Terraria Guide to Old World Parkour

To get the Guide to Old World Parkour in Terraria, you must defeat the Old One’s Army event and then purchase it from the Tavernkeep for 25 Defender Medals. This item is a light pet that summons a miniature version of the Tavernkeep, and it is purely cosmetic, providing no gameplay bonuses.

What Is the Guide to Old World Parkour?

The Guide to Old World Parkour is a light pet item introduced in the Old One’s Army crossover event with Dungeon Defenders 2. When used, it summons a small, floating Tavernkeep that follows you around and emits light, similar to other light pets like the Shadow Orb or Wisp in a Bottle. It does not attack enemies, provide stat boosts, or assist in combat—it is strictly a cosmetic companion with a light-giving function.

Many players confuse it with the Tavernkeep NPC himself or with the various sentry weapons he sells. The Guide is a separate item, and obtaining it requires progressing through the event’s difficulty tiers.

Prerequisites: Unlocking the Old One’s Army

Before you can earn Defender Medals and buy the Guide, you must first unlock the Old One’s Army event. This requires:

• Defeating the Eye of Cthulhu (to make the Tavernkeep appear in your world).
• Finding the Tavernkeep NPC, who spawns randomly after the Eye is defeated—he may be in any empty house or wandering the surface.
• Speaking with him and accepting his quest to defend the Eternia Crystal.

The event is triggered by placing an Eternia Crystal Stand (purchased from the Tavernkeep for 1 gold) and then placing an Eternia Crystal on it. You must defend the crystal from waves of enemies for a set duration. The event has three difficulty tiers: Tier 1 (normal mode), Tier 2 (after defeating the Wall of Flesh), and Tier 3 (after defeating the Golem).

How to Get the Guide: Step-by-Step

Follow these steps to obtain the Guide to Old World Parkour:

1. Defeat the Eye of Cthulhu to spawn the Tavernkeep.
2. Locate the Tavernkeep and talk to him. He will give you a basic explanation of the event.
3. Purchase an Eternia Crystal Stand from him (costs 1 gold) and place it in a flat, open area.
4. Buy an Eternia Crystal (costs 25 silver) and place it on the stand to start the event.
5. Survive the waves until the event ends. You do not need to defeat every enemy—just prevent the crystal from being destroyed.
6. Collect Defender Medals dropped by enemies and awarded at the end of the event. The number scales with the tier.
7. Return to the Tavernkeep and open his shop. The Guide to Old World Parkour will be available for 25 Defender Medals.

You can repeat the event as many times as you like to farm medals. The Guide is always available once you have the medals, regardless of your game progression.

How to Use the Guide

Once purchased, the Guide to Old World Parkour functions like any light pet:

• Equip it in your light pet slot (the slot above your armor, next to the pet slot).
• Activate it by pressing the corresponding key (default is B on PC) or by right-clicking the item in your inventory.
• The Tavernkeep mini will follow you, emitting a soft yellow light that illuminates a small radius around you.
• It does not consume any mana, ammunition, or durability—it is a permanent item.

Unlike normal pets, light pets do not take damage and cannot be killed. They are purely cosmetic, so you can use them without any risk.

Why You Might Want It (and Why Not)

The Guide is a novelty item, but it has a few niche uses:

• Light source: It provides a hands-free light source, useful in dark caves or during night exploration.
• Aesthetic: If you enjoy collecting pets or want a Tavernkeep companion, it’s a fun addition.
• Completionism: It’s required for the “Terraria Expert” achievement (if you’re collecting all items).

However, it is not a practical choice for serious gameplay. Other light pets, like the Wisp in a Bottle (from post-Plantera dungeons) or the Shadow Orb (from the Corruption), provide better light coverage. The Guide’s light radius is relatively small and the pet can sometimes get in the way of your view.

Common Problems and Misconceptions

Players often run into a few issues when trying to get the Guide:

• Tavernkeep not spawning: Ensure you have defeated the Eye of Cthulhu. If he still doesn’t appear, check if you have an empty house available—he needs a valid housing slot.
• Not enough Defender Medals: The event gives medals based on performance. On Tier 1, you might only get 5-10 medals per run. You may need to run the event multiple times. To speed this up, use sentry weapons (which the Tavernkeep sells) and place them near the crystal.
• Can’t find the item in the shop: The Guide is only available after you have completed at least one Old One’s Army event. If you haven’t done so, the shop will not show it.
• Confusing it with the Tavernkeep’s other items: The Tavernkeep also sells sentry summon weapons, the Eternia Crystal Stand, and the Eternia Crystal. The Guide is a separate item in the shop, usually listed under “Light Pets.”

Comparing the Guide to Other Light Pets

If you’re considering the Guide, it’s worth comparing it to other light pets available in Terraria:

• Shadow Orb (Corruption) / Crimson Heart (Crimson): Obtained by breaking the first orb or heart in the respective evil biome. They provide a decent light radius and are available early-game.
• Wisp in a Bottle: Found in post-Plantera Dungeon chests. It provides a larger light radius and can pass through walls, making it superior for exploration.
• Magic Lantern: Dropped by the Skeleton Merchant. It reveals nearby enemies, but provides less light than the Guide.
• Guide to Old World Parkour: Cosmetic value only, with a small light radius. It’s more of a collectible than a practical tool.

If you want the best light pet, go for the Wisp in a Bottle. If you want a fun companion, the Guide is fine, but don’t expect it to be a game-changer.
