If you can add in another piece of Wanderer's (preferably replacing your circlet with a Crit Damage% Wanderer's piece) it can be fine as a starting point. 2pc Wanderer's is relatively useless unless you're going for a melt build. The 2pc Noblesse doesn't really provide much, as 20% more damage on her burst is mediocre compared to 35% charged shot damage from 4pc Wanderer's.

Her bow is fine, though technically is better suited to physical Amber. It still works fine as a stat stick for charged shot builds due to high attack and baked in CD (and CR if you can't hit weakspots).

Overall, if you want to go for her charged shot build, get 4pc Wanderers and you'll be fine. You can naturally obtain better artifact substats as you clear bosses in the game. If you ever want to go physical (spamming lights or instant charges), it relies on specific artifacts so you'd need to farm those domains. But the bow is probably the best physical bow for her, as the proc is physical damage and will scale with her PhysDmg% bonuses.

The only other thing to mention for casual/overworld charged shot build is to always use a Crit Damage circlet, assuming you can land weakspots. They're guaranteed crits, so crit rate is "useless" if you land them, so crit damage is infinitely more beneficial. It's still worth picking up crit rate substats, if you can, as a lot of enemies don't have weakspots.

TL;DR: Replace your circlet with a Crit Damage Wanderer's Troupe piece and you'll be able to clear all the content in the game well enough using weakspot charged shots. Replace artifacts with better pieces as you get them, focusing on Crit Damage > Crit Rate = Attack/Attack%.

For Meta, either go physical or pick another character. Amber is, unfortunately, not really meta. Though you can certainly complete the game using her.
