What is the Castle ?
The Castle is a fun feature within Dragalia Lost where players can construct and upgrade buildings to help them on their adventures. Progressing here is critical, as upgrades directly affect adventurer’s stats, weapons and dragons.
Although upgrades can take a long time, they happen passively, so the rule of thumb is to upgrade aggressively for increasing returns. Keep Dragon Helpers active while progressing through the main story, and check in to hit the "collect all" button between quests.
The Castle can be accessed after completing Chapter 1 of the Campaign.
Elemental weapons are the goal for the Smithy, as matching a character’s element to their weapon increases damage tremendously. This requires an enhanced Smithy, which is only attainable after upgrading the Halidom to level 2. The heart of crafting doesn’t begin until later in the game, so basic upgrades to the Smithy will suffice early on.
The Halidom has a variety of boosting structures available. Altars give passive element-specific stat boosts, while mines produce Rupies. Decorations are purely cosmetic and for fun. Every structure and upgrade has a price, which is usually Rupies but can also include various materials earned through gameplay.
There are three kinds of stories that can be unlocked within the Halidom: Adventurer, Dragon, and Castle stories. These are short independent side-stories focusing on characters in your party, unlocked through recruitment and the Mana Circle. Reading or skipping these will award 25 Wyrmite per episode.
Visit the Dragon Roost to feed the dragons, increasing their friendship level. Although this is separate from their upgrade level, it does extend the duration of any transformation as that particular dragon. The dragon will also give gifts out of gratitude, usually in the form of dragonfruit or other materials.
