A globetrotting riddle, with a twist

Question

_{This is an entry into Fortnightly Topic Challenge #36: Twisted Classics 1. First time doing an FTC, so let me know what you think.}

Let's take a little trip around the world, shall we? Make sure to write me when you get there!

My first's in Rhode Island and certainly in Greece
My second's in Gotthard, Odisha holds this piece
My third's in Bethlehem or Deseret I vow
My fourth is in Bahrain, and living with the Miao
My fifth's in Savannah, mixed with the Cherokee
My sixth is in Bismarck, hidden among the Cree
My seventh's in Vineyard; at home in Morocco
My eighth's in Bar Harbor, and mingling with the Ho

Put them all together and I hope you will see
To answer this riddle, what will you have to be?

Answer 1

The trick to this is that

we're not extracting letters common to each pair of words, as you'd usually do in these types of puzzles. Instead, the second in each pair hints at a writing system of some sort, and the first has a letter in it. For instance, "in Greece" tells us that we're looking for a Greek letter, and right at the start we have Rhode Island.

The letters you get from each line are

Rhode Island (Greek alphabet)
Gotthard (Odia alphabet)
Bethlehem (Deseret Alphabet)
Bahrain (Pollard Miao)
Savannah (Cherokee Syllabary)
Bismarck (Cree Syllabary)
Vineyard (Tifinagh)
Bar Harbor (Warang Citi, Ho language)

These letters, when put together, clearly spell out our answer:

You need to be a POLYGLOT!
