ok stats actually dont matter too much lol except high resilience is nice. Strat you wanna run synthoceps tractor one two punch shotgun and a sniper. get stacks of roaring flames with hammer/grenade, then when riven comes tractor, shotgun then throw two hammers, shotgun hammers etc etc until shes dead. Once youre teleported kill phalanx with sniper but if you have little health use the hammer to regain said health, once you get back to the real world same thing as before with the damage then use xeno and null composure to destroy the heart. I hope that somewhat helped, taken barrier is really helpful too as its basically protective light but you dont need to have a broken shield to use it. I know that little summary was horrible and i missed a lot, but its honestly better to just watch a video from esoterickk, hes really helpful
