Understanding Upgrade Materials
Mortal Shell II uses various materials for weapon and Shell upgrades. The most commonly referenced are Tarstones, which are used at upgrade anvils to improve weapon damage, posture pressure, and special effects.\n\nImportant: The developer has not published a complete, patch-stable upgrade database. Material names, drop sources, and costs can change between patches. This guide focuses on safe farming principles rather than asserting exact coordinates or drop rates.
Where to Find Materials
Upgrade materials come from several sources:\n\n1. Enemy drops: Common enemies drop basic materials. Mini-bosses and dungeon enemies drop higher-tier materials.\n2. Environmental loot: Chests, corpses, and hidden caches contain materials.\n3. Vendors: Some merchants sell materials for currency. Check vendor inventories whenever you reach a new safe area.\n4. Boss rewards: Major bosses often drop rare materials not found elsewhere.\n\nBecause the Open Beta economy differed from retail, guides created before August 20, 2026 may list incorrect locations or costs. Verify the guide's date before following farming routes.
Safe Farming Routes
A safe farming route has three qualities:\n\n1. Short: You can complete it in 5–10 minutes.\n2. Repeatable: Enemies respawn when you rest at a Beacon.\n3. Low-risk: The enemies drop useful materials but do not consume all your healing.\n\nHow to build your own route:\n1. Identify a Beacon near a group of enemies that drop materials you need.\n2. Clear the group, collect drops, and return to the Beacon.\n3. Rest to respawn enemies and repeat.\n4. If the encounter is too dangerous, find an easier group. Efficiency matters more than drop rarity if you die and lose progress.\n\nRecord your route: enemy types, drops observed, time per run, and healing consumed. This lets you compare routes objectively.
Material Conservation Rules
Until a material is verified as renewable in your patch, treat it as potentially finite:\n\n1. Keep at least one copy of every rare material until you know its source.\n2. Before spending a material, verify the upgrade result in the menu. Some upgrades are irreversible.\n3. Do not spend rare materials on weapons you have not tested extensively.\n4. Record every material spent: name, source, quantity, upgrade result, and date.\n\nIf a vendor sells the material, note their restock behavior. Some vendors restock after boss defeats; others may have limited inventory.
Vendor vs Farming: Which Is Better?
Buying materials is safer than farming when the enemy that drops the material is difficult or time-consuming, you have excess currency and no better use for it, or the vendor price is lower than the time cost of farming.\n\nFarming is better when the enemy group is easy and near a Beacon, you also need enemy-specific drops such as common crafting materials, or the vendor does not sell the material or is out of stock.\n\nThe optimal approach is usually a mix: buy what is affordable and farm the rest.
