With 2 madrigals you'll get 63 acc, precision from a geo gives 69 accuracy, torpor reduces the monsters evasion by 69, and if you throw a cor into the mix you can get hunters roll for an additional 55 - 70 acc depending on if the hat procs. Using some combination of those buffs you should be able to reduce the amount of accuracy needed by the player to around 1000, which is a far more reasonable number to shout for.
