Guide:Surviving in the Hallow
This means the page will walk you through a specific task, strategy, or enemy/boss fight.
• General review.
The Hallow is the thematic opposite to the evil biomes. Despite its whimsical appearance, it is still a dangerous biome to be in, especially in early Hardmode. It can spread just like the evil biomes, and in comparison to them, most Hallow enemies are fast and deal high contact damage.
Traversing the Hallow may be important, as after defeating the Wall of Flesh, two diagonal strips in a "V" formation will infect the world, one Hallow and the other Corruption/Crimson. Gelatin Crystals can be found underground and used to summon Queen Slime, who can be killed to get valuable loot in early Hardmode, such as Crystal Assassin armor and the Gelatinous Pillion. The Underground Hallow can also provide Souls of Light and Crystal Shards.
Terrain
The terrain consists of whatever biome the Hallow is generated over, converted into Hallowed blocks. This makes the difficulty of traversing the Hallow dependent on the natural terrain it generated over.
Hallowed grass is similar to regular grass, in that it will still grow Mushrooms and Dayblooms. Trees grown on Hallowed grass will provide Pearlwood, which despite providing stronger alternatives to normal wooden equipment, is not of much use even in early Hardmode.
The Pearlstone found in the Hallow, especially underground, requires the same amount of pickaxe power as Ebonstone and Crimstone. It is advisable to have at least a Molten Pickaxe or a Hardmode ore pickaxe to mine through it, since it may take a bit longer to mine compared to regular Stone Blocks. Explosives are also helpful for exploration.
Crystal Shards and 
Gelatin Crystals will quickly start growing on Pearlstone underground, the latter of which will spawn Queen Slime when used in the Hallow. Unlike the Eater of Worlds and Brain of Cthulhu, she will not despawn if the player exits the Hallow, so she can safely be brought to a more open arena.

Recommended gear
It is recommended to have at least 400 health, 200 mana and the best gear available in pre-Hardmode.
- Melee users should at least have
Molten armor. - For rangers,
Necro armor gives the biggest ranged damage bonuses. - Mages have a choice between
Jungle armor and 
Meteor armor. If you have a 
Gray Zapinator, it should preferably be used with the latter. - Summoners can use
Bee armor if they want an extra minion slot, or 
Obsidian armor if they wish to focus on using whips.
Spider armor can quickly be obtained at the beginning of Hardmode.
Weapons
For Melee users
- The
Night's Edge is a strong option for dealing with Hallow enemies.
- Alternatively, the
Breaker Blade deals more damage and knockback, but has less range.
- Alternatively, the
- An
Amarok can be easily obtained early on, has good range and inflicts the 
Frostbite debuff. A 
Hel-Fire is another, slightly weaker option that is acquired similarly. - The
Dark Lance and 
Sunfury are effective weapons that can handle enemies at close range.
For Rangers
- The
Phoenix Blaster or 
Clockwork Assault Rifle are effective guns that are easy to aim with.
- A
Shotgun can also be used, but deals less damage at longer distances.
- A
- The
Molten Fury is a useful bow, and can be replaced with any Hardmode ore repeater later. - The
Toxikarp must be fished up in the Corruption, but does not use ammunition, has decent range and inflicts the 
Poisoned debuff.
For Mages
- For single target damage, the
Flamelash or 
Flower of Fire are great options. - The
Laser Rifle or 
Demon Scythe are useful for crowd control.
For Summoners
- The
Spider Staff can quickly be obtained early on, and is the most reliable minion available. They also inflict the 
Acid Venom debuff.
- Alternatively,
Abigail's Flower gains a damage buff in Hardmode, but should be used with the Firecracker.
- Alternatively,
- The
Spinal Tap and 
Firecracker are the best whips the player can obtain. - The
Queen Spider Staff is the only sentry that becomes available in early Hardmode, and inflicts the Acid Venom debuff.
- If you have not obtained it yet, but have defeated the Tier 1 Old One's Army, the
Ballista Rod can also be used.
- If you have not obtained it yet, but have defeated the Tier 1 Old One's Army, the
Accessories
- Any Emblem dropped by the Wall of Flesh (
Warrior, 
Ranger, 
Sorcerer, 
Summoner) should be used. 
Lightning Boots or its upgrades, or 
Amphibian Boots are very useful for mobility.
Wings are always useful to have in Hardmode. If you do not have any yet, a Horseshoe balloon can be used instead.- If you are playing on Expert Mode or higher difficulties, the
Worm Scarf will reduce any damage taken. Alternatively, the 
Brain of Confusion can prevent damage altogether, but has a cooldown. - Melee users and summoners will benefit from having the
Power Glove. - The
Magic Quiver is useful for rangers focusing on bows or repeaters, but is a rare drop from Skeleton Archers. 
Celestial Cuffs can be used by mages to quickly recover mana. Alternatively, if you do not mind the 
Mana Sickness debuff, the 
Mana Flower can be used.- Summoners should use the
Pygmy Necklace for an extra minion slot.
Other tips
- Unlike the Corruption or Crimson, town NPCs can live in the Hallow without leaving. In fact, it is a good idea to have your base Hallowed, as this will stop the evil biomes from spreading towards it.
- NPCs that are happy enough will also sell Hallow Pylons, which are useful for fast travel.
- The Hallow cannot spread through Mud Blocks, and as such there is no Hallowed Jungle grass, possibly making it more difficult to farm surface Hallow enemies. If the Hallow strip of the Hardmode "V" formation happens to hit the Jungle, it may be necessary to buy Hallowed Seeds from the Dryad in order to spread the Hallow somewhere else.
- The
Crystal Serpent is a great weapon that can easily be obtained at the beginning of Hardmode. It can very rarely be fished up in the Hallow in any layer.
Surface Hallow
None of the surface Hallow enemies can fly, so a good strategy for dealing with them is to attack them from a distance, using Rope and Platforms to locate to a spot that they cannot reach. Some additional measures, such as boxing yourself in, may need to be taken at night due to Gastropods, however.
Pixies can occasionally inflict the 
Silenced and 
Slow debuffs upon contact. Despite appearing to fly, they actually only hover through terrain. While they aren't too big of a threat on their own, multiple of them can end up overwhelming the player, especially at night.
Unicorns are very fast, along with having high health and knockback resistance. They can easily catch an unprepared player off guard, but can only jump up to a height of 7 blocks. A long-range weapon like a gun or yoyo can be used to easily kill them.
Gastropods spawn during the night. They are slow, but common with high health and defense, and can also shoot high-velocity lasers to hit you from afar. While they are the most threatening of the surface Hallow enemies, their laser attack gets cancelled out when hit, meaning a fast weapon that attacks continuously can be used to immobilize them.
- Alternatively, Gastropods are considered slimes, so the Expert Mode-exclusive
Royal Gel will make them completely harmless.
- Alternatively, Gastropods are considered slimes, so the Expert Mode-exclusive
All three surface Hallow enemies have one guaranteed drop along with a few rare drops. Pixies drop 
Pixie Dust, and rarely drop the 
Fast Clock and 
Megaphone. Unicorns drop 
Unicorn Horns and rarely the valuable 
Blessed Apple, while Gastropods drop 
Gel and rarely 
Chocolate Chip Cookies.
Consider using bombs to collect large amounts of Pearlstone. Pearlstone can be used to make an artificial Hallow biome or farm Hallow enemies later on.
Once Plantera has been defeated, 
Prismatic Lacewings start appearing at night, and disappear during the day. These are harmless critters, but players should be careful when approaching them, as killing a Lacewing will summon the Empress of Light. She is a difficult boss that will likely require post-Golem gear, but will drop valuable loot when killed, such as powerful weapons and 
Empress Wings. She can be seen as a timed boss fight, however, as she will enrage during the day, causing her attacks to instantly kill you.
Just like most other critters, the Prismatic Lacewing can be caught with a Bug Net for future use. Players can also keep a Guide to Critter Companionship in their inventory for an easier time catching Lacewings, or if you simply do not want to fight the Empress of Light yet.
For a specific guide on the Empress of Light herself, consider checking out Guide:Empress of Light strategies for more information on that fight.
Underground Hallow
Most of the value in the Hallow lies in the cavern layer, within the Hallowed portion of the Hardmode V spread. Each enemy here has a 1/5 (20%) / 9/25 (36%) chance of dropping a 
Soul of Light, a valuable crafting material.
If the player is willing to take a bit more time, an enemy farm will provide a safe and efficient way of getting the valuable enemy drops from the Underground Hallow.
There are many new enemies for you to deal with: The Illuminant Bat, Chaos Elemental, Illuminant Slime, Enchanted Sword and very rarely the Hallowed Mimic.
Illuminant Bats are comparable to Giant Bats: They have higher stats, but in return do not inflict the 
Confused debuff (or Feral Bite in Expert Mode). Similarly, any long-ranged weapon will work on the Illuminant Bat, such as boomerangs or bows.
Chaos Elementals are fast and unpredictable, occasionally teleporting if they can't reach the player. It is recommended to carve a more open area to make them easier to deal with. They are notable as they very rarely drop the 
Rod of Discord, a powerful tool.
Illuminant Slimes act just like a regular slime. Due to the limited mobility of slimes, they are generally less dangerous than other enemies.
Enchanted Swords are an uncommon enemy that can move through blocks and can inflict 
Cursed on hit. This makes them potentially the most dangerous enemy to be hit by, but due to low knockback resistance and tendency to stop moving when hit, you can knock them away with any weapon that can attack through blocks, such as whips or the Night's Edge. They are very easy to spot.
Hallowed Mimics are the Biome Mimic of the Hallow. They are passive until damaged by the player, but have immense health, damage, and the ability to move through blocks. Their loot is very valuable, and there are a number of ways to defeat them, such as with decent open space, but depending on the situation you likely want to leave them alone. You can craft 
Keys of Light later to summon them manually in a more open area.
Alongside these enemies, pink Pigrons start spawning in hallowed Ice biomes, while four new enemies can appear in a hallowed Desert: Light Mummies on the surface, along with Light Lamias and Dreamer Ghouls underground. Crystal Threshers can appear on the surface during a Sandstorm.
Pigrons can become nearly invisible and appear when they are about to attack you, but make audible growls as they approach. Any weapon that can attack through blocks can be used to kill them. Pigrons may drop valuable Bacon.
Light Mummies will start running faster once reduced to 50% health or lower, but otherwise behave similarly to Zombies. They can drop 
Light Shards, which can be used to craft the Dao of Pow or the Sky Fracture.
Light Lamias aggressively chase you, attempting to deal contact damage. It is best to carve out a larger area in the Underground Desert, preferably in pre-Hardmode, so that they are less likely to reach you.
Dreamer Ghouls will inflict the Confused debuff upon contact, making them a bit more threatening in close quarters. Any long-range weapon can be used to kill them. They may drop Light Shards.
Crystal Threshers "swim" inside sand blocks and jump out to deal contact damage, although they cannot swim through any other blocks. You can take advantage of this by baiting them into jumping out of the sand and into non-sand blocks where they become more vulnerable to attack. The best way to deal with them, however, is to place platforms above a height that they cannot reach, and attack from above with any weapon that shoots projectiles. They can only jump up to a height of 16 blocks for reference. Crystal Threshers can drop Light Shards and Shark Fins.
