Weak Legacy 2: Blood Manipulation Rework Guide

Updated: November 18, 2025  ·  Reading time: ~5 min

A complete walkthrough to unlock the rework, level mastery, farm the sickles, unlock both secret passives, and obtain the ultimate

Blood Manipulation got a full rework in Weak Legacy 2, and honestly, it is one of the most enjoyable and rewarding progressions I have gone through in a while.

When the update dropped, I ran through the entire unlock process in one sitting, and this guide walks you through the exact progression in a straightforward way.

If you are starting from zero, this covers training, leveling mastery, farming the sickles, understanding both secret passives, and unlocking the ultimate while avoiding the mistakes I made along the way.

If you want the full experience without confusion, you will find everything here step by step.

Getting the Blood Manipulation Rework

Your first stop is the Demon Cave located near the Mugen Train Station.

This is where the Blood Manipulation trainer lives, and you are looking specifically for Guaro. When I did this before the update, the skill layout looked slightly different, but the requirements and the process are still the same.

You only need two things to start the quest. Level fifteen and ten Ken. If you meet both, speak to Guaro and accept the Blood Manipulation quest.

From here, you have to take out twenty five Demon Slayers. Nothing fancy about this part. Just pure farming.

I remember speeding through this because it can feel a little repetitive, but once you finish the last kill, the reward pops instantly and you get the reworked Blood Manipulation.

Now comes the important part, because unlocking the skills is only half the journey. To get the full kit, especially the ultimate, you need mastery.

Leveling Blood Manipulation to Mastery 120

Your target is mastery one hundred twenty. That is the point where your ultimate unlocks. From personal experience, there is no quicker way than farming Yahaba.

You only need around four or five Yahaba kills to hit the one hundred twenty mark.

What makes Yahaba the most efficient option is how quickly you can cycle the kills compared to other bosses.

I have tried experimenting with alternatives, but nothing came close to the speed you get here.

Once you hit mastery one hundred twenty, the fun really begins because now you can start hunting for the new passives and the ultimate skill itself.

Farming the Sickle and the Ultimate

The Sickle unlocks one of the two secret passives for Blood Manipulation. To start farming it, travel from Mugen Train Station toward the second village. Outside the village you will find Gotro. That is the boss you need.

He drops two things you need. The Sickle passive and the Blood Scythe Reap ultimate.

Both are rare, so expect a bit of farming. For me it took roughly twenty minutes to get both drops, but your luck may vary. Try to stay focused on consistent cycles, because this is one of those farms where walking away for a few minutes can mess up your flow.

Once you have the Sickle and the ultimate, you can finally experience the full Blood Manipulation kit. And yes, this is where the rework shines.

Understanding the First Secret Passive

Sickle Passive

The first secret passive gives your Blood Manipulation abilities a poison effect. It does not affect your M1s. It only activates through Blood Manipulation skills.

Every time you use an ability, there is a chance to proc the poison effect.

When it procs, the damage over time is genuinely impressive. The visual effect looks great too, with the purple poison coating the target before the damage ticks start rolling.

When I tested it on training dummies, I saw consistent ticks reaching around one hundred damage, sometimes higher depending on stats. For a passive tied to your ability kit, it adds a lot of value during fights.

This passive instantly makes your combo rotations feel heavier and more punishing.

It is also very noticeable when fighting bosses because the DOT stacks save you time when you are forced to reposition.

Understanding the Second Secret Passive

Blood Death Passive

This one caused a lot of confusion when the update launched. Some players thought it would revive you when you die. That is not what it does.

Blood Death triggers an explosion the moment you die. It is not revival. It is pure retaliation damage. Think of it as a massive final goodbye.

When I tested this, I reset my character next to an NPC just to see how much damage it outputs. The explosion is ridiculous. One explosion took half the NPCs health in a single hit.

When I repeated it in a group, the explosion wiped the entire cluster instantly.

This passive is more situational than the Sickle poison, but when it activates, the value is massive. It will surprise a lot of players in PvP and clean up clustered mobs in PvE.

Blood Scythe Reap Ultimate

Your ultimate is the Blood Scythe Reap, and it looks as destructive as it sounds. With mastery one hundred twenty and the drop unlocked, the ability turns your rotation into something much more aggressive.

The animation is dramatic, the damage is high, and the timing is perfect for finishing bosses.

I tested the ultimate several times on the Gotro boss, and the burst feels extremely satisfying.

It is one of those ultimates that rewards timing rather than spamming, and fits perfectly with the rest of the Blood Manipulation kit.

Unlocking the rework does not take long, but getting the full value out of it requires proper farming and a clear plan. From my own playthrough, the smoothest path looks like this:

  • Train with Guaro
  • Level mastery at Yahaba
  • Farm Gotro for the Sickle and the Ultimate
  • Learn how both passives work
  • Practice timing with the new ultimate

Once you complete each step, the Blood Manipulation kit feels complete. You get poison damage that destroys bosses, a high value explosion passive for death trades, and a clean ultimate that gives the entire style a sense of finishing power.

If you combine both passives with strong mastery, you get one of the most satisfying progression paths Weak Legacy 2 has right now.
