So i have been targeting Elsie's Rifle for a while now. Recently I decided to start running onslaught to get a repulser brace destabilizing rounds roll. I'm not too particularly worried about the barrel or magazine, just interested in destabilizing rounds and repulsor brace. With 7 perks in each column, that's a 1:49 chance. In the last 2.5 weeks, I have run onslaught 24 times. Mostly on normal, but around 6 of them were on expert. 18x6 (1 chest for first 4 bosses + 2 on the last boss)=108 chances from normal games. 6x11 (2 chests per boss +3 from last boss on expert)=66 chances from expert. 174 chances at elsie's rifle is what i have had from my 24 runs (given or take). Obviously I didn't get an elsie's rifle from every chest, but I'd say I have gotten at least 130 elsie's rifles in the past 2.5 weeks. Not. One. Repulse destab roll. Now, I know it is rng, but I know for a fact that at LEAST 5 of the rolls I got were under-over kill clip, and I know that because 4 of those came from 1 run. I'm going to continue running onslaught until I get the roll im looking for, and I'll post exactly how many Elsie's rifles i have once that roll arrives, but im not expecting it to be a low number.
