Step-by-Step Guide to Weapon Upgrades

1. Visit the Blacksmith at the Forest Castle Forge:
– The first step is to find the Blacksmith located at the Forge near Forest Castle. This location can be accessed via the Royal Chamber save point; simply navigate to the right and descend one level.
– You’ll need to move a large block to gain access to the forge.
– The local smith there can upgrade your weapons from Level 1 to Level 3 and will inform you about the specific materials needed for each upgrade.

2. Level 4 Upgrades with Master Swordsmith Masamune:
– For upgrading your weapons to Level 4, you need to locate Master Swordsmith Masamune. He is another blacksmith found deeper within the Forest Castle area.
– Be aware that he can be easily missed, but you can return to the Forest Castle later in the game to access him.
– Upgrading a weapon to Level 4 not only enhances its performance but also contributes towards achieving notable trophies or achievements and is necessary for unlocking Ending Y of the game.

3. Required Materials for Upgrades:
– Each weapon requires specific crafting materials for upgrades, which players can collect as they progress through the game.
– Materials are usually obtained from defeated enemies, discovered in various locales, or awarded upon completing certain quests.

– Titanium Alloy
– Dented Plate
– Severed Cable
– Amber
– Rusted Clump
– Broken Circuit
– Warped Wire
– Coils (often required for specific weapons)
– Because each weapon has its unique upgrade requirements, consult the Blacksmith or reference detailed in-game resources for specific material needs pertinent to the weapon you want to enhance.

4. Summary of the Upgrade Process:
– Begin by visiting the forge at Forest Castle to perform upgrades from Level 1 to Level 3.
– Gather the required materials and monetary resources as indicated for each of the weapons.
– Once you have access to Masamune, seek him out to carry out the final Level 4 upgrades.
– Finally, aim to upgrade all of your weapons to Level 4 for complete weapon narratives and to achieve related accolades in the game.
