-For max speedrunning, once you hear the 'ding' from your last Eidolon shot AFTER lures have attached onto it, use archwing to get to gate, wait for lures that followed you to drop the shards, suck them in with [Itzal] archwing ability 3 & extract (it's fastest if only squad host exits to restart Konzu bounty & the rest wait at gate (between Cetus & Plains).
-The ideal weapon is Eidolon Rubico Prime (https://overframe.gg/build/497529/).
-Make sure to swap from something else to Rubico before shooting to gain the bonus from Vigorous Swap.
-Bring an armor stripping [Vastilok] ([Shattering Impact] & max attack speed mods) to armor strip all metallic limbs (synovias) simultaneously by shooting the Eidolon anywhere.

BUILD DETAILS
-Rank 4 [Adaptation] is the highest you can go for speedrunning so that all its stacks wear off when you get to the gate (otherwise reaching extraction with any stacks bugs all your following runs making [Adaptation] useless until you go to Orbiter & return even if it still shows on buff bar).
