I dont think so. Secret lies in the scoreboard on wipe. We beat Templars scoreboard objective by making the fight harder. When you skillfully block all his teleports and kill all those minotaur, you get the conditional chest from scoreboard. We get through Gorgons to the chest room without being spotted, we get the chest from the scoreboard. Spotted but Gorgon killed to continue, chest door closes on exotic door chest and shard chest. Atheons scoreboard might suggest killing Atheon without supplicant kills OR times vengeance. Again like the Templar chest, make the fight hard, possibly get a reward. When you book through the time gates without shooting Oracles you do much less damage but Atheon is frozen. Black Hammers allow a team to wreck his critical spot nonstop. Supplicants can be made to blow themselves up when you run by without pausing.
