So I got arena up and running (first time playing) and I honestly have no clue how to play it.  Coming from Skyrim, it seems confusing no matter which type of character I try to play.  I try magic, I see my magicka does not regenerate.  I try a warrior, I die really easy to those stupid rats and goblins in the first dungeon.  So can someone offer some advice to me, as I have no clue what I'm doing.
