According to this super informative reddit post. Oracle’s spawn in a specific order, every single time before the Templar fight. I’ve always thought it was random, but this will be super useful for anyone trying to do either speed runs or hard modes.
L1- left stairs
L2- Left near conflux
L3- Back left hidden from sight in most spots
Mid - Center at base of first stairs
R1-Opposite of L2
R2- On the right near where the right conflux spawns
R3- Back right at the top of the ramp up from templar
