Update 6 in Roblox Anime Crusaders quietly added one of the most interesting secret units so far. The Undead Knight (also known as the Undead King) doesn’t show up in normal grinding routes, and many players miss it simply because they don’t know where to start. The good news is that once you understand the method, getting this unit is actually much easier than expected compared to older secret units. Here’s a complete breakdown of how to unlock the Undead Knight, along with tips to make the grind faster and more consistent.
Step 1 – Get Access to King’s Portal
The first thing you need is a King’s Portal, which is the only way to encounter the Undead Knight. This portal is different from regular ones and acts as a special stage tied to the secret unit.
Once you enter the portal, you’ll notice a few key details:
- You only have 10 lives, so mistakes matter more
- The stage runs for 15 waves, making it shorter than most modes
- Rewards shown include items like Egg Sacrifice and Dead Tokens, not the unit itself
This can feel confusing at first since the unit isn’t listed as a reward. However, the Undead Knight is actually a hidden drop tied to completing the portal, not something displayed upfront.
Step 2 – Clear the Portal Efficiently
The King’s Portal is surprisingly manageable compared to other high-end content. The difficulty mainly depends on your setup and how you handle early waves.
A solid strategy is to focus on farming early and scaling later:
- Spend the early waves (around wave 1–9) upgrading your economy
- Start placing your main damage units after wave 9
- Fully upgrade your core units before the final wave
Around mid to late waves, you’ll also notice multiple enemy paths spawning, which increases pressure. This is where strong AoE units and proper placement matter the most.
Units like:
- Satoru Gojo
- Enrico Pucci
- Sukuna
are especially effective due to their scaling and crowd control. If you already have meta units, this portal becomes much easier to handle.
Step 3 – Defeat the Undead King Boss
At the final wave, the boss Undead King will appear. This is the key moment that determines whether you get the secret unit.
Compared to other portal bosses, this one is actually more forgiving:
- Around 26.5 million HP, which is lower than older portal bosses
- Additional enemies like Berserk units may spawn with high HP
- The boss can use abilities, but can be controlled with proper damage and stuns
Because of the lower HP pool, this boss is much more doable even without perfect setups. In fact, with strong units, some players can even consider attempting it solo.
Step 4 – Unlock the Undead Knight (Secret Drop)
Once you defeat the boss, you have a chance to receive the Undead Knight directly as a reward. This is not guaranteed every run, but it can drop without needing a pity system if you’re lucky.
When you get it, you’ll notice:
- It’s marked as a secret unit
- Only a limited number of players may have it early on
- It may initially appear “on hold” before you can fully manage it
This makes it one of the more exclusive units in the current update.
Step 5 – Evolve the Undead Knight
Getting the unit is only the first step. To unlock its full potential, you’ll need to evolve it.
Here’s what you need:
- 5,000 takedowns using the unit
- A crafted item called Sword of the King
The Sword of the King requires farming materials (around 75 pieces needed for crafting), so expect some grinding here. This part takes longer than obtaining the unit itself, but it’s necessary if you want to maximize its strength.
Tips to Make the Grind Easier
Grinding for a secret unit can feel repetitive, so optimizing your runs helps a lot.
Focus on using strong late-game units that scale well, especially ones with AoE or crowd control. Prioritize economy early so you can fully upgrade before the boss wave. Also, keep your runs consistent rather than rushing, since survival matters more than speed in this mode.
If possible, play with a coordinated team. Even though the portal is easier than older content, having backup damage and support makes runs safer and more reliable.
The Undead Knight in Anime Crusaders Update 6 is one of the more accessible secret units, but only if you know where to look. King’s Portal is the key, and once you get comfortable clearing it, farming the unit becomes much more manageable. If you’re aiming to improve your team or collect rare units, this is definitely worth your time. Just focus on clean runs, build a strong setup, and be ready to grind a bit for the evolution materials afterward.
