The easiest method to create the Quality 60 Demolition Bombs is by adding a high Quality Bomb to the recipe. This quest is extremely similar to Abelheim Manor, part 2.

Here are the requirements you should meet before proceeding:

1. Synthesize high Quality Green Neutralizers: In order to synthesize a high Quality Bomb, you will need Green Neutralizers.
2. Create a high Quality Bomb: Use the Green Neutralizers to level up the Bomb’s Quality loop.

Creating Green Neutralizers

Start off by creating the Green Neutralizers.

Insert a Plant-type ingredient in the Effect 1 loop. 

At Wind Element level 14, this loop will activate the “Synth Quality +12” effect. When used in a recipe, this Green Neutralizer will add 12 Quality to the synthesis.

Next, level up the Quality loop, which requires Lumber-type ingredients. At Ice Element level 6, this loop adds 30 Quality to the Green Neutralizer.

You can also level up the Traits loop, which will also require Plant-type ingredients. 

This loop will let you pick traits like “Quality +”, “Best Quality” and “High Quality”. These traits can be transferred to the Bomb and the Demolition Bomb later.

Add a Water-type ingredient to the Effect 2 loop, then complete the synthesis. Make sure to pick up any Quality-boosting traits if available.

You will then obtain multiple high Quality Green Neutralizers with Quality-boosting effects and traits.

Synthesizing the Bomb

Select the Bomb recipe from the cauldron’s menu.

Start by inserting a Crimson Ore in the Effect 2 loop.

Add a Fuel-type ingredient to the Traits loop.

Insert a Sand-type ingredient in the Effect 3 loop. At Fire Element level 2, you will unlock the Quality loop.

Add the Green Neutralizers to the Quality loop. At Wind Element Level 6, this loop adds 30 Quality to the recipe. Each Green Neutralizer you use will also add Synth Quality +12.

Synthesize the Bomb, and pick up the Quality-boosting traits if available.

Creating the Demolition Bombs

You can now synthesize the Demolition Bombs.

Insert the Bomb you’ve just synthesized in the Quality loop. At Fire Element level 2, this loop adds 20 Quality.

Insert a Fuel-type ingredient in the Traits loop. The Demolition Bombs will easily clear the minimum Quality requirement.

If you fail to meet the 60 Quality requirement, synthesize a second high Quality Bomb.

Synthesize the recipe. Again, remember to pick up the Quality-boosting traits.

The recipe will automatically synthesize three Demolition Bombs. 

Head over to the Weisheit Academy District  and take the Demolition Bombs to Volker. You will find him inside Abelheim Manor.
