Terrariais a sandbox-style game that challenges players to explore. The game has an extensive network of biomes and caves to investigate. There are also a number of creatures for players to find while they’re out and about, and many of them are hostile.
Combat is a big part ofTerraria. From squishy bats to the intimidating Wall of Flesh, the game has a long list of enemies for players to encounter. This includes many powerful bosses and side bosses, which are hostile, powerful creatures. They drop important items which players need to progress in their games. Side bosses are one type of boss inTerraria. Despite their name, they’re just aschallenging as the game’s other bosses; the only real difference is that most side bosses only spawn during special events. Here’s how to beat each and every one of them.

Spooky Armor or Tiki Armor
Shroomite Armor
Betsy is a Wyvern that spawns in at Tier three of the Old One’s Army event. She appears during the seventh wave. Players can summon this event using an Eternia Crystal, whichThe Tavernkeep will sellafter the Golem has been defeated.
Betsy behaves similarly to Duke Fishron. Move quickly to avoid her attacks and avoid being backed into a corner. If possible, target the Etherian Wyverns that appear alongside the boss. Many of Betsy’s attacks are fire based. Try to drink an Obsidian Skin Potion before summoning her. This will keep her from inflicting the On Fire! debuff.

Necro Armor
The Dark Mage spawns during the Old One’s Army event. It appears in the fifth wave at Tier one, and in early waves at Tier three. The Dark Mage floats above the ground throughout the fight. It can throw dark energy,heal the player’s enemies, and summon Old One’s Skeletons.
Defeating the Dark Mage can be tedious. It appears in the final wave of its event, andTerrariaplayers will have totake down lots of smaller enemiesbefore they encounter it. Be sure to stock up on Healing Potions beforehand.

Everscream is a hard mode boss that appears duringTerraria’sFrost Moon event. It is an evergreen tree that attacks the player with pine needles and ornaments. Players can summon the Frost Moon by using a Naughty Present at nighttime.
This boss behaves similarly to Mourning Wood. Most of its attacks are avoidable from a distance, sousing weapons with a longer rangeis a good tactic. Players may also want to build platforms to move between.

Titanium Armor
Named after the mythical ghost ship, the Flying Dutchman is a boss fromTerraria’sPirate Invasion event. Players cantrigger this event by using a Pirate Map. It also might occur randomly.
The Flying Dutchman also has four powerful cannons, which players must destroy before the Flying Dutchman can be defeated. It also has the ability to spawn pirates to attack the player. Because of this, it’s best touse weapons that can target multiple enemies.

The Ice Queen’s attacks can cause the Chilled and/or the Frozen debuffs, which will slow down or stop players' movement. If possible,drink a Warmth potion before fighting her. It’s also a good idea to use equipment with movement enhancement.
During the fight, the Ice Queen will use a Twirl attack. She’ll spin and unleash a barrage of Frost Shards, but will otherwise stay in the same place. This is a good time for players to attack her. Just be sure to avoid the Shards –using wings can help with this.

The Martian Saucer is a boss from the Martian Madness event. This event is triggered if a player encounters a Martian Probe and lets it escape. It will only occurif the Golem has been defeated.
The Martian Saucer is modeled after an alien’s UFO. It flies above the player and targets them with one of three attacks. It will shoot lasers and then missiles at the player. The lasers are easy to dodge, but the missiles will follow players as they move. Dodge these by moving in ways that aim them at the ground. The Martian Saucer’s final attack is a death ray. Fly oruse a grappling hook to get abovethe boss.

Shroomite Armor with Forbidden Treads
Mourning Wood is a tree-themed boss that spawns duringTerraria’sPumpkin Moon, and behaves similarly to the boss Everscream. However, Mourning Wood’s attacks are fire related. It is immune to lava and the On Fire! debuff.
One of Mourning Wood’s main attacks is to shoot piercing Greek Fire at players. If possible, lure Mourning Wood intoa shallow body of waterand attack it from a distance. Its attacks will be unable to reach players.

Bee or Obsidian Armor
The Ogre is a boss fromTerraria’sOld One’s Army event. It is a slow moving creature with a dangerous club, and it appears in the final wave of Tier two and in the fifth and sixth waves at Tier three.

The Ogre has three ways of attacking. Firstly, a single hit from its club inflicts a major amount of damage. Avoid this by keeping some distance from the Ogre. Its jumps will cause a shockwave to knock back anddamage players within range. Finally, the Ogre will also throw a ball of Ogre Spit at players. Using a flying mount will negate the Oozed debuff that this attack inflicts.
The Pumpking is the final boss ofTerraria’sPumpkin Moon event. Players caninitiate a Pumpkin Moon eventby using a Pumpkin Medallion.

The Pumpking will try to attack players from above. Its most dangerous attack involves a Flame Scythe projectile. Although its attacks are fast, the Pumpking itself is slow, which is its biggest disadvantage in combat. Playerswill be able to avoid itby moving in large circles. Just be careful not to get backed into a corner.
Players will encounter Santa-NK1 during the Frost Moon event. It will attack players with spiked balls, missiles, and a chain gun. It will also drop harmful presents that will damage the player.
Santa-NK1’s attacks can deal a lot of damage. Be especially careful to avoid the spiked balls, as these can be deadly. Players will want to use longer-range weapons to attack Santa-NK1. If possible, equip wings to help evade attacks.
