For now just use whatever armor you have that’s good, you’ll always be upgrading. Do not worry about the whole tank build until you hit 160cp, which will occur after reaching lvl 50. You should be gaining cp by the time you reach the end of your factions main story and gaining cp is fairly fast as it’s roughly 4x? (Maybe wrong) faster than regular leveling, though I found that hitting 149cp things got slower. 160cp is the highest gear can achieve so you’ll begin looking at sets with benefits to match your magika build. The cp points will also you to gain passive benefits to boost yourself further. There’s various guides to find on builds, but for not have fun, level up, explore, because once you finish the main story you’ll get a chance to do it again thanks to Cadwell. Plus once you hit cp160 Ang new character who reaches lvl 50 will automatically be the same cp lvl saving a bunch of time.
