Yes that should work need about 5-10 or higher, but it's best to choose senior if you have it. Reason why is because the base (purple) is rank 30 while the other two (nether and formal are rank 29) so using it on senior works better because you already have a good start on the base jump that senior gives you.

If not get Junior and lvl it up a bit to 5 or higher. Its not hard to get at all compared to senior.

Nothing is 100% i always use a 3-5 ratio. Meaning if i have enough material i try making 3 or 5 of the same things that way even if 2-4 fails i get 1 or if i'm lucky i may get all, or all may fail.. since alchemy can be creul like that. So try making 2 or more of a product. If it succeeds then it's yours to keep. If you are lucky and happen to get extra then just give it to an alt or sell it. And remember even if you fail its never a fail. You can use the "fail" to try and rank up and make it again or you can keep the "fail" to wear or use for another recipe or just sell it.

-.- geh i forgot what else i was going to say... but thats about the gist of it.
