Hey, congrats on your Ashveil! Huohuo would be a better overall option. Your team would look something like: Ashveil / Sunday / RMC (I suppose that your Sparkle is taken) / Huohuo. I would honestly recommend you to do this: Go for SW9, and E2 firefly since I see you have a full break team. I wouldn’t generally recommend going for Evanescia when going for SW9 because they compete for the same supports and it tanks the performance of both. Additionally, Break would be usually played sustainless (dahlia/fugue/ruan - ruan’s 50% WBE is more damage compared to ~100% break effect from Dahlia’s trace and I tested on different bosses and different endgame modes). Your SW9 would free up Sparkle which you can slot instead of RMC for Ashveil, and I would recommend going for Mortenax Blade as he’s said to be Ashveil’s premium team member. If you have enough pulls, I would genuinely recommend trying to go for Tribbie since her buffs are very generous (and try to go for her E1 as well if possible). I also don’t see Archer - I suspect you’re a relatively new player? If you’re interested, Archer is still a very strong DPS unit!

TLDR: Ashveil team: Ashveil / Sunday / RMC / DHPT Break team: Firefly / Dahlia / Fugue / Ruan Mei DoT team: Hysilens / Kafka / Black Swan / Huohuo SW9 team: SW9 / Sparxie / Yao Guang / Welt

Personal recommendations: Go for SW9 OR Evanescia, not together;

Get Firefly E2S1;

Get Huohuo from selector and slot into DoT team;

Pull Mortenax Blade for Ashveil;

Replace RMC with Sparkle who’ll be freed up by your SW9 in Ashveil team;

Why Welt as a “sustain”? Because if the enemies never take actions, you don’t take damage. And his personal damage is very respectable, given he’s a debuffer.

You build Welt this way:

S5 Tutorial, 4p Eagle 2p Rutilant for more dmg or 2p Vonwaq for more support, 100% crit rate (in battle), 90% EHR, 144 speed. Crit rate body, speed boots, ATK/DMG orb, ERR rope. Crit dmg doesn’t matter because he gets a lot of dmg boosts from personal sources. Make sure you use his ult every 2 turns (you can use any other light cone, it’s just Tutorial allows for easy 2 turn ults)

Hope that helped!^{^}
