How do I obtain a bottle of each Raubritter Lager and what are their effects?

Question

There are three variations of Raubritter Lager which are supposed to have some fairly potent effects. How can I obtain them and what do they do for us?

Answer 1

You can obtain by dropping form the Raubritters and also by open chests in the isle of Ada

To create the enchanted Lager you need to use a night harpy beak in Millstone and use it in the lager.

Both of them increases you defense against the nighty harpy

Nobody found a way to obtain the cool Raubritter Lager so far
