If you just need 165 more fireworks, the farming stage of choice probably won't matter, as long as you're comfy with it and it's a Phase 2 stage.

If you want to further improve Mirabilis' skill level and slots, a combo run of E-5 + beginner bonus stage is what I'd go for to reach the desired amount quicker (especially when your level and party strength is taken into account), purely for having the best combined ratio of 0.95 fireworks/stamina. (There's a guide from Discord pinned at the beginning of this thread.)

While E-5 and E-6 share the same ratio of 0.53 and offer the same Secret Garden, you might ask why E-5 instead of E-6. The key is getting that Secret Garden to trigger as many times as you can, and because the stamina cost of E-5 is half of E-6, you can have twice the attempts in triggering it. (extra tip: don't share or attack the first raid boss that comes out of it, so you'll only get the Secret Garden)

For every 80 stamina, you'd get up to 76 fireworks with the combo above [(8+30)*2] compared to 43 in a single E-8 run.
