Unless your team plans to unload all Gjallarhorn on atheon at once, it's best to not be used. I would advise icebreaker or super good advice in place of gjallarhorn. For primary, Atheons epilogue is good for oracles, unless you have found verdict or praetorian foil, then use VoC. Fast charging fusions are good for oracles if you don't have found verdict or praetorian foil. If you are using atheons epilogue, use icebreaker for sure. It does massive damage on atheon and the ammo regen is nice so You don't have to about reloading. However, if you are good at hitting criticals on atheon, I advise the black hammer. Fatebringer is best avoided due to the fact that it has a hard time with oracles. Heavy is all on preference, though Super Good Advise is the best to use (if using an exotic heavy). Corrective measure should be your best choice as it can hold a lot of ammo and destroys oracles very quickly. Rockets are best unused as they tend to be an easy suicide. Overall here are the best setups depending on your roll: Set 1: [i]Oracle Killers[/i] 1. •atheons epilogue/VoC •found verdict/praetorian foil •super good advise Set 2: [i]Atheon Slayer[/i] 1. •VoC •Black hammer (or icebreaker if used with legendary heavy) •Super Good Advise/Thunderlord (or Corrective measure of using icebreaker) The overall best for both rolls would be •Atheon's Epilogue (the oracle killer) •Icebreaker (the atheon slayer) •Corrective Measure (both atheon and oracle destroyer)
