The Kenpachi Zaraki unit in Anime Expeditions is officially called 8th Sword, and it sits behind one of the game’s hardest grinds. It only drops from Spirit City Raid Act 3, carries Unbound rarity, and becomes a genuine raid carry once you evolve it into 8th Sword (Berserk). Getting it takes patience, but the path is fixed and predictable.
Quick answer: Clear Spirit City Raid Act 3 to roll for 8th Sword. The drop rate is 0.1% on Normal and 1% on Hard. Once it drops, evolve it with 20 Red, 20 Blue, 20 Green, and 3 Rainbow Sprites plus 10,000 Gold to unlock 8th Sword (Berserk).
8th Sword unit overview and stats
8th Sword is a Physical, AoE-focused DPS unit built around constant pressure. It applies aura damage, cleanses stun, throws follow-up hits, and can enter a temporary Berserk state. It is not a banner pull, so summoning has no bearing here. The only reliable route is the raid.

How to get 8th Sword from Spirit City Raid Act 3
8th Sword only comes from clearing Act 3 of the Spirit City Raid, where the boss is the Berserker. Act 3 is the hardest stage in the raid, so newer accounts should not expect a clean solo run without strong units. You can launch the game from its Roblox experience page.
The drop chance depends on difficulty, and the same run can also yield useful gear on the Hard bonus.
| Difficulty | Drop | Notes |
|---|---|---|
| Normal | 0.1% 8th Sword | Extremely rare; expect a long grind |
| Hard | 1% 8th Sword | Better odds, but the stage is tougher |
| Hard bonus | 3.5% Shinigami Sword | Equipment tailored to this unit |
Hard is worth prioritizing only if you can finish runs reliably, because 1% beats 0.1% by a wide margin. The run also builds toward a 35-run pity counter, so consistent clears eventually pay out. If you cannot hold Hard together, farm Normal, materials, and stronger support units first.
Farming tips for the raid
| Tip | Why it helps |
|---|---|
| Run with other players | Spreads out enemy pressure and steadies clears |
| Place units farther back | Handles waves before enemies leak |
| Bring support units | Buffs and slows stabilize dangerous waves |
| Use raid totems when available | Damage boosts speed up repeated clears |
| Farm Hard once you can clear it | 1% is dramatically better than 0.1% |
Solo Spirit City Act 3 with one DPS unit
Act 3 can be soloed with a single high-damage carry backed by a farm unit for Yen. A maxed Puppet (Telekinetic) at Unbound is one proven option, but the same approach works for any DPS unit that can push through the Berserker’s scaling HP, which climbs toward roughly 881k.
You know the clear worked when the boss dies and the reward screen appears. A successful 8th Sword roll shows the Unbound unit added to your inventory at Level 1.
Evolving 8th Sword into 8th Sword (Berserk)
The base unit is strong, but 8th Sword reaches its real value only after evolution. Farm the materials ahead of time so you can evolve immediately once it drops instead of running it underpowered.
| Material | Amount |
|---|---|
| Sprite (Red) | 20 |
| Sprite (Blue) | 20 |
| Sprite (Green) | 20 |
| Sprite (Rainbow) | 3 |
| Gold | 10,000 |
Sprites are crafted from Grey Sprites, which come from Story, Challenge, and other modes. Gold comes from clears, quests, daily content, events, and selling Shiny units. Once the evolution completes, the unit becomes 8th Sword (Berserk) with its full passive kit active.
8th Sword (Berserk) passives
The passive kit is the reason this unit is worth the grind. It combines aura damage, follow-up attacks, stun immunity, and a timed Berserk boost, which makes it effective against both dense waves and single tanky targets.
| Passive | Effect |
|---|---|
| Demonic Presence | Enemies within 40% of its range take 5% of its current damage every second |
| Savage Rebound | Cleanses stun and fires a 100% damage follow-up attack |
| Dismemberer’s Rush | Triggers a 100% damage follow-up when an enemy in range drops below 10% HP |
| The Nameless Demon | After 25 takedowns, enters Berserk for 15 seconds |
| Berserk State | +20% damage, -10% SPA, attacks apply Dismembered |
Demonic Presence pays off just by keeping enemies inside part of the range, while Dismemberer’s Rush shines against bosses and high-HP enemies that live long enough to hit the 10% trigger.
Best trait, equipment, and placement
For traits, high-end damage rolls matter most. Unbound is the dream target because it pushes an already strong damage profile higher, while Primordial is a solid alternative depending on placement count and team setup.
| Build choice | Recommendation |
|---|---|
| Best trait target | Unbound |
| Strong alternative | Primordial |
| Best equipment | Shinigami Sword |
| Best role | AoE DPS / raid carry |
| Best mode fit | Raid, Challenge, hard wave content |
The Shinigami Sword is built around this playstyle and drops from Hard Act 3, so you may pick it up naturally while farming for the unit itself. It is not required to obtain 8th Sword, but it is the recommended gear.
For placement, put the unit where its range covers the most enemy pathing so its aura and AoE keep enemies inside the circle longer.
- Curves and loops where enemies stay in range
- Mid-to-late path positions for safer wave control
- Spots supported by buffs or slows
- Areas where bosses are forced to travel through its circle
Avoid placing it too close to spawn unless your team can delete waves fast. In harder raids, a backline position is usually safer because it gives you more time to scale.
8th Sword is a late-game investment. If you can clear Spirit City Act 3 reliably, its aura damage, follow-up hits, stun cleanse, and Berserk state make it one of the strongest raid carries and a natural way to make future raid farming easier. If you cannot hold Hard yet, build up materials, gems, and support units first, then commit to the grind once the 1% drop is within reach.
