Lost Soul Aside blends stylish hack-and-slash combat with RPG progression, and mastering its skill system is key to surviving tougher encounters. While every weapon tree offers unique playstyles, some upgrades stand out as early priorities. This guide breaks down the best skills across different weapons and categories so you can maximize Kaser’s potential from the start.
Why You Need Skills in Lost Soul Aside
The game pushes players into challenging battles within the first hour, and your success depends heavily on how quickly you unlock and combine abilities. Some skills enhance survivability, others streamline combat flow, and a few transform average attacks into game-changing combos. By prioritizing the right upgrades, you’ll maintain momentum in both boss fights and enemy waves.

It also helps to understand when new stances unlock: Greatsword, Poleblade, and Scythe are each tied to restoring Arena’s power as the story progresses. Knowing this helps you plan your skill investments early.
Essential Utility Skills in Lost Soul Aside
Potion Pouch Expansion
- Effect: Increases the number of Healing Potions Kaser can carry.
- Why It’s Important: You begin with a cap of five potions, but this upgrade allows expansion up to ten when unlocked across weapon trees. Since chests are rare and NPC restocks aren’t always available, extra potions drastically improve survivability during long missions.
Healing Potions restore about 30% HP and High Potions restore around 70% HP, making this expansion vital for long levels and boss fights.
Arena Power Slot & Trinket Slot
- Effect: Adds extra slots for Arena Powers and trinkets.
- Why It’s Important: Starting with just one trinket and one Arena Power feels restrictive. Expanding these slots lets you equip multiple passive buffs and combat powers simultaneously, giving you much more flexibility in building your strategy. The Arena Power Slot is especially impactful, letting you chain three special powers for explosive fights.
Prioritize Arena Power Slots first, since they dramatically boost encounter flexibility, while Trinket Slots can follow afterward.
Lost Soul Aside Best Sword Skills for Damage and Combos
Heavy Cleave → Shadow Rend
- Effect: Heavy Cleave closes distance with a powerful slash; Shadow Rend evolves it into a flurry of rapid strikes reminiscent of Vergil’s Judgement Cut.
- Why It’s Important: These skills transform the sword from a basic starter weapon into a devastating DPS tool. Pairing them with Burst Pursuit upgrades like Shadow Flash and Obliteration turns Kaser into a relentless force.
Eagle Strike
- Effect: Allows a smooth transition from aerial combos back to the ground.
- Why It’s Important: Aerial slashes are strong, but without this skill, landing back on the ground feels clunky. Eagle Strike ensures seamless combo flow, making you faster and less vulnerable.
Lost Soul Aside Best Greatsword Skill
Spinning Thrust
- Effect: Converts the slow Earth Sever heavy attack into a rapid spinning combo, with an optional upgrade into Waterspout.
- Why It’s Important: Greatsword users often struggle with sluggish animations. Spinning Thrust fixes that, letting you maintain pressure while still dealing heavy damage. Waterspout, the Burst Pursuit follow-up, extends the combo and keeps pressure on enemies after the initial spinning strike.
Best Poleblade Skills
Enhanced Poleblade
- Effect: Fires more phantom projectiles with a single heavy attack.
- Why It’s Important: Ranged pressure is rare in Lost Soul Aside. This skill turns the Poleblade into a versatile hybrid weapon, allowing safe chip damage or finishing enemies at a distance. Upgrading it with Air Blast makes it even deadlier
Spinning Strike / Whirling Strike
- Effect: Kaser spins rapidly on the ground (Spinning Strike) or in the air (Whirling Strike), draining stamina while damaging enemies.
- Why It’s Important: Perfect for breaking enemy or boss shields quickly. While stamina drain is a drawback, the payoff in shield-breaking efficiency makes these skills worth unlocking.
Best Scythe Skill
Burst Pursuit: Void Array
- Effect: Turns dodging into an offensive move, creating three columns of energy that can be detonated.
- Why It’s Important: This skill rewards defensive play by adding extra damage opportunities. Press R2/RT at the end of a dodge to leave Arrays behind; detonate them immediately for damage or leave them as traps for pursuing enemies. It’s one of the best skills against aggressive bosses.
Beginner Build and Skill Synergy
If you’re just starting out, a strong beginner build combines these skills:
- Sword Core: Heavy Cleave, Shadow Rend, and Phantom Slash for aggression.
- Utility: Potion Pouch Expansion and extra Arena Power Slots.
- Burst Option: Burst Pursuit: Obliteration for massive payoff after parries.
Recommended Early Loadout: Use Empire Glory as your starter weapon, swap to Goldrose after Rose Queen if you prefer its feel. Equip Frost Blast Arena Power (after Lord Golden Lion) instead of Voidmaw, and wear Bracelet of GLIMMER to boost Attack after Perfect Dodges.
Core Combat Loop: Perfect Dodges and Parries build both your Burst Pursuit and Fusion Merge meters. After a parry, charge Burst Pursuit: Obliteration to punish safely. Watch for Sync Finisher prompts to unleash a multi-hit strike while gaining invulnerability frames. Aim to reach Fusion Merge quickly and transform as often as possible.
Quick Tips
- Prioritize survivability first. Extra potions and trinket slots will carry you through the steep learning curve.
- Invest in weapon evolution skills. Many starter attacks feel weak until upgraded (e.g., Spinning Thrust, Enhanced Poleblade).
- Experiment with Arena Powers. Unlocking more slots early ensures you can adapt your loadout for different encounters.
The best skills in Lost Soul Aside aren’t just about raw damage—they enhance fluidity, survivability, and versatility. Whether it’s chaining sword combos with Shadow Rend, firing projectiles with Enhanced Poleblade, or turning dodges into counterattacks with Void Array, these upgrades define your combat rhythm. Unlock them early, and you’ll find Kaser’s journey much smoother and far more stylish. Play Now!
