My take on a [Buzlok] Eidolon build, now newly updated!

This can be used as a base for those that have Rivens, or for those that are just starting out, or even for those that want to play a more supportive role in the fight.

One thing to note is that when you land the beacon, it'll add another 50% true Crit chance, putting your true crit chance at about 150% after you activate [Argon Scope].

You could put on [Heavy Caliber], but that's generally not suggested since it'll make the beacon fly absolutely everywhere and make using the [Buzlok] in Eidolon fights pointless.

[Hammer Shot] is a decent mod to add due to the extra crit damage, but only if you have a decent riven (even then, just get the extra crit damage on a riven).

A good Riven makes this thing a lot better. Some attributes to strive for would be the usual +Damage, +Multishot or +Crit chance/damage. You can also go for +Fire Rate, +Projectile Flight Speed or some other QoL to make using it a bit easier. Negatives to shoot for are stuff like -impact or -slash. -Ammo Max can work too, but the other stats need to be worth it.
