Most Broken Venom Injection Build for Ultimate Freyna | Venom Baptism vs All Solo Hard Bosses | TFD

Use Firing Fiesta on Swamp Walker to 1 phase. I tried with SPS but ended up getting 15 seconds with it entering immunity phase. Firing Fiesta is more consistent with 1 phasing bosses if you don't mind the 1-2 second difference. All fights I used SPS btw. Swamp Walker was the only fight I used FF.
