Revision 4

Overview

The Kuku Bismuth Spear is a reinforced two-handed weapon in Crimson Desert that applies bismuth buildup on every hit, slowing targets and increasing damage dealt to them. It is crafted at the Kilnden Workshop by reinforcing a Bismuth Spear with Kuku Iron Pot components. Like all Kuku weapons, it will never break once reinforced and supports further refinement.

The bismuth effect is widely considered the strongest of the three Kuku spear variants for boss encounters. The slow effect gives Kliff more breathing room to dodge and reposition, while the damage increase against slowed targets means each subsequent hit deals progressively more. Even without upgrades and at a lower level than the player's main weapon, the Kuku Bismuth Spear can out-damage fully enhanced alternatives against tough opponents.

How to Obtain

Step 1: Unlock the Blueprint

Complete the required sanctum in the witch quest line. The Kuku Bismuth Spear blueprint becomes available at Grimnir's Kuku Shop after clearing the corresponding sanctum. Players who have completed all sanctums will have this blueprint unlocked automatically.

Step 2: Obtain the Bismuth Spear

The base Bismuth Spear is found at the Well of Enlightenment, located slightly south of the Four Breakers Barons near the Crimson Desert region. Descend into the ruined building and collect the spear from inside. Watch out for nearby enemies; either defeat them first or wait for them to move away before picking it up.

Warning: Do not use the base Bismuth Spear before reinforcing it. Like all unreinforced Kuku base weapons, it will break after a few hits and be lost permanently.

Step 3: Gather Crafting Materials

The crafting cost for the Kuku Bismuth Spear is relatively low compared to the other variants. You need small batteries (from robotic enemies) and bismuth ore, which is abundant in the same area where the base spear is found. The region around the Well of Enlightenment has plenty of bismuth ore deposits.

Step 4: Craft at Kilnden Workshop

Bring all materials to Grimnir at the Kilnden Workshop. Craft the Kuku Spear as an intermediate component, then combine everything to create the Kuku Bismuth Spear.

Combat Performance

The bismuth buildup mechanic works in two stages. First, each hit applies a slow debuff that reduces the target's movement and attack speed. Second, once the bismuth status is fully applied, damage dealt to the slowed target is significantly increased. This double benefit makes the weapon devastating against bosses.

In testing, the Kuku Bismuth Spear at a lower level and with no upgrades dealt more damage per hit against a boss than a fully upgraded main weapon with five Abyss Gear effects. The slow effect also creates openings to dodge boss attacks that would otherwise be too fast to react to.

Surprisingly, the bismuth variant also outperforms the Kuku Lightning Spear against robotic enemies. The bismuth buildup deals enough bonus damage to compensate for the lack of a lightning weakness exploit, while also slowing the robots significantly.

Tips

• The best Kuku spear variant for boss fights due to the slow plus damage increase combo.

• Even unupgraded, it can out-damage higher-level weapons on slowed targets.

• Bismuth ore is plentiful near the Well of Enlightenment, making the crafting cost minimal.

• Pair with aggressive playstyles; the slow effect gives extra dodge windows against fast bosses.

• Consider refining this weapon to maximum level to further amplify its already strong damage output.
