Warriors don't have have their own spell circles, but they do have access to minor spiritual and minor elemental spell circles that are shared among a few professions. It is very expensive in training points though, most would not advise learning any (or more than a couple) before level 100 cap. It is more of a postcap or far postcap goal without gimping your warrior in other core areas.
