Solar Eclipses can only occur in Hard Mode.

A Solar Eclipse can happen at any time '''after the player has defeated the  Wall of Flesh and has beaten one of the mechanical bosses. '''When a solar eclipse happens, Halloween themed mobs are spawned (refer to the chart below). They are also a great source of money; a skilled player can earn upwards of 2 Platinum Coins if you fight enemies for the entire event.

The monsters that spawn have a chance to drop the Broken Hero Sword which is a material vital to the late-game melee-weapon user, due to it being used to craft the True Excalibur, True Night's Edge and Terra Blade.right|300px

Fighting
It is recommended to get away from your house so that the mobs do not go after your NPCs. Get to a flat area and acquire a weapon that can attack multiple enemies, such as the Paladin's Hammer or the Piranha Gun. The mobs will start to rush at you in lines, and with your weapon you can quickly finish off the entire line of enemies with a few strokes of your weapon.

Another strategy is to build a lava-pit at either side of your home and a loot-corridor underneath. This way you just have to sit out the solar eclipse, watching as hordes of monsters die in your lava-pits and loot as you walk underneath.

If you need to farm monsters its a good way to build a platform and shoot monsters from there. But if you use this strategy watch out for Vampires since they can fly. For this strategy excellent weapons are the Inferno Fork and Piranha Gun.

Escape
Escaping to the underground stops solar eclipse monsters from spawning. If you need to have a break from the solar eclipse, or the monsters are overpowering you, simply run away into a cave. Space is also an option, but Harpies and Wyverns are affected the blood moon, therefore they will spawn at a higher frequency.

Alternatively, a sufficient quantity (~50 blocks) of Meteorite nearby will replace Solar Eclipse monsters with normal Meteor Heads.

Bugs

 * If you are halfway through an eclipse and you Save & Exit and then re-open the world, the eclipse will be over and it will be a normal day.
 * Sometimes, the eclipse event can keep going in any world until dawn.

Trivia

 * An Eclipse is possibly the event that rewards most money in comparison to other events like the Blood Moon or the Goblin Army.
 * In spite of the moon technically being in front of the sun, this event will not grant the bonuses of a Moon Stone or trigger a werewolf transformation.
