Rolling for E2S1 Firefly with 276 + 20 rolls
I had 276 pulls (about 20 more after these initial rolls) and got FF super early winning 50/50, then got her lightcone 50/50, no pity on either. Then got another FF 50/50. Then lost 50/50 to gepard before getting FF to E2S1.
I prioritized her LC because her second best is on jingliu and I wasn't guaranteed to get E2. So I wanted to play it safe, make sure FF gets her own LC without needing to swap. LC also is a bigger upgrade than E1 but less than E2 which wasn't guaranteed.
