No‑webshop servers keep power out of the shop so progress comes from events, drops, and trading. Cosmetics and small utility are usually still sold, but they do not decide fights. Always read the shop list before you invest time. If it is public and short, that is a good sign.
Run the weekday events and sell extras. Use your jewels to secure wings, a solid set, and a weapon rather than chasing perfect rolls. In Siege and Arka, organized parties beat random gear spikes. The whole point is that time played equals progress earned.
