In Terraria's (v1.4.4.9 - tModLoader v2024.8.3.2) Calamity Mod (v2.0.4.4), Draedon's Exo Mechs represent one of - if not the most difficult challenge in Calamity's boss progression, tied possibly only with Supreme Calamitas. Unfortunately, in the extra tough Legendary world (Master Mode plus seed, getfixedboi), it is made even more challenging, virtually impossible with multiple GFB "bonus" changes: Draedon enters the fight, regularly firing a pulse rifer. The berserk attacks are even more aggressive, and they (almost) never end. Apollo's and Artemis' berserk phase is totally unbalanced like Boomer, requiring teleporter chaining to even have a chance. However, because Supreme Calamitas' Ashes of Annihilation are dropped out-of-order by the Calamitas Clone, defeating the Exo Mechs unlocks end-game gear for facing Supreme Calamitas.

Strategy:
The Exo Mechs are unhinged chaos. There is not an obvious pattern to the flurry of projectiles and movement, but there are a few known good ones. I start with Apollos and Artemis, the hardest to me in the GFB seed (because of their insane berserk phase), working from the top right of a world arena, carefully falling down and left, alternating working slowly (tapping flight button) back to the top in a zig-zag pattern, saving rage and adrenaline for phase 2, where I pummel Ares with the Murasama. The berserk Blender attack is outrun, and after resetting to the bottom, destroy the closest weapon while flying up and away, repeating until beaten. (Ares is the only mech, who will exit his berserk phase with insane defense and Blender attack, by outrunning and resetting him.)
Next is Thanatos, who can be easily dodged, providing a great opportunity to recharge all timers (e.g., dodge, shields, rage, adrenaline). Once sufficiently weakened, the twins will reappear, and after suffering enough damage, they will be fought alone. Their berserk attacks are impossible. I could not see a usable pattern that I could exploit. Their attacks are one-hit kills, and their movement is impossible, so I used teleporters again, out-engineering the master engineer, Draedon himself.
Lastly, the teleporters should be used to draw Thanatos and Draedon to the far side of the arena until Thanatos begins his berserk phase. When the cross-hair appears on you, warp back to the other side before Draedon catches you, and destroy Thanatos with the help of the Witch's Broom or other flying items, max damage accessories, adrenaline, rage, and the essential Dragon Rage.
