Betsy, the fearsome dragon mini-boss, makes her grand entrance on Wave 7 of the Old One’s Army event, acting as the final challenge of this multistage invasion. Defeating her is crucial to successfully completing the event’s Tier 3.

Understanding Betsy and the Old One’s Army

The Old One’s Army is a crossover event with Dungeon Defenders 2, integrated into Terraria. To encounter Betsy, you must first trigger this event. The event comes in different tiers, and Betsy appears specifically in Tier 3, which is a Hardmode, post-Golem challenge. This means you must defeat the Golem boss in the Jungle Temple before you can even attempt to summon Betsy.

Initiating the Old One’s Army

To begin the Old One’s Army, follow these steps:

Acquire an Eternia Crystal and an Eternia Crystal Stand: These are both purchased from the Tavernkeep NPC, who appears after you have defeated the Eater of Worlds or Brain of Cthulhu.
Find a suitable location: The event requires a flat, open area for enemies to spawn.
Place the Eternia Crystal Stand: Position the stand in your chosen arena.
Activate the Eternia Crystal: Interact with the stand while holding the Eternia Crystal to start the event.

Once initiated, waves of enemies will begin to attack from both sides, and you must defend the Eternia Crystal. Reaching and defeating Wave 7 will summon Betsy. If the Eternia Crystal is destroyed before you defeat her, the event fails, and you will need to restart from Wave 1.

Preparing to Face Betsy

Betsy is no pushover. She requires solid gear and a well-thought-out strategy. Having the right equipment is paramount to your success.

Recommended Gear

Armor: Post-Golem armor sets like Beetle Armor, Tiki Armor, or Shroomite Armor provide significant defense and damage boosts.
Weapons: Ranged and magic weapons tend to be effective against Betsy, as she is constantly flying. Consider weapons like the Tactical Shotgun, Tsunami, or Razorpine. Magic users might find success with Spectre Staff, Inferno Fork, or Blizzard Staff.
Accessories: Wings are essential for maneuverability. High-tier wings like Fishron Wings, Betsy’s Wings (if you’ve already beaten her once), or Empress of Light Wings are highly recommended. Other useful accessories include Celestial Emblem, Avenger Emblem, and the Ankh Shield for immunity to debuffs.

Arena Setup

A well-prepared arena can make a significant difference. Consider these factors:

Flat Terrain: Ensure the arena is relatively flat to allow for easier movement.
Lighting: Proper lighting helps you see enemies clearly.
Traps: Strategically placed traps like Spiky Ball Traps, Flame Traps, and Super Dart Traps can help thin out the hordes of enemies before Betsy even arrives.
Buff Stations: Campfires, Heart Lanterns, and Bast Statues provide valuable regeneration and defense buffs.

Battling Betsy: Strategies and Tactics

Betsy’s attack pattern involves flying, charging, and spewing projectiles. Understanding her attacks is vital to dodging them.

Movement: Keep moving and use your wings to stay airborne. Avoid standing still, as she can quickly close the distance.
Dodging: Pay attention to her flight patterns and dodge her charges. Sideways movement is more effective than trying to outrun her.
Projectile Avoidance: Watch out for her fireballs and try to predict their trajectory.
Damage Focus: Concentrate your attacks on Betsy as quickly as possible. The faster you defeat her, the less time you have to deal with the constant stream of other enemies.
Potions: Don’t forget to use potions like Ironskin, Regeneration, Swiftness, and Lifeforce to boost your survivability. A Well Fed buff will also provide a small but noticeable advantage.

Rewards and Drops

Defeating Betsy guarantees you one of four unique weapons:

Aerial Bane: A bow that fires piercing arrows.
Sky Dragon’s Fury: A powerful magic weapon.
Betsy’s Wrath: Another strong magic weapon that applies a defense-lowering debuff.
Flying Dragon: A melee weapon that shoots dragon-shaped projectiles.

She also has a chance to drop Betsy’s Wings and the Betsy Mask. In Master Mode, Betsy will always drop the Betsy Relic and has a 25% chance to drop Betsy’s Egg, which summons the Itsy Betsy pet. Betsy also drops a Treasure Bag, even in normal mode.

FAQs About Betsy

1. What are Defender Medals used for?

Defender Medals are a unique currency earned during the Old One’s Army event. They can be used to purchase items from the Tavernkeep NPC, including armor sets, weapons, sentry summons, and the Eternia Crystal and Stand.

2. Can I fight Betsy multiple times?

Yes, you can initiate the Old One’s Army as many times as you want, allowing you to fight Betsy repeatedly to obtain all her drops or to farm Defender Medals.

3. What happens if I die during the Old One’s Army event?

If you die, you will respawn at your spawn point. You can then return to the arena and continue fighting. The event will continue even if you die, so you can still succeed as long as the Eternia Crystal is not destroyed.

4. Is Betsy harder than Duke Fishron?

While both are challenging bosses, the difficulty varies based on your gear and skill. Duke Fishron relies more on player skill, while Betsy benefits from having top-tier, post-Golem gear. Some players find Fishron harder due to his speed and aggressive attack patterns, while others find Betsy harder due to the waves of enemies accompanying her.

5. What is the best class to fight Betsy?

There is no single “best” class. Each class has its strengths and weaknesses. Ranged and magic classes generally perform well due to Betsy’s aerial nature, but a well-geared melee character can also succeed. The key is to adapt your strategy to your preferred playstyle and gear.

6. Can I summon Betsy in pre-Hardmode?

No, Betsy and the Tier 3 Old One’s Army event require you to be in Hardmode and to have defeated the Golem boss.

7. Does Betsy have any weaknesses?

Betsy has a large hitbox, making her relatively easy to hit. Also, some players have found success using weapons with piercing capabilities to damage multiple segments of her body simultaneously.

8. What is the significance of Betsy being a Dungeon Defenders 2 boss?

Betsy’s inclusion in Terraria is a crossover event, celebrating the collaboration between the two games.

Tier 2: Hardmode, accessible after defeating any Mechanical Boss.
Tier 3: Hardmode, accessible after defeating Golem. Betsy only appears in Tier 3.

10. What is Betsy’s Curse?

Betsy’s Curse is a debuff applied by the Betsy’s Wrath magic weapon. It reduces the target’s defense by 40 for 10 seconds, making them more vulnerable to damage.

11. Is the Flying Dragon better than the Terra Blade?

The Flying Dragon and Terra Blade are both powerful melee weapons, but they excel in different situations. The Flying Dragon has higher base damage and can penetrate multiple enemies, making it good for crowd control. The Terra Blade is better for single-target damage due to its homing projectiles.

12. What is the best modifier for Betsy’s Wrath?

The best modifier for Betsy’s Wrath is Mythical, as it provides a boost to damage, critical strike chance, mana cost reduction, and speed.

13. Can I build a farm to automate the Old One’s Army event?

While fully automating the event is difficult due to the need to activate the Eternia Crystal, you can build a farm that significantly simplifies the process. This typically involves creating a box around the Eternia Crystal Stand and using traps and sentries to deal with the majority of the enemies.

14. What is the Itsy Betsy pet?

The Itsy Betsy is a pet summoned by using Betsy’s Egg, which has a chance to drop from Betsy in Master Mode. The Itsy Betsy is a miniature version of Betsy that follows the player around.

15. How does the Old One’s Army event contribute to gameplay?

The Old One’s Army event introduces a tower defense element to Terraria, requiring players to strategically build defenses and manage resources to survive waves of enemies. It also offers unique rewards and challenges that encourage players to experiment with different strategies and builds.
