This was my first actual go and doing this (as in, never tried before). This took 3 attempts to get done.

1st was learning.
2nd I got impatient.
3rd... I became patient.

This has been done on every subclass... The whole raid solo'd, so this is nothing new. However, it was fun and an easy way to get 5-10 spoils (grab the hidden chest on the way to confluxes).

Only notes here is keeping up-time on Woven Mail / Banner of War. When you go to refresh it, make sure the minotaurs aren't around.

If they activate a plate and you pop their head, it will still remain inactive. Once you pop their head off, even if they run through, it'll still form the spire. Loop them around until the Vault eventually opens and claim your spoils!
