I booted the Onimusha: Way of the Sword demo expecting the linear 2004 franchise brawler I grew up with. Instead, I hit a wall of permanent, resource-gated build choices that defined my entire playthrough from the first hour onward. Forget mindless button mashing — every Red Soul I spent and every skill node I unlocked locked me out of alternate paths. Early missteps became a common frustration for me as a returning player after the 20-year hiatus.
The Three-Currency Skill Tree System
Progression is split into three discrete categories, each requiring a unique, non-interchangeable currency. I learned this the hard way when I dumped all my Power Stones into charm slots and then realized I had no movement upgrades for the first boss.
| Currency | Used For | Key Notes |
|---|---|---|
| Power Stones | Basic Skills: core combat perks, movement, charm slot expansions | Non-interchangeable |
| Oni Stones | Special Oni Skills: Oni Awakening duration, Oni Vision, Oni attribute bonuses | Non-interchangeable |
| Red Souls | Oni Armament Skills: 3 unique perks per each of the 6 Oni Armaments | Finite per single playthrough |
Red Souls are the most painful. Every node I unlocked for one armament was permanently unavailable for the others. That core tension of build crafting hit me in the first hour. I started cross-referencing community wikis before committing resources, because wasting Red Souls on low-synergy upgrades felt like a punch to the gut.
Four Equipment Upgrade Tracks and What They Actually Change
All equipment upgrades draw from the same finite Red Soul pool as Oni Armament Skills. That ties my gear path directly to my skill tree choices. I had to decide: do I want raw damage, survivability, soul farming, or utility?
⚔️ Katana upgrades boost raw attack and Issen critical damage.
?️ Clothing upgrades increase health and stamina pools.
? Gauntlet upgrades extend Soul-Vacuum range, speed up absorption, and cut Oni Power cooldowns.
? Abilities upgrades unlock utility tools like the bow, stealth mechanics, and environmental interactions.
I skipped Gauntlet upgrades on my first run. That led to the community-dubbed Gauntlet-Gating issue. In late-game Malice zones, Soul-Vacuum windows are drastically shortened. I couldn't capture souls fast enough. I died. A lot. ?
The Charm System: Where True Build Identity Lives
Charms are equippable passive items that push my build into a distinct archetype. Total equip slots are tied to Power Stone investments in the Basic Skills tree. The community has settled on three core viable archetypes, and I tested all of them.
Aggressive builds use Sealed Curse and White Lion charms to trade defense for raw damage.
Defensive builds run parry window extenders and health regen charms for consistent survivability.
Resource farming builds stack Kubi Akari and Lion Dog charms to boost Red Soul drop rates.
Expanding charm slots requires forgoing other Basic Skill upgrades. That adds another layer of permanent resource trade-off to my build planning. I found myself sketching node paths on paper like some kind of medieval accountant. ?
New Game+ and the Long-Term Build Loop
New Game+ Carnage Mode follows a specific, build-defining rule: all skill tree unlocks carry over to subsequent runs, but all gear levels and unspent Red Souls are fully reset. That makes my first playthrough effectively a build-drafting run. I tested core mechanics before committing to a fully optimized endgame build.
Players planning multiple NG+ runs to test different playstyles often use top-up services to ensure uninterrupted game access across playthroughs. I haven't needed that yet, but I get why they do. Popular endgame builds include Chain-Issen focused loadouts and Oni Awakening extension loadouts. They play drastically differently for high replay value.
Quick Build Starter Recommendations
Below are three low-friction starter builds for first-time players, with no wasted resource allocation. I wish I had this list before I started.
First Run Balanced: Unlock the first two Katana base damage nodes, first two Clothing health nodes, and first Gauntlet Soul-Vacuum speed node. No niche charm investment needed. Works for all early to mid-game content.
Issen-Fisher: Prioritize Katana Issen critical damage nodes first, pair with White Lion and Sealed Curse charms, and sink all Oni Armament Red Souls into your single preferred weapon. High-risk, high-reward parry-focused play. I tried this on my second run and loved it.
Soul-Farmer: Invest in the first three Gauntlet upgrade nodes, stack two Lion Dog charms, and unlock Oni Vision nodes in the Special Skills tree to farm extra Red Souls for your second playthrough. Perfect if you already know you'll do NG+.
Before spending any Red Souls on your first run, cross-reference upgrade paths and costs on community databases to avoid irreversible misallocation. No mid-run resets are available. I learned that the hard way, and I don't want you to make the same mistake. Trust me — your future self will thank you. ?
