[3.13] Devon's Impale Barrage-RoA/TS/SA Deadeye | All content viable | 3.5mil+ DPS

Any tips for 3.14? I'm lvl 86 in the current Ultimatum league but I'm getting oneshot too often in the higher tier Atlas Maps. For sure I'm doing something wrong. I have some experience with this build from the previous Ritual League but late game seems way harder nowadays. I love this build and I'm commited to make it work. I play solo btw.
