Lost Castle 2 diverges from conventional RPG elements by foregoing a traditional skill tree and character leveling system. Instead, it introduces a compelling Camp Upgrade feature, allowing players to acquire permanent skills and enhancements. Mastering this upgrade system is crucial for maximizing your character’s potential, boosting replayability, and effectively accessing the end-game content.
This guide delineates the Camp Upgrades featured in Lost Castle 2, elaborates on their acquisition process, and suggests prioritization strategies for optimizing your Skill Tree experience.
Understanding Camp Upgrades

In Lost Castle 2, Camp Upgrades represent permanent enhancements that elevate your character’s abilities. Unlike other items like Weapons, Amulets, Treasures, and Armor sets, which are reset after each expedition, Camp Upgrades mirror the function of a skill tree, offering continuous buffs, amenities, and privileges.
There are a total of 33 Camp Upgrades divided into three essential categories: the Blacksmith Shop, the Alchemist’s Hut, and the Ethereal Statue. Although the goal is to unlock all these upgrades, new players should initially concentrate on those that yield the most significant benefits.(Refer to the priority guide provided below.)
How to Initiate Camp Upgrades

To commence Camp Upgrades, interact with Armstrong, a character holding a log, or approach the table adjacent to him. Each upgrade requires Coins, which currently serve as the exclusive currency in the game, so it’s advisable not to hoard them.
Coins can only be obtained by successfully clearing various areas, as they are awarded in small quantities upon completing objectives.

Prioritizing Skill Trees

The optimal sequence for unlocking Camp Upgrades in Lost Castle 2 progresses left to right: 1) Blacksmith, 2) Alchemist’s Hut, and 3) Ethereal Statue. Upgrades from the Blacksmith enhance your character’s development speed and exploration potential, while those from the Alchemist’s Hut and Ethereal Statue bolster your defensive capabilities and facilitate the collection of Soul Crystals—vital for acquiring superior gear during your quests.
Watch here for more tips
For players confident in their combat abilities, it might be wise to prioritize upgrades from the Ethereal Statue. These upgrades allow quicker access to end-game experiences, albeit requiring you to navigate dungeons without immediate increases to ATK, HP, or DEF stats, since the Ethereal upgrade tree focuses on enhancing Ethereal attributes and increasing Soul Crystal gains.
