Wait for the best endgame reflection which is sainguine reflection for me (reflection effect only happens after 200 kills). Vestal spam heal, judgement and stun skill (I only uses judgement for self healing vestal or and stun skill if my team are full health but sometimes I stun one last enemy with low stun resist to stress heal and heal my team), Jester spam battle ballad for always 95% accuracy, speed buff and +40% crit, stress heal skill and 2 bleed skills (I don't use finale because it's kinda ruin the team comp at least its for me), MAA retribution, defends skill, buff and bolster (saves for the last encounter), Shieldbreaker pierce, impale, adder's kiss and serpent sway (only swap impale to puncture before fighting Miller because winter breath). I use healing trinkets like Junia's head and Sacred scroll for Vestal, Bright tambourine and Overture box for Jester, Mirror shield and Ancestor's coat for MAA, Spectral speartip and Legendary bracer.

Vestal/Jester/MAA/Shieldbreaker is just the ultimate team for farmstead that's great all around.
