Mastering how to upgrade enchanted arms Tome of the Damned requires harvesting Souls from fallen castle guards and sacrificing them at the Altars located between dungeon floors. The game operates on a dual-progression system that punishes players who blindly hoard currency. You must balance unlocking permanent base weapons in your central Lair with drafting temporary, high-impact stat boosts during your actual dungeon escape attempts.
The core loop demands aggression. Every enemy you slay drops a specific amount of Souls, the lifeblood of your progression. Standard guards offer a pittance, while Elites and Bosses drop massive clusters. Understanding where to spend these Souls—and which weapons actually scale well into the late game—is the difference between escaping the castle and being sent back to the Lair in a new corpse.
Meta-Progression vs. In-Run Altars
Progression in this dark fantasy roguelike is split into two distinct economies.
The Lair (Permanent Unlocks) When your possessed body is destroyed, your spirit returns to the Lair deep within the castle. Here, you spend your accumulated Souls to permanently unlock new base weapons and elemental magic books. Once you purchase a weapon here, it enters your permanent loot pool and can be equipped at the start of any future run.
Sacrificial Altars (Temporary Drafts) During a run, you will encounter blood-stained stone tables in the safe rooms between dungeon floors. These are the Sacrificial Altars. Spending Souls here does not unlock new gear; instead, it grants temporary, run-specific buffs to your currently equipped weapon. These upgrades are lost upon death, but they are mandatory for scaling your damage output to match the inflated health pools of late-game bosses.
Optimal Soul Farming Routes
Maximizing your Soul income means optimizing your path through the prison levels. Start in the 'Lower Dungeons' where basic guards yield 10 Souls each. Move quickly to the 'Torture Chambers' to hunt Elites worth 50 Souls. Avoid the optional 'Dark Chapel' early on, as the Mages there resist physical damage and slow your clear time. Finally, hit the 'Warden's Quarters' to challenge the floor boss for a guaranteed 500 Soul drop and a permanent upgrade material.

Do not waste time full-clearing the Lower Dungeons once you have enough Souls to purchase your first major upgrade. The enemy density is too low to justify the time spent. Push forward to the Torture Chambers as quickly as your build allows, as the Elite spawn rate there is significantly higher.
Unlocking the Five Core Weapons
The game features five distinct melee weapons, each with its own attack animation and base scaling. The Cursed Longsword is your balanced starter, offering a baseline 1.0 attack speed and moderate stagger. The Grave-Iron Greatsword drops your speed to 0.6 but triples your base damage, making it the premier choice for heavy burst builds. The Wraith Daggers hit at a blistering 1.8 speed but struggle against shielded enemies. The Blood-Steel Halberd provides maximum reach with a 1.2 speed, perfect for spacing out multiple foes. Finally, the Bone Scythe offers innate lifesteal at a 0.9 speed, trading raw damage for survivability.

Your starter weapon, the Cursed Longsword, is a liability past the first floor. Its base damage scaling falls off a cliff the moment you encounter heavily armored foes. Rush the Grave-Iron Greatsword unlock as your first permanent purchase in the Lair. The massive stagger potential of the Greatsword completely trivializes the shield-bearing enemies that otherwise wall new players.
The Best Altar Draft Choices
When you interact with a Sacrificial Altar, the game pauses and presents three randomized upgrade paths. You might see 'Shattering Strike', which increases base damage by 15% for 500 Souls. Alternatively, 'Zephyr Blade' boosts attack speed by 10%, a mandatory pick for heavy weapon users. If you are running a hybrid build, 'Elemental Conduit' bridges the gap, allowing your melee strikes to apply status effects from your equipped grimoire. You can reroll these choices once per floor if you possess a Warden Core.

Never pick flat damage upgrades for the Wraith Daggers; their base damage is too low to benefit from percentage increases. Instead, draft on-hit effects and critical strike chance. Conversely, the Grave-Iron Greatsword scales exponentially with 'Shattering Strike'. If you see 'Zephyr Blade' while wielding the Greatsword, take it immediately—reducing the wind-up animation of your heavy swings is the single most important defensive upgrade in the game, allowing you to strike and dodge before retaliatory hits connect.
Synergizing Melee with Elemental Grimoires
Your enchanted arm is only half of your offensive toolkit. The other half relies on the four elemental grimoires you unlock in the Lair.
- Inferno Tome: Applies a stacking burn damage-over-time effect. Pairs perfectly with the fast, multi-hit strikes of the Wraith Daggers.
- Frostbite Codex: Provides hard crowd control, freezing enemies in place. This allows you to land the agonizingly slow, high-damage overhead swings of the Grave-Iron Greatsword without being interrupted.
- Storm Grimoire: Chains lightning between tightly packed mobs, compensating for the narrow, single-target hitbox of the Cursed Longsword.
- Void Ledger: Creates gravity wells that pull castle guards into a single clump, setting them up for the wide sweeping attacks of the Blood-Steel Halberd.
Never upgrade a weapon at an Altar without considering which grimoire you plan to use. A hybrid build that utilizes the Frostbite Codex to lock down targets before shattering them with a heavily upgraded Greatsword is currently the most reliable way to clear the game's final act.
Beating Early Bosses for Cores
Executing the Greatsword and Frostbite build requires a specific sequence through the first three dungeon floors. First, bait the Seasoned Warrior elite into a narrow corridor to easily dodge his lunges. Once he falls, collect his high-yield Soul cluster. Immediately swap out your starter blade for the Grave-Iron Greatsword. Next, cast 'Glacial Spike' from the Frostbite Codex to freeze the approaching mob. Finally, use the Greatsword's heavy overhead swing to shatter the frozen enemies before advancing to the Captain of the Guard boss room.

The Captain of the Guard is your first real DPS check. He heavily telegraphs his shield bashes, giving you exactly enough time to land one Greatsword swing before you need to roll. Defeating him yields a Warden Core, which is required to reroll bad RNG at the Sacrificial Altars. Save this Core for the late-game floors where a poor Altar draft can instantly end your run.
Surviving the Flooded Catacombs
The atmosphere of the dungeon shifts drastically once you reach the flooded catacombs. Rusted iron bars give way to crumbling stone arches, and the shadow purple lighting reflects off the stagnant water. Here, the undead mages hide behind pillars, waiting to ambush you with void magic. You must use the environment to your advantage, breaking line of sight behind the massive statues of forgotten kings to avoid their tracking projectiles.

In this biome, raw damage matters less than mobility. If you invested heavily into the Blood-Steel Halberd, use its superior reach to poke the mages from behind cover. Do not attempt to rush them across the deep water, as your movement speed is severely penalized, leaving you open to their devastating area-of-effect spells.
Frequently Asked Questions
Can you respec weapon upgrades? In-run Altar upgrades are permanent for that specific life cycle. Once your possessed body is destroyed, those draft choices reset. However, the base weapon unlocks purchased with Souls in the Lair are permanent across all future runs.
Do upgrades carry over when you die? Only meta-progression unlocks carry over. If you spend 2,000 Souls to permanently unlock the Grave-Iron Greatsword, it remains available in your armory forever. The temporary stat boosts (like +15% base damage) acquired at the Sacrificial Altars are lost upon death.
What happens to the body possession mechanic? When your current host body dies, your mage spirit returns to the Lair. You must select a new corpse to possess before starting the next run. Different corpses offer minor starting stat variations, such as increased stamina recovery or higher base health, which can influence which enchanted arm you choose to equip.
How do I beat the Grand Inquisitor? The Grand Inquisitor resists elemental magic, rendering the Inferno Tome and Storm Grimoire nearly useless. Equip the Blood-Steel Halberd to out-range his holy AoE attacks, and focus entirely on raw physical damage upgrades at the Altars leading up to his boss room.
