Converting Eomon Blood Samples into Melee Amps

I misunderstood what people had told me, and have heard lots of weird ideas from people about how this works.

I was desperate for a VI amp and so did it all myself by buying most of the parts and risking it.

It is a really simple mission and no reason for all the secrecy and 1/2 truths about how it works.
(not blaming anyone, just was frustrating for me figuring it out esp when I bought what I thought would give me the VI amp and it only gave me the IV)

The Mission Broker is inside the little biodome at Minopolos tp.

There are 5 different sample types. A, B, C, D, and E

Turn in any 3 different samples and you will get the I amp.

Once you have turned in a type you can not turn in anymore of that type.

Turn in a 4th type and you will get the IV amp.

Turn in a 5th type and you will get the VI amp.

Sequence does not matter, but a,b,c are the cheapest so it is logical to do them first.
D is the second most expensive so it is logical to do next.
E is the most expensive so it is logical to do it last.

The order I actually did it in:
A,B,C - got the I amp
E - got the IV amp
D - got the VI amp
