First of all, welcome to Strats!
I haven’t played ESO in a bit, but generally it’s not worthwhile to invest in gear until your CP160. For now, you can prob just use the gear that drops, or if you want to find a crafter to do a cheap training set or something of the sort. I personally when leveling alts just use the gear I find and occasionally get a new training set crafted every 20-30 levels.
Sounds like you used to play and took a break, so not sure how much you know about the leveling system. Once you hit level 50, you’re going to start gaining Champion Points. I believe you start at 10, and you get a daily boost of increased XP gain to help level. Your gear at level 50 will start to increment with your CP level. Same idea as before. So it’s truly not worth going all out and getting a nice build done until you’re CP160.
Getting nice gear for you is expensive and you’ll outgrow it fast. So once again, find someone who’s able to do some basic training gear or something else that might service you for 20-40 levels, and then upgrade again either with gear you find, or some more crafting. Don’t invest to heavily though because you’re going to need to spend a small fortune for some nice CP160 gear.
That all said, I’m not certain who in Strats is a crafter and still plays regularly. Again @Rotaugen might be able to help out there; but not sure what he’s runs tbh.
