Hey guys, I explored act 5 100% a month ago, and yesterday night I became Cavalier. I didn't expect to do it on my first attempt with just 500 units but I passed the test. Anyways, now I am a little puzzled as to what content to focus on next. I have Variant #1 and labyrinth of legends yet to be attempted, completed variant #2. Would appreciate your advice.
