Weapon upgrades in Code Vein 2 hinge on acquiring key materials, among which Tender Light Stone 4 is particularly rare. While Tender Crimson is plentiful and widely available, Light Stones are deliberately limited, ensuring that players must engage in specific quests and exploration to access them.

The primary method to obtain Tender Light Stone 4 takes players to Insula Carcere, during the search for the fourth hero following the defeat of the prior three heroes and their Hero versions. The island is a complex prison environment, requiring careful navigation through multiple cells and corridors. Players should be prepared for a variety of enemy encounters that gradually increase in difficulty as they progress toward the Zenon Gryfgote.

A key location is a room containing three doors with a small central cell. Here resides the standard Darkborn Leader enemy, while the back door opens to an outdoor area with easily defeated enemies. If players overlook this area, the Upper Cell Block Mistle nearby provides a secondary access point to continue progression.

In this zone, players will encounter Jadwiga’s Minion, who sells a single Tender Light Stone 4 for 4,290 Haze. More importantly, the Minion offers the Exclusive Customer Token: 04 for 17,160 Haze, which allows for the purchase of unlimited Tender Light Stone 4 at Jadwiga’s shop in MagMell. Although initially expensive, this method provides a sustainable source of Light Stones, allowing continuous weapon upgrades. Players can also generate additional Haze by defeating the Darkborn Leader enemy for 4,500 Haze per kill, offsetting the cost of the token over time.

For players aiming to fully upgrade their arsenal and tackle upcoming challenging encounters in Code Vein 2, securing access to the game through a reliable source is essential. Purchasing Code Vein II CD Keys via trusted marketplaces like z2u.com ensures immediate entry to the game, enabling players to gather resources efficiently and enhance their weapons to meet the escalating difficulty.
