Resin spending tips for starting out:

- Leylines (exp books and mora especially) are always good because you will burn through these like crazy while building characters
- Ascension mats for weapons you're using (from domains) and characters (from open world bosses) to keep them up to date. It's a good idea to prefarm these to get ahead of your next tier of rank ups - some of the difficulty spikes are pretty brutal if you're behind, and some of the world bosses require specific strategies/elements you may not have ready to go
- Talent books to max out your DPS unit skills and any important support skills (eg if you have a healer, level their healing talent, you can ignore their basic attack). These are like Traces but unlike Star Rail they are not nearly as scarce. You do not need to prefarm these, just go to your current tier.
- Weekly bosses with the discount are pretty good value for resource drops (shards and artifacts, rare chance for a weapon etc.) and you will eventually need the boss mats. After your discounts are done they're still ok value but not necessary. (Also do the Amber and Razor quests if you haven't, a weekly boss is hidden behind there. When you unlock 5* story quests, all of the Archons stories besides Venti also lead to weeklies)
- Under NO circumstances should you spend resin on artifact domains until you are high enough AR to do the highest difficulty, besides maybe one for the book requirement. You can get by just with random artifacts from chests until then
