Blood Transfusion system

Transfusion allows you to level up Vassals past their level cap (which will depends on how many dupes you have on a character) based on the level of your top 5 Vassals.

This makes it easy to invest resources as you only need to focus on 5 units instead of having to level up the 40+ Vassals we currently have in the game.

To access the Transfusion System, you can click the Tree Icon in your lobby

Currently there are only two options to unlock more slots on your Transfusion :

• The Observatory provides some (up to 15 slots)
• TBy spending Moon Tear directly (500 per slot)
• The third line has a 30% chance of appearing.

If you want to get your units past their level cap (*SR at 160, or SSR up to 200*), you can place them in the Transfusion, and they will automatically get to the current max level of your top five characters.

This means you only need to focus on getting 5 units to MLB (3 dupes for level 200) and as a F2P player you can focus on getting only 1 copy of the characters you like afterwards.

After level 200, you will pay resources to level everyone in the Transfusion directly. This is called Evolution and the cost goes up as you progress further into the game, so don’t worry if your progression gets slower, since that’s the same in all idle games.

You can check our Silver and Blood Comprehensive Sheet for the levelling cost.

This system is the reason players will have to stockpile Divine Blood Drops boxes and other resources so they can min-max when to level up.
