TL;DR
- Both the Lightningblade of Greed and Storm Fang come from defeating Sizlek the Insatiable at the Ruined Chapel in southeast Hernand.
- You must complete most Hernand faction side quests before Sizlek’s quest unlocks — it’s the final Hernandian Parish of Solumen mission.
- The key quest trigger is: complete the House Celeste “Legendary Animals” questline, then look for “Mysterious Arrow” at Glenbright Farm south of Hernand.
- Sizlek drops the Lightningblade of Greed, the Goldbranch Plate Crown (which holds Storm Fang), and Shadow Gloves.
- Storm Fang is armor-only and only activates when you use Lightning-imbued attacks — unlock Lightning first through Chapter 4 Abyss quests.
- The Lightningblade of Greed does NOT deal lightning damage in your hands — it’s a solid Critical Rate sword, nothing more.
- Have a Kuku Pot ready and Focused Force Palm unlocked before entering the Bloodied Sanctum.
Sizlek the Insatiable is a goblin boss sitting behind one of the longest quest chains in Crimson Desert — but the reward is genuinely worth it. You get two items from this fight: the Lightningblade of Greed, a one-handed sword with a built-in Critical Rate bonus, and Storm Fang, one of the best elemental Abyss Gears in the game for lightning builds. This guide covers the full quest order, exact boss location, fight tips, and what you actually get from each drop.

What Are the Lightningblade of Greed and Storm Fang?
Lightningblade of Greed
The Lightningblade of Greed is a Rare-grade one-handed sword with a base Attack of 10. It was crafted by Sizlek the Insatiable and is described in lore as a blade designed to channel recklessly powerful electrical currents. It looks fantastic — a crackling lightning sword carried by a goblin warlord — but there’s an important caveat: it does not deal lightning damage when you use it. Despite the name and the visuals on Sizlek, the sword in your hands is functionally identical to any other one-handed sword with a Critical Rate bonus.
If you want a weapon that actually shocks enemies with every hit, the Electro-Mecha Longsword is the better choice for a true lightning weapon build. That said, the Lightningblade of Greed is still a solid one-handed sword — its Critical Rate stat pairs well with stacked Insight III Abyss Gears. Check our Best One-Handed Swords guide to see how it stacks up against alternatives.
Storm Fang (Abyss Gear)
Storm Fang is the real reason to fight Sizlek. It’s an Abyss Gear that adds a chain lightning effect to your imbued attacks. Specifically, when you use the Lightning element through Imbue Element, Storm Fang causes your attacks to send out bolts of chain lightning that arc between nearby enemies. This makes it extremely effective in group combat — one imbued hit can chain-shock multiple enemies at once, dealing bonus damage and building stagger on all of them simultaneously.
Storm Fang is armor-only. It cannot go into weapon sockets. Extract it from the Goldbranch Plate Crown at any Witch and embed it into whichever armor piece you prefer. It also requires Lightning Lv 1 to activate — if you haven’t unlocked the Lightning element yet, Storm Fang won’t trigger regardless of where you slot it.
To understand how elemental attacks work before using Storm Fang, read our guide on how to use elemental attacks and imbue elements. For getting the Lightning element specifically, see our Lightning Surge and Courtyard of Precision guide.
How to Unlock the Sizlek Fight — Quest Order
This is where most players get stuck. Sizlek is the final boss of the Hernandian Parish of Solumen faction questline. You cannot fight him until you’ve completed the vast majority of Hernand’s side quests. There is no single unlock condition — it’s a chain of many quests across several Hernand factions, and the order can be confusing because some quests are locked behind others.
The best general rule is: complete all available quests for one faction before moving on to the next. Open your map, enable the Quests toggle, and clear every available marker in the Hernand region before expecting the Sizlek quest to appear.
Key Questlines That Lead to Sizlek
These are the main questlines you need to work through in Hernand before the Sizlek chain unlocks:
- House Celeste questlines — including the “Legendary Animals” questline, which is the second-to-last House Celeste chain and directly unlocks the Parish of Solumen’s final mission.
- Hernandian Parish of Solumen earlier quests — “Where Land Meets Sky” and “Missing Relic” are the two missions that open once you enter the Parish questline. Complete both.
- Valua Fishermen’s Guild — the mission “Beyond the Silent Waves” unlocks after the House Celeste quest “How Hands.” Complete it.
- House Felix — complete “Family Concerns” and “Shackle-Breaking Hammer” to open more of the Hernand quest tree.
- Hernand outlaw bounties — clear all nine outlaw bounties in the region. If you’re stuck at 8/9, clear the Vilcom Outpost on the map and return to any random post in Hernand to trigger the final bounty to spawn.
- House Circus — complete “Nemesis Demise.”
- Goldleaf Merchant Guild — complete “Extinguishing the Last Flames” and any other currently unlocked quests in this faction.
For bounty quests in Hernand, see related guides like our Aera Outlaw Bounty, Wolfe Outlaw Bounty, and Haldin Bounty guide to check them off faster.
Starting the Mysterious Arrow Quest
Once you’ve completed enough of the above questlines, head to Glenbright Farm, south of Hernand. A quest marker for “Mysterious Arrow” will appear there. Go to the marker, pick up the arrow on the ground, and read the note attached to it. This officially starts the final phase of the Hernandian Parish of Solumen chain and points you toward the Ruined Chapel.
Before you head in, make sure you have two things ready:
- A Kuku Pot in your inventory — you’ll need it for the dungeon ahead.
- Focused Force Palm unlocked in your skill tree — certain mechanics inside the Bloodied Sanctum require it. See our Focused Force Palm guide if you haven’t unlocked it yet.
Sizlek the Insatiable Location — Ruined Chapel, Bloodied Sanctum
Sizlek the Insatiable is found inside the Ruined Chapel, located near the Steel Mountains in southeast Hernand. The dungeon itself is called the Bloodied Sanctum, and it’s the climactic area of the entire Hernand Parish of Solumen questline. The fight takes place after you’ve cleared multiple waves of Fundamentalist Goblin enemies inside the sanctum.
The Bloodied Sanctum requires some traversal and enemy clearing before you reach Sizlek. Don’t rush through without food and healing items — the encounters ramp up quickly and test both crowd control and resource management. Stock up on your best food and bring Palmar Pills. Check our guide on how to cook the best healing food before going in, and see how to get and use Palmar Pills to keep a supply ready.
How to Beat Sizlek the Insatiable
Sizlek is a goblin boss with a notable electrical theme — he uses lightning-based attacks and hits harder than standard Hernand enemies. Here are the key tips for beating him cleanly:
- Use Turning Slash on staggers. Every time Sizlek’s poise breaks, immediately land a Turning Slash (RB+RT / R1+R2). This is your highest burst damage window. If you have Momentum socketed in your headgear, this hits for an additional 35% bonus. See our armor Abyss Gears guide for why Momentum belongs on your helmet for fights like this.
- Parry his melee attacks. Sizlek’s attacks are parriable. Landing parries fills his stagger bar fast and stuns him for combo follow-ups. Use Block (LB/L1) + Heavy Attack (RT/R2) to parry. Our parry, counter, and dodge guide covers the timing if you’re new to it.
- Watch his lightning attacks. Sizlek uses electrically charged strikes that deal high damage and can interrupt your combo. Dodge through these rather than blocking — some carry enough force to break your guard anyway.
- Use Focused Force Palm for mechanics. The Bloodied Sanctum leading up to Sizlek has environmental elements that require Focused Force Palm. Have it ready and know how to use it before the fight escalates.
- Keep food topped up. Sizlek hits hard enough that you don’t want to wait until you’re low to eat. Use food proactively between attack windows, not reactively after you’ve been hit.
- Bring Palmar Pills as insurance. If you go down near the end of the fight, a Palmar Pill lets you revive on the spot and continue rather than losing your progress.

What You Get for Beating Sizlek — All Rewards
Defeating Sizlek the Insatiable rewards you with three items plus a Contribution bonus:
- Lightningblade of Greed — Rare one-handed sword, base Attack 10, built-in Critical Rate bonus. Does not deal lightning damage in your hands. Cosmetically striking; practically a solid crit sword.
- Goldbranch Plate Crown — A helmet piece with Storm Fang already embedded in it. Take this to any Witch and extract Storm Fang from it, then re-slot it into whichever armor piece you want.
- Shadow Gloves — A consumable item that lets you steal from NPCs without being caught for one full minute. Very useful if you’re working on pickpocketing missions. See our pickpocketing guide for when and how to use this.
- Hernandian Contribution x100 — Contribution points toward the Hernand faction, useful for faction reputation and unlocking further rewards.
How to Extract and Use Storm Fang
When you receive the Goldbranch Plate Crown, Storm Fang is already socketed inside it. You don’t have to equip the crown. To move Storm Fang to a different armor piece, follow these steps:
- Go to any Witch — Bari in Pailune is close and convenient. See all Witch locations if you need the nearest one.
- Select Extract Abyss Gear from the Witch’s menu.
- Choose the Goldbranch Plate Crown and extract Storm Fang from it.
- Now select Embed Abyss Gear and slot Storm Fang into your preferred armor piece.
- If your armor piece doesn’t have an open socket, use Create Socket first to unlock one by paying Silver.
Remember: Storm Fang is armor-only. It will not appear as an option for weapon sockets. Choose a chest, gloves, or boots slot for it — those hold 2–3 sockets each, giving you space to pair it alongside other gears like Gourmet III or Aegis III.
How to Unlock Lightning for Storm Fang
Storm Fang requires Lightning Lv 1 to activate. If you haven’t unlocked the Lightning element yet, the gear will sit in your socket doing nothing. Lightning is unlocked through a chain of Abyss puzzles in Chapter 4 that culminates at the Courtyard of Precision.
The progression goes through the Spire of the Stars quest in Chapter 4, then into a series of Abyss puzzle areas including the Sanctorum of Insight, Secret Garden, and Vault of Vengeance, before reaching the Courtyard of Precision where you obtain Lightning Surge and the Lightning element. Our full guide on how to get Lightning Surge and unlock the Courtyard of Precision covers every step. Also see the Vault of Vengeance Abyss puzzle guide if you get stuck on the way.
Once you have Lightning Lv 1, activate it through your Imbue Element skill (which requires Imbue Element Lv 1 from the skill tree). With both active, every imbued attack will trigger Storm Fang’s chain lightning, arcing between nearby targets and dealing bonus AoE damage on top of your normal attack output. For how Imbue Element works in practice, see our elemental attacks and imbue elements guide.
Is the Lightningblade of Greed Worth It?
The Lightningblade of Greed is a good one-handed sword, but it won’t change your build dramatically on its own. Its Critical Rate stat is genuinely useful, especially if you’re building toward a Critical Rate boss build and stacking Insight III Abyss Gears on your weapons. Combined with those, the sword makes near-every hit a critical strike.
If you want it to feel like a real lightning weapon, you’ll need to supplement it with Storm Fang in your armor and the Lightning element active. That combination gives it the visual and mechanical identity you’d expect — regular attacks won’t shock anyone, but every imbued Turning Slash will send chain lightning arcing through enemy groups.
The Lightningblade pairs naturally with dual-wield setups. Use it as your off-hand sword alongside a heavier main-hand for crit generation while your weapon Abyss Gears — Crow’s Pursuit, Shadow Claw, Groundsurge — do the heavy lifting on the main weapon. Check our Best Weapon Abyss Gears guide for the full dual-wield socket setup. Also see how to dual wield in Crimson Desert if you haven’t set it up yet.
Is Storm Fang Worth Getting?
Yes — Storm Fang is one of the strongest elemental armor Abyss Gears in the game for any build that uses Lightning Imbue. The chain lightning effect adds real AoE damage and stagger to group fights without requiring any extra input from you. You just activate Lightning Imbue and every attack does it automatically.
It works best in high-density enemy areas and faction quest fights where multiple enemies cluster together. For bosses, the chain effect is less impactful (there’s nothing to chain to), but the base lightning bolt still deals bonus damage on every imbued hit. If your build uses elemental attacks at all — and most mid-to-late game builds do — Storm Fang is an easy slot into your chest or gloves that adds consistent extra damage for free.
To round out your elemental build fully, also look at the Storm Veil (Wind Element) guide and the Frost Mantle guide for more elemental Abyss Gear options across different elements.

Final Thoughts
The Sizlek quest chain is a grind, but it’s the kind of grind that rewards you for doing the game properly — clearing faction quests, exploring Hernand fully, and engaging with the regional story. Once you finally reach the Ruined Chapel and take him down, you walk away with two permanent rewards: a solid Critical Rate sword and one of the game’s best lightning Abyss Gears.
Just don’t go in expecting the Lightningblade of Greed to shoot lightning out of the box. It won’t. The real prize is Storm Fang — and once you have Lightning Imbue unlocked and slotted with Storm Fang active, you’ll understand immediately why it was worth the journey.
