Thought to be considered a AA you had to have at least one lvl of the prestige class but guess not

Prestige in DDO are enhancements, and not classes. An elf or half elf 18 cleric 2 monk can take elven arcane archer enhancements. An elf of half elf can be any class combination, and as long as they take the prereq feats can qualify for AA and take AA. They will want to have a blue bar to imbue arrows with, but that can be obtained many different ways.
